Larry,
Please try these 3 different flavors of the Sheevaplug DTB.
1. The original DTB
2. kirkwood-sheevaplug_no_regulator.dtb
3. kirkwood-sheevaplug_active_low.dtb
Run each it with kernel 5.10.7 and kernel 6.10.11.
And do not run init_ionics mode bootup before boot.
And then post the complete serial boot log for each test (until the USB is disconnected or remains connected at lsusb command).

bodhi,
You have cracked the code! You are amazing.

I did not receive an email notification of this edit, so I didn't know about it. The response below does not include all those log files. After you read the results, let me know what I should re-run and capture for you.

The Nimbus U-Boot ubi_boot environment variable issues an init_ionics mode bootup command before anyting else:
5.10.7-kirkwood-tld-1
1. [UBIFS] /boot/uImage -> uImage-5.10.7-kirkwood-tld-1
6.10.11-kirkwood-UBIFS-2
(My modifications to your 6.10.11-kirkwood-tld-1 to add UBIFS support and compress modules)
1. [UBIFS] /boot/uImage -> uImage-6.10.11-kirkwood-UBIFS-2
This time we boot the UBIFS kernel using run ubi_boot, that is, we do run init_ionics mode bootup before boot.
The init_ionics mode bootup command causes no harm.
3. [UBIFS] /boot/uImage -> uImage-6.10.11-kirkwood-UBIFS-2-active_low
And, finally, we boot the USB drive using the 6.10.11-kirkwood-UBIFS-2-active_low kernel. (I could try your stock 6.10.11-kirkwood-tld-1 kernel with the kirkwood-sheevaplug_active_low.dtb, but I think there's little more to learn about the success you've made.)
3. [UBIFS] /boot/uImage -> uImage-6.10.11-kirkwood-UBIFS-2-active_low with [USB ext2] /boot/uInitrd
Let me know how you want to wrap this up. I am heppy to help you test your upcoming 6.11.x kernel, if you like.
Thank you so much,
Larry Baker

Let me know how you want to wrap this up. I am heppy to help you test your upcoming 6.11.x kernel, if you like.
Thank you so much,

Hi Larry,
Cool!
So looks like my original observation was correct! But've we got side tracked by the wrong assumption that this Nimbus 100 is a Sheevaplug clone. And now having seen the patch, it has confirmed my observation once more. The GPIO 29 bit should be set to Low.
Let me create a proper DTS source for the Nimbus 100 (currently it is patched on top of the Sheevaplug DTB), compile the DTB, and then you can try regression test it once more, and then we declare it's done!

Larry,
Please test the new kirkwood-nimbus-100.dtb with kernel 6.10.11+.
If it's all working OK, you can copy the other 2 files to your source tree at arch/arm/boot/dts/marvell/. The proper patch will be part of the next kernel release 6.11.x.
kirkwood-nimbus-100.dts
Makefile
=====
Please also rename this thread subject (1st post) to "Debian on Ionics Nimbus 100". That way it's easier for people to find.

bodhi,
> This is a better version.
Yes, it boots.
This time I left the USB drive plugged in when I booted from the UBIFS. I noticed that the USB disconnect still occurs early in the boot. But, later in the boot, the USB drive is re-enumerated and appears in lsusb when I login. So does a generic SCSI device, /dev/sg0:
When I boot the "nimbus-100" kernel with the Debian 11 USB rootfs there is no /dev/sg0 device:
Perhaps the creation of /dev/sg0 is a difference between the Debian 11 USB rootfs and the Debian 12 UBIFS rootfs. Or, maybe the creation of /dev/sg0 only occurs when devices are enumerated after the rootfs is mounted?
I'll have a look later at what happens booting the UBIFS roots with and without the USB rootfs with your 5.10.7 kernel and the "nimbus-100" DTB file.
I have to leave now.
Thanks again.

Perhaps the creation of /dev/sg0 is a difference between the Debian 11 USB rootfs and the Debian 12 UBIFS rootfs. Or, maybe the creation of /dev/sg0 only occurs when devices are enumerated after the rootfs is mounted?
I'll have a look later at what happens booting the UBIFS roots with and without the USB rootfs with your 5.10.7 kernel and the "nimbus-100" DTB file.
I have to leave now.
Thanks again.

Larry,
The difference is the first run, ubi_boot also executes "init_ionics mode bootup"
The 2nd run does not execute "init_ionics mode bootup"
The 1st run behavior.
When we run "init_ionics mode bootup", the USB power bit is set and the LED bit is clear. This is a coding error in that command init_ionics. During boot, there is not enough power so the USB storage got disconnected. Later, the DT regulator kicks in, and that's when full power is applied again to the USB port.
The 2nd run behavior.
Since the USB power GPIO is clear (active low logic), the power is kept constantly throughout.
You could run another test with run ubi_boot, but without the init_ionics command
======
I've noticed you have a problem with the kernel loading.
The uInitrd load address should be 0x2100000. Here is the referenced instruction in the Wiki thread
With the fix for initrd load address, you can use the bootarg root=LABEL=rootfs to tell the kernel to find the rootfs automatically. IOW, there is no need to use root=/dev/sda1, which error prone on a multiple USB drives configuration.

I have had the Nimbus SDK since I bought the Nimbus over 10 years ago. I put it on my Google Drive:
Nimbus 101 SDK v6.1-p1.tar.bz2
You can grab it from there. I have no idea whether it will help you with the Stratus and Cirrus boxes.

Yet, what puzzles me is when I run Debian 11 on USB, the 5.10.0-32-marvell kernel comes up just fine with init_ionics mode bootup. The USB drive is enumerated early and there is no disconnect. Should not that have had the power problem you describe since Linux doesn't know from the kirkwood-sheevaplug.dtb appended to that kernel that the USB Power pin is inverted? I don't think Linux 5.10.x actively managed USB power anyway, so it would not have altered the USB Power pin from the init_ionics mode bootup setting. I run Debian 11 off USB that way just fine. It is Debian 12 with its 6.1.0-25-marvell kernel and appended kirkwood-sheevaplug.dtb that disconnects the USB drive after enumerating the partitions.
> The 2nd run behavior.
> Since the USB power GPIO is clear (active low logic), the power is kept constantly throughout.
The just happened to be the way I booted the hybrid UBIFS uImage with the USB uInitrd and USB rootfs. The way it normally boots up the Debian 11 USB rootfs (the default bootcmd), init_ionics mode bootup is the first command given.
> I've noticed you have a problem with the kernel loading.
Good catch. I forgot about how much larger your kernels are than the Debian kernels. It didn't matter anyway, because I don't need anything in the uInitrd to successfully boot up the Debian 11 USB rootfs.
> you can use the bootarg root=LABEL=rootfs
I thought about that before, but I knew the drive was enumerated as sda1, so that's what I used.
I want to compare apples and apples. Over the weekend I will install Debian 12 on a USB stick running on my SheevaPlug. Then I'll peel away the kirkwood-sheevaplug.dtb off their kernel uImage and tack on your kirkwood-nimbus-100.dtb. That USB stick should then be bootable on my Nimbus. Then I can compare the two bootup message streams.
Assuming that looks great, I do want to know what your advice is about flashing a more recent SheevaPlug U-Boot on my Nimbus. We'll discuss that after I see what Debian 12 on USB looks like.
I owe you one.

Ray,
In case your Ionics Kirkwood devices are bricked, attached are my notes to backup and restore my Ionics Nimbus. Instead of overwriting the rootfs on the recovery USB, you can leave the original factory rootfs alone and restore the system the way it came from the factory. Of course, it will be the Nimbus rootfs. I have no idea how that may work on your boxes.
Regards,
Larry Baker

The kernel code changes from 5.10.x to 5.15.x have a lot to do with that behaviour.

Not true, it does. But perhaps bad assumption was made in 5.10.x and earlier, and then later somewhere before 5.15.x, the pinctrl and/or regulator drivers were fixed to correct that. So now it does the right thing, but causing problem for old code.

The init_ionics command in stock u-boot does nothing special, just flashing the LEDs during boot, and then provide a way to shutdown. Since you are booting Debian, this command is not needed.

Booting Debian without initrd causes many limitation and restriction that you don't want to have. Note that this is not applicable to distro such as Arch or OpenWrt, where the standard is booting without initrd (needed modules are built into the kernel image).

Yes indeed for this configuration with 1 USB drive.
However, this should be corrected because as soon as you plug in a USB hub and connect multiple drives, if one of them is the rootfs drive that you want to boot to, then you'll have booting problem because /dev/sda could be assigned to any of those drives (the order of enumeration is unpredictable).

bodhi,
Here's what I have learned this weekend.
I installed Debian 12 to USB on a SheevaPlug, Linux version 6.1.0-26-marvell.
It booted fine (kernel image plus initrd) on the SheevaPlug.
I renamed the Debian 12 uImage (with their kirkwood-sheevaplug.dtb) to uImage-sheevaplug.
I created a uImage-nimbus from their vmlinuz-6.1.0-26-marvell and your kirkwood-nimbus-100.dtb.
I created a uImage soft link that points to either uImage-sheevaplug or uImage-nimbus for U-Boot.
1. uImage-sheevaplug on SheevaPlug boots fine, as expected.
2. uImage-nimbus on SheevaPlug also boots fine, which surprises me. Why didn't the difference in the USB Power GPIO Active Low/High setting cause problems?
Other than the timestamp jitter and a few changes in the order of completion of the systemd steps, the only difference in the startup messages was:
3. uImage-sheevaplug on Nimbus as-is fails to mount the USB rootfs and gives up. The boot log shows no USB drives found. No surprise.
4. uImage-nimbus on Nimbus as-is also fails; the kernel does not even start. Why? There must be something in the initrd that doesn't match between a SheevaPlug and a Nimbus. It should not be the UUID of the rootfs, since that is the same USB drive. What then? (I hate initrd's. They are opaque and can do anything they want to in their init, without documentation or standards. Not like a straightforward Linux kernel boot.)
5. uImage-nimbus on Nimbus with rootfs bootargs works fine after I added "rootfstype=ext2 root=/dev/sda1 rw" to the bootargs. Why does Nimbus need these whereas SheevaPlug does not? There is some collusion between the kernel and the initrd, but what? And why is it different between the two? (One of the many reasons why I hate initrd's!)
I compared the boot logs of the 1. uImage-sheevaplug on SheevaPlug with this 5. uImage-nimbus on Nimbus with rootfs bootargs. As above, there is timestamp jitter and a few changes in the order of completion of the systemd steps, and the same difference in the OF: fdt: message:
Kernel command line (expected):
I saved all the boot logs from the five different runs above, if you want to see them.
I build my own minimal Debian 12 rootfs for the internal UBIFS flash rootfs. I do not use an initrd. It works fine, like on a PC Linux box.
Besides shrinking the footprint using compressing kernel module files, which we already discussed, I also removed all the DEBUG options except those enabled in the default ARM Multi_V5 configuration file in the 6.10.11-UBIFS-2 kernel I use:
Finally, I recall reading a post requesting "Help flashing to a Sheevaplug NAND", https://forum.doozan.com/read.php?2,135980. I think that is how I found your forum. Would you like me to post my instructions for creating a minimal Debian 12 (bookworm) rootfs for the internal UBIFS flash rootfs, and my instructions for creating the UBIFS volume? In which main topic area? It sounded like the author gave up on his attempts to install Debian 12 and went to OpenWrt instead. If his application is better suited to a more mainstream, flexible, and tailorable distribution, he may prefer Debian. That is my preference for my SheevaPlugs and Nimbus.
P.S. Ray was looking for a DTB in the Nimbus SDK. I hadn't thought of that before. I checked, and there is none. Ionics did include their kernel config file and their kernel patches, along with their patches to U-Boot and a small rootfs.
Thank you,
Larry Baker

It should not be the UUID of the rootfs, since that is the same USB drive. What then? (I hate initrd's. They are opaque and can do anything they want to in their init, without documentation or standards. Not like a straightforward Linux kernel boot.)
5. uImage-nimbus on Nimbus with rootfs bootargs works fine after I added "rootfstype=ext2 root=/dev/sda1 rw" to the bootargs. Why does Nimbus need these whereas SheevaPlug does not? There is some collusion between the kernel and the initrd, but what? And why is it different between the two? (One of the many reasons why I hate initrd's!)
I compared the boot logs of the 1. uImage-sheevaplug on SheevaPlug with this 5. uImage-nimbus on Nimbus with rootfs bootargs. As above, there is timestamp jitter and a few changes in the order of completion of the systemd steps, and the same difference in the OF: fdt: message:
[ 0.000000] OF: fdt: Machine model: Globalscale Technologies SheevaPlugversus

lsmod was the same on both systems.
I saved all the boot logs from the five different runs above, if you want to see them.
I build my own minimal Debian 12 rootfs for the internal UBIFS flash rootfs. I do not use an initrd. It works fine, like on a PC Linux box.
Besides shrinking the footprint using compressing kernel module files, which we already discussed, I also removed all the DEBUG options except those enabled in the default ARM Multi_V5 configuration file in the 6.10.11-UBIFS-2 kernel I use:
$ ARCH=arm CROSS_COMPILE=arm-none-eabi- make mrproper $ ARCH=arm CROSS_COMPILE=arm-none-eabi- make multi_v5_defconfig $ cp .config ../bodhi/config-6.10.11-multi_v5_defconfigI compared the DEBUG choices in that config file with my UBIFS-enabled version of your 6.10.11 config file and kept only theirs, except DEBUG_INFO:
$ ARCH=arm CROSS_COMPILE=arm-none-eabi- make mrproper $ grep DEBUG ../bodhi/config-6.10.11-multi_v5_defconfig | \ grep -v "^# " | grep -v "DEBUG_INFO" | sort >.config $ grep DEBUG_INFO ../bodhi/config-6.10.11-kirkwood-UBIFS | \ grep -v "^# " | sort >>.config $ grep -v DEBUG ../bodhi/config-6.10.11-kirkwood-UBIFS | \ sed -e 's/-kirkwood-UBIFS/-kirkwood-UBIFS-2/' >>.config $ ARCH=arm CROSS_COMPILE=arm-none-eabi- make olddefconfig $ cp .config ../bodhi/config-6.10.11-kirkwood-UBIFS-2That shrunk the kernel so the space penalty of adding UBIFS support went away. I encourage you to trim DEBUG options you no longer need in your upcoming 6.11.x release. I am looking forward to it. :)
Finally, I recall reading a post requesting "Help flashing to a Sheevaplug NAND", https://forum.doozan.com/read.php?2,135980. I think that is how I found your forum. Would you like me to post my instructions for creating a minimal Debian 12 (bookworm) rootfs for the internal UBIFS flash rootfs, and my instructions for creating the UBIFS volume? In which main topic area? It sounded like the author gave up on his attempts to install Debian 12 and went to OpenWrt instead. If his application is better suited to a more mainstream, flexible, and tailorable distribution, he may prefer Debian. That is my preference for my SheevaPlugs and Nimbus.
P.S. Ray was looking for a DTB in the Nimbus SDK. I hadn't thought of that before. I checked, and there is none. Ionics did include their kernel config file and their kernel patches, along with their patches to U-Boot and a small rootfs.
Thank you,

If any of your testing were done without uInitrd and failed to mount rootfs using partition label rootfs, then that test does not count. initrd is required when you use the partition LABEL option for root device.

The answer is no :) You've stripped out too many useful debug options by doing that. Debug configs should be selectively included. We are hacking Linux devices, a lot of times without documentation, certain debug options are very important for the process.
I don't have kernel size problem anymore with UBIFS configured in kernel 6.11.x and some other modules moved out to initrd. I also removed some insignicant DEBUG configs, but they did not make much difference, if at all.

I do recommend using OpenWrt if people run their system entirely on flash. I don't recall if I did in that case.

OpenWrt is a great mainstream distro for routers and true embedded devices. Debian is a server and/or desktop oriented distro. What we do here is providing a way to run old (i.e inexpensive) and low memory devices as Debian servers with latest Linux kernel.

To each his own! you are an experience Linux user so you can manage your own. But I always discourage people from all-flash solution if their boxes have low NAND capacity and trying to squeeze the rootfs into it. It's better to use OpenWrt if the goal is to use flash for rootfs.

No, it is not possible that there is any DTB in Nimbus SDK. Its stock kernel is old, from way back. Flatten Device Tree did not exist back then.
So Ray can use my newly created DTS and add to that for the other Nimbus models.

bodhi,
Fair enough.
> initrd is required when you use the partition LABEL option for root device.
When booting from UBIFS flash rootfs, there is only one choice for root=ubi0:rootfs (or whatever you have named the MTD partition), so LABEL= is not really helpful.
> But I always discourage people from all-flash solution if their boxes have low NAND capacity and trying to squeeze the rootfs into it.
The alternative is to build a custom rootfs using debbootsdtrap and debuerreotype, as I do. I have over half the ~500 MB rootfs space available (since I compressed the kernel modules). I could have an even larger MTD "rootfs" partition by eliminating the "kernel" (unused, in my case) and "pluginfo" MTD partitions, but I have not needed to do that. (Nimbus includes flash recovery tools in their "pluginfo" partition.)
> OpenWrt is a great mainstream distro for routers and true embedded devices.
It is also a good out-of-the-box solution for people that don't care to build their own custom kernels and/or rootfs.
Thank you for all your help. Again, should you benefit from testing your upcoming 6.11.x kernel, I volunteer to help out.

Larry,
Perhaps there is a bug somewhere in the regulator code.
I meant when you boot with USB rootfs.
Sure, it will be next month, after Linux stable tree has a couple more releases. Thanks!

2. uImage-nimbus on SheevaPlug also boots fine, which surprises me. Why didn't the difference in the USB Power GPIO Active Low/High setting cause problems?
Perhaps there is a bug somewhere in the regulator code.

I knew there would be no DTB as the source is too old. I was looking for the patches as that would potentially provide the information needed to create an appropriate device tree.

Bodhi,
> Perhaps there is a bug somewhere in the regulator code.
Or that regulator code had not been fully implemented in the 6.0.x kernel. That status message about setting the USB Power active low does not appear until the 6.2 kernel.
I plan to use your 6.10.11 kernel until you come out with your 6.11.x kernel. I can see what happens pairing the 6.10.11 kernel with the wrong DTB. I have to clean up all the debris from the tests I have been making and straighten out the configuraton and documentation of the UBIFS rootfs I want to use for my application first.
> I meant when you boot with USB rootfs.
Of course. That is when it makes sense. The use case for a flash rootfs is to be as small as possible, i.e., avoid the extra space for a uInitrd.
What is your opinion about updating the Nimbus U-Boot? Is it worth it? E.g., for ext3/4 and other file system support?
As far as I can tell, there are only two significant differences between the SheevaPlug U-Boot code (unpatched 2011.03-rc1) and the Nimbus U-Boot code (2011.03-rc1 with Nimbus patches).
The first is the initialization of the USB Power in board/Marvell/sheevaplug/sheevaplug.c. It looks like all the GPIO pins are active low on the Nimbus. They also initialize both Output Enable registers to drive all the GPIO outputs. The SheevaPlug U-Boot tri-states all the GPIO outputs.
In board/Marvell/sheevaplug/sheevaplug.h:
Nimbus sets bits 9:11, Write recovery for auto-precharge, in the DDR Mode register to 3 instead of 6:
Nimbus is missing the CS[0]n Base address register. Since the default value is 0x0, this is harmless. Nevertheless, it is sloppy.
Nimbus incudes values for the L2 RAM Timing registers. They should probably not be there, since Linux complains when it sets up L2 cache:
That leaves the USB Power setting as the only significant difference. It looks like Linux 6.10.11 manages USB power correctly. The DTS file also says the USB power regulator should always be on and should be on at boot. That takes care of Linux.
What about U-Boot? What will happen in a more modern SheevaPlug U-Boot if at power up U-Boot does not enable USB Power on Nimbus? Would I still be able to read or boot a USB drive? I can't tell. I tried flipping the USB Power GPIO bit in the GPIO Data Out register in U-Boot, but I didn't notice it made any difference. I could still start USB and see the USB drive with usb info.
Would a more modern U-Boot with your kirkwood-nimbus.dtb appended set up USB Power active low? I have never dealt with DTBs when I have rebuilt U-Boot before. I don't know the process, and I don't know where the U-Boot DTBs come from. Are they full-flown Linux DTBs, or are they stripped down versions?
Or, would you recommend I leave well enough alone? That is a perfectly reasonable choice for me. I might lose the ability to boot an ext4 USB drive, but that is not of interest to me anyway.
Thank you,
Larry Baker

Nimbus sets bit 16 in the DDR Configuration register:
0 = To Store: Write buffer configure to store & forward mode 1 = To Cut: Write buffer configure to cut through modeWhile cut through mode may have a subtle affect on performance, I don't think changing the setting to store & forward mode will cause any incorrect behavior.
Nimbus sets bits 9:11, Write recovery for auto-precharge, in the DDR Mode register to 3 instead of 6:
Write recovery for auto-precharge NOTE: This device does not support auto-precharge. Must be 0x3.According to the manual, 3 is actually the correct value.
Nimbus is missing the CS[0]n Base address register. Since the default value is 0x0, this is harmless. Nevertheless, it is sloppy.
Nimbus incudes values for the L2 RAM Timing registers. They should probably not be there, since Linux complains when it sets up L2 cache:
[Firmware Bug]: Feroceon L2: bootloader left the L2 cache on!It looks to me like the custom Nimbus memory configuration settings are not necessary.
That leaves the USB Power setting as the only significant difference. It looks like Linux 6.10.11 manages USB power correctly. The DTS file also says the USB power regulator should always be on and should be on at boot. That takes care of Linux.
What about U-Boot? What will happen in a more modern SheevaPlug U-Boot if at power up U-Boot does not enable USB Power on Nimbus? Would I still be able to read or boot a USB drive? I can't tell. I tried flipping the USB Power GPIO bit in the GPIO Data Out register in U-Boot, but I didn't notice it made any difference. I could still start USB and see the USB drive with usb info.
Would a more modern U-Boot with your kirkwood-nimbus.dtb appended set up USB Power active low? I have never dealt with DTBs when I have rebuilt U-Boot before. I don't know the process, and I don't know where the U-Boot DTBs come from. Are they full-flown Linux DTBs, or are they stripped down versions?
Or, would you recommend I leave well enough alone? That is a perfectly reasonable choice for me. I might lose the ability to boot an ext4 USB drive, but that is not of interest to me anyway.

bodhi has taken care of that for us. It seems to be working well for the newer Linux kernels that are more actively managing USB power. The Nimbus GPIO data output are all active low, so he changed the USB Power and the two LED definitions from active high to active low.
See his https://forum.doozan.com/read.php?2,138142,138266#msg-138266 post. He attached both a kirkwood-nimbus.dtb and dts.

That was just more information spitting out by the regulator driver. Regulator is quite old so I would not say it's lacking something. The behavior seems to be a bug. The info message might be added when they fixed a real bug.
I have not looked at the regulator code and comparing versions. But I can smell a bug there :) I could explain my theory if anyone is curious.
However, it's really academic by now that we knew how that part of the Nimbus 100 was implemented, and adjust the DTS accordingly.

There are things that old u-boot cannot do, such as reading Ext4. But that's not really important to your purpose. Ext4 is supported in Linux after booted.

bodhi,
I have created a Debian 12 Nimbus installer uImage using your Nimbus 100 DTB and hacked the Debian installer to support the Nimbus 100. Here are my notes.
(I have attached a PDF of my own installation documentation that is specific to my application and includes my customizations to create a basic Linux system ready for the installation of my application, esp. to install ntp for timekeeping.)
Install Debian 12 Kirkwood ARMEL Linux on a Nimbus 100
The Ionics Nimbus 100 is a repackaged version of the Marvell SheevaPlug. Until Debian 12, Debian SheevaPlug installers could install Linux on a Nimbus 100. Unfortunately, as of Debian 12, that is no longer the case. To install Debian 12 on a Nimbus 100, we must modify the Debian 12 SheevaPlug installer to support the Nimbus 100.
The Debian 12 “bookworm” SheevaPlug installer does not enumerate the USB installation drive on a Nimbus 100, whereas the Debian 11 “bullseye” SheevaPlug installer does. This is because of changes in Linux in the management of USB power between Debian 11 and Debian 12.
While the Nimbus 100 is a SheevaPlug clone, it is not precisely the same. One difference is the GPIO outputs are inverted. Thus, on a SheevaPlug, the GPIO USB Power pin is “active high”. On a Nimbus, it is “active low”. As a result of changes to the USB power management in the Linux kernel beginning with version 5.15, USB devices no longer function on a Nimbus that is running a Linux kernel bound to the SheevaPlug DTB. (And there are no alternatives.) Debian 11 uses a Linux 5.10 kernel; Debian 12 uses a Linux 6.1 kernel.
SheevaPlug and Nimbus boot from a Linux kernel uImage, which is a bundle of a compressed Linux kernel binary with a Device Tree Blob (DTB) that describes the hardware. Debian SheevaPlug installers bundle the SheevaPlug DTB. The SheevaPlug DTB defines its GPIO USB Power pin as “active high”. This is the reverse of the GPIO USB Power pin polarity on a Nimbus. As a result, a Nimbus fails to energize the USB port, thus preventing the recognition of any USB devices. (See Debian on Ionics Nimbus 100 for a discussion of the topic.)
To install Debian 12 on a Nimbus, we need a Debian 12 installer that bundles the Nimbus 100 DTB. Luckily, a Nimbus DTB file has been written by “bodhi”, a Linux embedded systems expert at the Linux Device Hacking forum.
Create a Debian 12 “bookworm” Nimbus 100 Installer
Login to a suitable account on a Linux PC. (I use the root account because I create files in /opt.)
I use minicom to connect to the Nimbus 100 USB console port. Configure the serial port (Serial port setup), /dev/ttyUSB0, for 115200 baud, 8 data bits, no parity, 1 stop bit, and no flow control.
You will need to install minicom, wget, and uboot-tools (for mkimage).
Download the Nimbus 100 DTB file from https://forum.doozan.com:
Plug the USB drive with the Debian 12 Nimbus 100 installer into the Nimbus.
Connect the USB console cable to the Nimbus and power it on.
Run minicom.
Power up the Nimbus and interrupt the boot loader (Hit any key to stop autoboot:):
Start The Installation
Continue the minicom Nimbus console session from above.
Plug a USB drive for the installation into the Nimbus.
Plug the Nimbus Ethernet port into an Internet router with DHCP support.
Start the installer:
Because the Debian 12 SheevaPlug installer’s archdetect program does not recognize the Nimbus 100, it returns armel/generic for the architecture. The architecture should be kirkwood, the family name of the SoC CPU chip used in a SheevaPlug and a Nimbus 100. Because of that, the installer fails to find a suitable kernel.
As a workaround, create a replacement for the installer’s archdetect program that always returns kirkwood.
Type <CTRL-A> <CTRL-A> 2 from minicom to switch to console 2 when the Debian installer screen appears.
Replace the Debian 12 archdetect program with a shell script that always returns kirkwood:
Proceed with the Installation
To monitor the progress of the installation, switch to console 4 from minicom by typing <CTRL-A> <CTRL-A> 4. The installation session is on console 1. Consoles 2 and 3 are BusyBox shell sessions.
Select the Debian options you want for your system.
If the installer fails to find a suitable kernel, proceed with the installation, but do not exit the installer when the installation is complete. This should not happen with the workaround described above in place.
When the Installation complete window appears, do not Continue to reboot.
If necessary, continue to the next section to install the Linux kernel. Otherwise, proceed to the following section to prepare the Linux kernel U-Boot boot loader files.
Manually Install the Linux Kernel if the Installer Fails to Find a Suitable Kernel
Follow these instructions if the installer fails to find a suitable kernel.
This should not happen with the workaround described above in place.
Enter <CTRL-A> <CTRL-A> 2 from minicom to switch to console 2.
chroot to the target root volume and install the linux-image-marvell kernel:
Manually Prepare the Linux Kernel U-Boot Boot Loader Files
Preparation of the Linux kernel uImage and uInitrd U-Boot boot loader files is performed by the Debian 12 installer flash-kernel script. As was the case for the archdetect program, the stock flash-kernel script does not recognize the Nimbus 100 and exits. The dpkg log in console 4 displays the message “Unsupported platform 'Ionics Nimbus 100'.”
Unlike the archdetect program, that had to be replaced above, the flash-kernel script has provisions to add support for additional platforms. The changes made here will enable flash-kernel to support Nimbus 100 for the installation as well as for future Linux kernel updates.
Enter <CTRL-A> <CTRL-A> 2 from minicom to switch to console 2.
Download the Nimbus 100 DTB file from https://forum.doozan.com: to the target /etc/flash-kernel/dtbs/ directory:
With these entries, flash-kernel will only create uImage and uInitrd; flash-kernel will not attempt to copy uImage to an MTD flash partition.
Finish the Installation
Select Continue to finish the installation and reboot the Nimbus.
Interrupt the boot loader when the Nimbus restarts (Hit any key to stop autoboot:):
Resume the minicom session on the Nimbus console.
Configure U-Boot to boot the Debian 12 rootfs on the USB drive (an ext2 file system labeled COMLOGGER in my case):
QED
That's it! You can login and customize your installation. Every time you power up or reset your Nimbus, it will boot the Debian 12 USB rootfs.
Postscript:
Define the MTD Flash Partitions in the U-Boot Linux Boot Command
There is no partition map for the MTD flash partitions; they must be properly defined for the Linux kernel from the U-Boot configuration.
The U-Boot mtdparts variable must be defined with the MTD partitions map:
Add the cmdlinepart.mtdparts kernel boot option to the U-Boot Linux boot command:

That's it! You can login and customize your installation. Every time you power up or reset your Nimbus, it will boot the Debian 12 USB rootfs.
Postscript:
Define the MTD Flash Partitions in the U-Boot Linux Boot Command
There is no partition map for the MTD flash partitions; they must be properly defined for the Linux kernel from the U-Boot configuration.
The U-Boot mtdparts variable must be defined with the MTD partitions map:

Should be driver-policy=dep to make the initrd smaller right of the bat. But this step can be done later after the system is running.

bodhi,
> fatload usb 0:1 0x02100000 bookworm-sheevaplug-installer-uinitrd
The Debian kernel is only 2.5 MB. It's their initramfs that is HUGE! (A consequence of their driver policy, as you know.) The load address I used is from Martin Michlmayer's instructions. It is fine for Debian's kernel, but not for yours.
I did have a hiccup in the Debian 12 installation on Nimbus. It could not find a suitable kernel. I traced the problem to the FLAVOUR variable being empty. FLAVOUR=arch_get_kernel_flavour() (in armel.sh), which returns "marvell" if SUBARCH is either kirkwood or orion5x, else "". SUBARCH=archdetect, whose source code I cannot find. archdetect returns something like armel/generic (I forgot to write it down). I did not have this problem with the Debian 12 installer on my SheevaPlug. I am going to fire up the installer again on my SheevaPlug and see what archdetect returns there. Meanwhile, I'm installing apt-file so I can search for where archdetect comes from. (I told you before, I don't run Debian except on these SoCs. Every time I reinstall, I have to add packages again. :) )
Cheers,
Larry Baker

bodhi,
I ran archdetect on console #2 immediately after the Debian 12 installer screen appeared on both my SheevaPlug and my Nimbus.
On SheevaPlug:
Is there something in the Nimbus DTB that could explain this?
I am going to follow the instructions at DebianInstaller Checkout to try to find the source code for archdetect. Once I know how it comes up with its response, I can pass that along to you in case a new version of the Nimbus DTB will fix this problem.
Thank you,
Larry Baker

Arch Kirkwood is correct. It's should be defined in the kernel config. The DTB does not define the board architecture.

bodhi,
I assumed the Debian 12 kernel I downloaded from http://ftp.debian.org/debian/dists/bookworm/main/installer-armel/current/images/kirkwood/netboot/vmlinuz-6.1.0-25-marvell is the same kernel in the Debian 12 installer at http://ftp.debian.org/debian/dists/bookworm/main/installer-armel/current/images/kirkwood/netboot/marvell/sheevaplug/uImage. Perhaps that was a mistake.
I'll boot the Debian 12 installer uImage on both my SheevaPlug and my Nimbus and see what archdetect says. If they both say armel/kirkwood, then I'll have to unwrap the Debian 12 installer uImage to use that kernel with your Nimbus DTB.
Thanks for the info.

Well, something fishy is going on and the evidence points to the Nimbus DTB file. Why? I don't know yet.
I created two Debian 12 installer uImage's using their Kirkwood vmlinuz file, one with their SheevaPlug DTB and one with the Nimbus DTB file. I ran those two on my Nimbus, as well as the stock Debian 12 installer uImage. The same 6.1.0-25-marvell kernel is in all three (proof below). archdetect returns armel/kirkwood for both uImage's with the SheevaPlug DTB. It returns armel/generic for the uImage with the Nimbus DTB.
Here's exactly what I did (from the history command). I am doing the uImage manipulation on a Linux x86_64 PC and writing the results to a USB FAT drive. I then run each Debian 12 installer on my Nimbus.
Create Debian 12 installer uImage files using the Debian 12 vmlinuz-6.1.0-25-marvell
kernel with the Debian 12 kirkwood-sheevaplug.dtb and the bodhi kirkwood-nimbus-100.dtb
While you ponder this, I am going to download the Debian Installer sources to figure out how archdetect works.
More later.
