Debian on iomega storcenter ix4-200d: succes!

Posted by damacc 
Hi bodhi,

How can I do this when I have a wholeflash backup file. I suppose I would have to boot the board with kwboot and this wholeflash image, and then flash it into nand flash. Is this correct?

Yes.

- Format a USB flash drive as ext2 or ext3. Put the mtd NAND dump files on the root folder.
- Boot with kwboot using the stock mtd0.
- Load mtd0 file to memory.
- And do nand flash erase and nand write.

After this you can boot normally with u-boot. And the next step depending on whether you want to boot Debian first or restore stock first.

1 .To boot Debian first,
- create Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2 rootfs on USB: http://forum.doozan.com/read.php?2,12096.
- follow damacc posts to adjust u-boot envs in serial console to boot into Debian.
- and then flash the rest of the stock mtds in Debian.

2. To boot stock first,
- Do flash erase and nand write for each mtds in serial console.

I would recommend doing number 1 (booting Debian first).

And see here for flashing instruction for Pogo V4 mtd0 (section B):

Hi, I have a ix4-200d here collecting dust, I want to give a new chance... currently it has 4 hd 500gb each with stock firmware.

I want to throw away those disk and install and boot debian on a usb-stick, probably put other disk and maybe a zfs or ntfs there...

I have successfully written kernel, initramfs, and rootf on some HD for some Iomega Ez Media & Backup Center that I have around using some help from here too, my instructions are here: https://gist.github.com/braian87b/b5a4c5f20d1112473c470b096df766a3 those Iomega Ez have NTFS and ext4 and works extremely well so far.

Now I want to play with the ix4-200d, since I have very basic understanding, can someone point me to some url's with info and needed files on how to do it and explain briefly the steps to be able to do it?

I have some computers and vm's with debian and usb's sticks and usb-ttl also to start with this.

Thanks.

Hi, Bodhi provides instructions and a root filesystem to boot from usb here;
Kernel and rootfs

Scroll down to the rootfs instructions at: Updated 24 Jul 2017:

Basic Debian stretch Kirkwood rootfs for most Kirwood plugs


You will need to follow the 'append dtb to uImage' instructions, then change the u-boot parameters via a serial console to boot from usb.

First of all, thanks for all of the research done for giving new life to the ix4 box. I've one of these laying around myself and knowing it's possible to run debian on it would be a nice opportunity to set it up as a backup server with better disk management. But now having read all of the related posts here and tried out many described ways, I still couldn't manage to boot into debian.

I might have not understood everything what's going on and how it works, but here's what I've done so far:

- Setting up an USB stick with Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2 rootfs (as described in https://forum.doozan.com/read.php?2,12096)
-> Plugged into ix4 and turned on, but boots into normal firmware
- Tried aswell Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2 with same result (but shouldn't work anyways with stock uboot iirc)
- Attached serial interface, interrupted boot and set some env variables (as in https://forum.doozan.com/read.php?3,25120,25675#msg-25675) and tried "boot", but seems like it can't correctly init the usb stick and reboots:
Marvell>> boot

SysClock = 400Mhz , TClock = 200Mhz

- I've set the vars again and performed saveenv (probably not the smartest thing to do; now it tries to boot from usb by default, and fails)
- Tried to do a kwboot with different images such as uboot.2015.10-tld-1.sheevaplug.bodhi.tar, ix4-200d-mtd0.kwb and a mtd0 that was attached to some forum posts. Tried with command
kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2015.10-tld-1.sheevaplug.mtd0.kwb -p
but it stucks at
Sending boot message. Please reboot the target...\
no matter how often I reboot or interrupt with ctrl-c and re-do kwboot as described in an other topic
(https://forum.doozan.com/read.php?3,7852,7852)

I've often just seen the reference to the rootfs-post, but never actually an explaination on what to do after having the usb stick ready. Booting with serial and interrupt? The only thing I've found from that point were some posts where a custom uboot seemed already to be applied - which I couldn't load with kwboot.

I might also be totally wrong and doing pointless stuff, since I don't understand everything. But even after reading all of the posts multiple times, I couldn't figure out the clear steps to be able to boot into debian. Am I doing something wrong? Any help would be appreciated; I can also provide outputs or any other info if needed.

- Plug in the USB rootfs with Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2 on it.
- Power up, interrupt serial console and

setenv usb_set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 earlyprintk=serial'
setenv load_uimage 'ext2load usb 0:1 0x800000 /boot/uImage'
setenv load_uinitrd 'ext2load usb 0:1 0x2100000 /boot/uInitrd'
setenv usb_boot 'mw 0x800000 0 1; run load_uimage; if run load_uinitrd; then bootm 0x800000 0x2100000; else bootm 0x800000; fi'
setenv usb_bootcmd 'run usb_set_bootargs; run usb_boot'
setenv bootcmd 'usb start; run usb_bootcmd; usb stop; reset'
And then,
printenv
boot

The above instruction is in the Wiki thread:

You've raised a good point, I need to update the rootfs instruction to point to that post to recommend a basic approach when users are booting from stock Kirkwood u-boot.

Thanks for the fast response! Only thing not working so far is when setting the usb_boot env; it's not possible to save it:
Marvell>> setenv usb_boot 'mw 0x800000 0 1; run load_uimage; if run load_uinitrd; then bootm 0x800000 0x2100000; else bootm 0x800000; fi'
** Too many args (max. 16) **
Any workaround?

Edit: Oh nvm I should have rtfm. Will try again as described in the linked post :)

So setenv worked now, but I'm still experiencing the "Unknown command 'usb' - try 'help'" message after trying to boot. Might there be missing something, could it be usb not being created correctly or do you by occasion see anything wrong in the log? Does the partition table type matter on the usb stick (msdos for me)?

Here's the serial output from the beginning of startup to when it bootloops (when it's not being interrupted):

Radm,

I forgot that this box stock u-boot might not have usb command support.

Read this thread from the 1st post down, see if you can confirm that you have to boot from this ix4-200d box using the HDD "raw sectors".

After playing a bit around and reading even more posts, some good news: I've managed to flash stock uboot 1.1.4 which supports the usb command and to boot into debian. In case anyone needs the steps, this is how I've done it:

This implies you have some drives in the nas and a working installation of the default linux "distro" from iomega (the default one with the web-interface).

1. Startup the nas normally
2. Download the uboot-1.1.4-Mar-10-2011.mtd0 attachment from https://forum.doozan.com/read.php?2,22623,29586#msg-29586
3. Copy the image to the NAS and ssh into it
4. Write image to nand:
flash_eraseall /dev/mtd0
nandwrite -p /dev/mtd0 uboot-1.1.4-Mar-10-2011.mtd0
5. Reboot (or shutdown)

6. Prepare rootfs usb stick with Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2 (see https://forum.doozan.com/read.php?2,12096)
7. Attach serial, start the nas and interrupt at boot
8. Set env vars:
	setenv usb_set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 earlyprintk=serial'
	setenv load_uimage 'ext2load usb 0:1 0x800000 /boot/uImage'
	setenv load_uinitrd 'ext2load usb 0:1 0x2100000 /boot/uInitrd'
	setenv usb_boot 'mw 0x800000 0 1; run load_uimage; if run load_uinitrd; then bootm 0x800000 0x2100000; else bootm 0x800000; fi'
	setenv load_uinitrd 'ext2load usb 0:1 0x2100000 /boot/uInitrd'
	setenv usb_boot 'mw 0x800000 0 1; run load_uimage; run load_uinitrd; bootm 0x800000 0x2100000'
	setenv usb_bootcmd 'run usb_set_bootargs; run usb_boot'
	setenv bootcmd 'usb start; run usb_bootcmd; usb stop; reset'
	setenv rootfstype ext3
9. And then boot
boot


And there we go, booting into debian

Thanks bodhi for helping out :)



Ps. Is there meanwhile support for the small front display, or for controlling the fan? And is there a newer uboot I can flash on it, so I don't have to regenerate the uInitrd everytime an update-initramfs happens?

Radm,

Well done!

Let me take a look in the DTS. LCD support should have been in the kernel config. But the LCD must be also in the DTS to make it work.

You don't need new u-boot to do this. Debian flash-kernel will do this. But I've recommended removing it in the kernel upgrade instruction, since it is not a sure thing flash-kernel wil handle the customed kernel like ours correctly (there is a way to ensure flash-kernel will behave the way we want, but needs more set up).

Besides, each time you upgrade the kernel, or upgrade Debian, you should manually examine the result anyway. So regenerating uImage and/or uInitrd manually is not much more works.

With that said, if you want to set up some automatic Debian upgrade (or some trigger) it is possible to make sure the uInitrd will be recreated.

I don't think there is a driver/binding for this type of display (please correct me if I'm wrong about that).

Last year I wrote a python script which displays a bitmap on the screen (it can also be used to read the screen). Checkout lcd_test.py here:
https://github.com/1000001101000/ix4-200d-research

I was originally planning to do a bunch of other things for this device but ran into some roadblocks getting sata working on mine for some reason.

....I also took on too many projects shortly before my free time started getting shorter which led to a bit of a burnout, I don't know how bodhi does it!

Thanks, I defer to your experience about this :) I recall some binding for LCD in some Armada boxes. But I don't really know if this LCD needs some driver that is not in mainline yet.

I do get burnt out from time to time. Been on this forum for 10 years already :) But my cure of burn out is that I hope people get curious about my blog (in my signature) and visit it. And I just stop doing any more new hacking for a while, just helping out with problems here, and go read some books.

May be I can help looking at the log?

I believe the binding is for the shift-register that is used to multiplex the LEDs (I had fun writing a script to find those pins). As far as I could tell when I was looking into it there was no mainline driver for that kind of LCD though the person I originally forked that repo wrote one for the armada device which appeared to be based on the GPL code for that device. I wrote something vaguely equivalent in python which has the added bonus of using soem python libraries to handle converting the input image into something usable for the display code.

re-writing stuff that NAS vendors put in their custom kernel code as user space bash/python utilities is turning into a specialty of mine.
