Switch from Archlinux to debian
October 15, 2020 09:03PM
Hello. I'm new to this forum, and fairly new with the Pogoplug, but experienced with Unix/Linux.

I bought a Pogoplug V4-A3-01 that was configured by the previous owner to boot Arch Linux from USB drive. I'm booting debian from SD on my other Pogoplugs, which is what I'd like to do on this one.

I'm not able to see it on my network when I boot to the original Cloud Engines OS, so I booted to Arch Linux, and ran uboot.sh (pulled from http://ssl.pepas.com/pogo/uboot.sh). It says MD5 sums of /bin/busybox and /proc/version don't match, which of course they wouldn't since I'm not running the original OS.

But, I'm thinking it should be safe to do the override of that MD5 check ("export BRICK_MY_POGO=1") and let it do the U-boot update since it IS the correct hardware, but not sure if there are going to be any gotchas since I'm running it under Arch Linux rather than the orig. OS. I did comment out the /sbin/poweroff at the bottom of uboot.sh so I can try to recover while it's still up in case there are any errors running the script.

Do you agree that this should work? This is what I see for current U-Boot version.

[root@alarm ~]# grep -a --null-data U-Boot /dev/mtd0ro

Is this telling me there are two on /dev/mtd0? Will uboot.sh replace them both with just U-Boot 2014.07-tld-1?

Any/all help and suggestions appreciated!

rsantag,

There is only one u-boot on mtd0. The Pogo V4 mtd0 is 2MB (unlike other Kirkwood boxes which has 1 MB mtd0).

I'm not trying to discourage you from using pepas script. However, if you are an experienced Linux user then it is easy to follow the instruction in my u-boot release thread and install it from inside Arch Linux. The commands are pure Linux (not Arch specific).

Thanks for the quick reply. I've give it a go later today and post my results.

OK, downloaded the U-Boot and tools from dropbox. Extracted tools and moved to /usr/local/bin, and moved fw_env.config to /etc.
When I run fw_printenv I get Bad CRC error and only a handful of env variables are listed

[root@alarm etc]# fw_printenv
Warning: Bad CRC, using default environment
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootm
bootdelay=5
baudrate=115200
[root@alarm etc]#

But I did copy /usr/local/cloudengines/bin/* from another pogo-v4-a3-01 to this box, and it does show all the other env vars, incl. ethaddr

[root@alarm etc]# /usr/local/cloudengines/bin/blparam | grep ethaddr
ethaddr=00:25:31:05:18:a3
[root@alarm etc]# /usr/local/cloudengines/bin/blparam | wc -l
50
[root@alarm etc]#

Should I just use /usr/local/cloudengines/bin/blparam to set env vars when I get to that point? Or is there something I need to do to fix fw_printenv and fw_setenv?

No. Initially you have to use blparam to see the u-boot envs. But once you flash u-boot and u-boot envs image (Step 7 and Step 8), the envs are newly created on flash, and its location was adjusted in /etc/fw_env.config.

So at Step 8.e and later steps, you can use fw_setenv and fw_printenv.

OK, thanks again. That helped.

Hopefully the last question: Step e.2 says to restore mtdparts, but this wasn't set in the original env variables.

[root@alarm alarm]# grep mtdparts current_envs.txt
[root@alarm alarm]# wc -l current_envs.txt
50 current_envs.txt
[root@alarm alarm]#

However, I have another Pogo same model that it IS set:

root@pogoplug:~# fw_printenv mtdparts
mtdparts=mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)

Should I set to that?
Note that mtd0 on the new box has 1 more partition (no idea what the mtd5 partition is for)

root@pogoplug:~# cat /proc/mtd
dev: size erasesize name
mtd0: 00200000 00020000 "u-boot"
mtd1: 00300000 00020000 "uImage"
mtd2: 00300000 00020000 "uImage2"
mtd3: 00800000 00020000 "failsafe"
mtd4: 07000000 00020000 "root"
root@pogoplug:~#


[root@alarm alarm]# cat /proc/mtd
dev: size erasesize name
mtd0: 00200000 00020000 "u-boot"
mtd1: 00300000 00020000 "uImage"
mtd2: 00300000 00020000 "uImage2"
mtd3: 00800000 00020000 "failsafe"
mtd4: 07000000 00020000 "root"
mtd5: 00010000 00008000 "spi0.0"
[root@alarm alarm]#


And one final question: does it still boot the original OS (from Cloud Engines) if it doesn't find kernel files on any of the drives?

Yes, that's the correct mtdparts for Pogo V4.

You can ignore this.

It will not boot the CE stock OS. It is possible but extra steps needed (a little bit more involved with flash mtd).

Not a lot of people want to boot stock so I didn't provide instruction.

However, to make it possible, then right after you have backed up mtd0 in Step 3.


Quote

3. Be sure to save your current uBoot image in mtd0, or have a backup image saved somewhere as precaution. And save your current u-boot envs with fw_printenv, or just copy/paste the listing into a text file. Note the nanddump command below allows future restoration to the same box you're backing up, and also can be used to restore a differrent box's mtd0 if needed.

Dumping NAND mtd0:
nanddump --noecc --omitoob -l 0x80000 -f mtd0 /dev/mtd0

Do this in stock OS right after the nanddump above

cp -a mtd0 /uboot.mtd0.pogo_v4.original.kwb

And later I will show you how to boot back to stock if that's what you want to do so you can run stock FW as a rescue system.

Re: Switch from Archlinux to debian
October 16, 2020 11:37PM
Thanks. Yeah, that was my thought - as a rescue OS. My other Pogos are running the 2014 Uboot, which does boot to the stock OS if no SD or USB boot device.

I know the older U-Boot that I'm running on my other Pogos tries to boot off MMC, then USB, then Sata, then internal flash.

root@pogoplug:~# fw_printenv bootcmd
bootcmd=run bootcmd_mmc; run bootcmd_usb; run bootcmd_sata; run bootcmd_pogo; reset


But the newer boot loader seems to do things quite a bit differently, so I'm assuming I would need to somehow incorporate the equivalent of the bootcmd_pogo in the boot sequence

root@pogoplug:~# fw_printenv bootcmd_pogo
bootcmd_pogo=if ubi part root 2048 && ubifsmount ubi:rootfs && ubifsload 0x800000 uboot.mtd0.dockstar.original.kwb ; then go 0x800200; fi


But is uboot.mtd0.dockstar.original.kwb even still there, or was it on /dev/mtd0 and gets overlaid by the new U-boot? It's not super critical that I can boot the orig OS, but figured it would be a nice option if it can be done fairly easily. And I do like to understand how all the piece fit together. Haven't really ever done anything with a ubifs on a flash device, so this old dog trying to learn some new tricks.

Re: Switch from Archlinux to debian

OK, so digging into this a little more, my other Pogos have /uboot.mtd0.dockstar.original.kwb on the mtd4 root partition, which seems to be what bootcmd_pogo loads with ubifsload. I'm guessing this is the original, unmodified /dev/mtd0 uboot partition? So, the uboot.2014.07 uboot loads and runs this as a last resort, which in turn boots the original OS.

So, problem is that I'm not positive the /dev/mtd0 I dumped above with nanddump is an unmodified original uboot. The previous owner of the device had updated it to run Arch linux, so I'm guessing it's not. However, I do have /uboot.mtd0.dockstar.original.kwb. The other problem is, even if /dev/mtd0 on this device WAS the original, I was booted into Arch Linux, not original CE OS, so my copy just got saved to root on the Arch Linux USB drive. I wasn't able to boot to the original OS when I received it.

Is there a way to mount /dev/mtd4 to be able to write /uboot.mtd0.dockstar.original.kwb there? Or if not, maybe just use dd to save /dev/mtd4 from another Pogo-v4-A3-01, and write it to /dev/mtd4 on this device? Then, just need to tweak fw env variables, i.e. add the bootcmd_pogo as above and
change bootcmd_exec to

Quote

"if run load_uimage; then if run load_initrd; then if run load_dtb; then bootm $load_uimage_addr $load_initrd_addr $load_dtb_addr; else bootm $load_uimage_addr $load_initrd_addr; fi; else if run load_dtb; then bootm $load_uimage_addr - $load_dtb_addr; else bootm $load_uimage_addr; fi; fi; else run boot_pogo; fi"?

Would that work?

Note to readers: This is what we call "chainload u-boot" method. This method works only with very old u-boots, such as ones on these Kirkwodd boxes. If stock u-boot is newer than 2012 (2013 and newer), then most likely it cannot be chainloaded. Mainline u-boot circa 2011/2012 also could not be chainloaded.


Ralph,

You have a pretty good grasp on what the envs do in setting up booting stock u-boot.

So, problem is that I'm not positive the /dev/mtd0 I dumped above with nanddump is an unmodified original uboot. The previous owner of the device had updated it to run Arch linux, so I'm guessing it's not. However, I do have /uboot.mtd0.dockstar.original.kwb.

I wasn't able to boot to the original OS when I received it.

The original Arch Linux version of this u-boot is basically the same as stock. With some additional envs changes to boot Arch. So it can be used for chainload puposes. But it is no longer a clean boot (need to retrofit the stock envs on the fly).

You're correct that mounting stock rootfs to copy the orginal mtd0 on it would be best. Otherwise you would have to flash mtd0 back to stock, and redo the flashing for new u-boot.

The dockstar u-boot will enable the booting to stock OS on NAND. But it might cause some lack of capability such as SATA. OTOH, it is OK to run the Pogo V4 stock rootfs with Dockstar u-boot, since we dont care much about full capability, we just want to go into rescue mode.


OK. The summary: Boot into Debian on this Pogo V4 with new u-boot and Debian rootfs on USB/MMC/SATA. Attach the ubi device and mount it. And then copy the Dockstar original u-boot to the root folder of this volume.

Once you done the booting, please post the entire serial boot log (or at the minimum, dmesg output) here. So I can see everything before I post the commands to mount UBIFS.

OK, I'm definitely unfamiliar with mtd, ubi and ubifs, so please take pity on me, but this is what I tried:

root@debian:~# grep ubi /proc/filesystems
nodev ubifs
root@debian:~# modprobe ubi mtd=4
root@debian:~# mkdir /mnt/ubi4
root@debian:~# mount -t ubifs ubi4 /mnt/ubi4
mount: unknown filesystem type 'ubifs'
root@debian:~#

The only ubi I see in /dev is /dev/ubi_ctrl. Should there be /dev/ubi0, ubi1, etc?

root@debian:~# ls -l /dev/ubi*

Hi Ralph,

First you would attach the ubi_ctrl device to mtd 4. This will give you ubi0.

ubiattach /dev/ubi_ctrl -m 4

And then, mount its volume (root) to a folder

mkdir -p /tmp/pogo_root
mount -t ubifs ubi0:root /tmp/pogo_root

Explanation:

You did not see ubi0 in the syslog, because it was never attached. This happens automatically during boot if the kernel knows that you have a ubi control device. And that should be in the bootargs (but our bootargs env does not specify anything about UBI, since UBI is box-specific).

No ubiattach command, so had to install mtd-utils.
Then tried the ubiattach, but get an error 22

root@debian:~# ubiattach /dev/ubi_ctrl -m 4
ubiattach: error!: cannot attach mtd4
error 22 (Invalid argument)

Tried doing the modprobe first, but same error

root@debian:~# modprobe ubi mtd=4
root@debian:~# ubiattach /dev/ubi_ctrl -m 4
ubiattach: error!: cannot attach mtd4
error 22 (Invalid argument)

ubiattach -h shows this help info:

root@debian:~# ubiattach -h
ubiattach version 2.0.0 - a tool to attach MTD device to UBI.

Usage: ubiattach [<UBI control device node file name>]
[-m <MTD device number>] [-d <UBI device number>] [-p <path to device>]
[--mtdn=<MTD device number>] [--devn=<UBI device number>]
[--dev-path=<path to device>]
[--max-beb-per1024=<maximum bad block number per 1024 blocks>]
UBI control device defaults to /dev/ubi_ctrl if not supplied.
Example 1: ubiattach -p /dev/mtd0 - attach /dev/mtd0 to UBI
Example 2: ubiattach -m 0 - attach MTD device 0 (mtd0) to UBI
Example 3: ubiattach -m 0 -d 3 - attach MTD device 0 (mtd0) to UBI
and create UBI device number 3 (ubi3)
Example 4: ubiattach -m 1 -b 25 - attach /dev/mtd1 to UBI and reserve
25*C/1024 eraseblocks for bad block handling, where C is the flash
is total flash chip eraseblocks count, that is flash chip size in
eraseblocks (including bad eraseblocks). E.g., if the flash chip
has 4096 PEBs, 100 will be reserved.

-d, --devn=<number> the number to assign to the newly created UBI device
(assigned automatically if this is not specified)
-p, --dev-path=<path> path to MTD device node to attach
-m, --mtdn=<number> MTD device number to attach (alternative method, e.g
if the character device node does not exist)
-O, --vid-hdr-offset VID header offset (do not specify this unless you really
know what you are doing, the default should be optimal)
-b, --max-beb-per1024 maximum expected bad block number per 1024 eraseblock.
The default value is correct for most NAND devices.
Allowed range is 0-768, 0 means the default kernel value.
-h, --help print help message
-V, --version print program version

So tried -p option with same result

root@debian:~# ubiattach -p /dev/mtd4
ubiattach: error!: cannot attach "/dev/mtd4"
error 22 (Invalid argument)

and even tried with both ubi control device and -p option

root@debian:~# ubiattach /dev/ubi_ctrl -p /dev/mtd4
ubiattach: error!: cannot attach "/dev/mtd4"
error 22 (Invalid argument)

Sure looks like one of these would be valid. Any thoughts?

Here is dmesg from my various attempts

Ralph,

mtd4 is probably corrupted.

Try to see if you can attach mtd3:

ubiattach /dev/ubi_ctrl -m 3
ubinfo -a

And you don't need to modprobe it because UBI/UBIFS was configured into the kernel.

I was able to do ubiattach for mtd3

Quote

root@debian:~# ubiattach /dev/ubi_ctrl -m 3
UBI device number 0, total 64 LEBs (8257536 bytes, 7.9 MiB), available 40 LEBs (5160960 bytes, 4.9 MiB), LEB size 129024 bytes (126.0 KiB)

But I still get the "unknown filesystem type 'ubifs' error. (I just reused /mnt/ubi4 directory I'd created before)

Quote

root@debian:~# mount -t ubifs ubi0:failsafe /mnt/ubi4
mount: unknown filesystem type 'ubifs'

Now here is the interesting thing. I CAN boot my other Pogo to original OS (it is running the 2014 U-boot), so I know its root filesystem is OK, but I can't ubiattach it either

Quote

root@pogoplug:~# ubiattach /dev/ubi_ctrl -m 4

Can I just dump /dev/mtd4 on this pogo (which does have uboot.mtd0.dockstar.original.kwb in its root) with dd and write it to the other one?

Interesting indeed! perhaps it is incompatibiltity issue, not corruption. I have not looked into this because there are many other solution for rescue systems. See the Wiki,

Definitely. But you want to use nanddump, not dd. Again in the Wiki,

Yep, -n is same as --noecc, and it appears that --omitoob is default.
The only oob options it gives are -oob and -onlyoob

The bootcmd_exec I posted previously looks correct, right?

Quote

bootcmd_exec=if run load_uimage; then if run load_initrd; then if run load_dtb; then bootm $load_uimage_addr $load_initrd_addr $load_dtb_addr; else bootm $load_uimage_addr $load_initrd_addr; fi; else if run load_dtb; then bootm $load_uimage_addr - $load_dtb_addr; else bootm $load_uimage_addr; fi; fi; else run bootcmd_pogo; fi

I put it in /boot/uEnv.txt on my debian root partition and rebooted to insure debian still boots OK (it did). But of course I have to set it with fw_setenv for it to actually boot the old imbedded OS, and want to make sure I don't brick it such that it won't boot either one.

Also, if I'm understanding it correctly, /proc/mtd shows erasesize of 00020000, or 128K. So, since this is a 112Mb partition, do I use block count of 896, i.e.

flash_erase /dev/mtd4 0 896

The bootcmd_exec change above looks OK. But don't use uEnv.txt. Because the idea with rescue boot is that when the rootfs drive is corrupted, or not present, it will boot into stock OS on mtd4.

So test it with serial console only by setting bootcmd_exec and then boot.

setenv bootcmd_exec 'if run load_uimage; then if run load_initrd; then if run load_dtb; then bootm $load_uimage_addr $load_initrd_addr $load_dtb_addr; else bootm $load_uimage_addr $load_initrd_addr; fi; else if run load_dtb; then bootm $load_uimage_addr - $load_dtb_addr; else bootm $load_uimage_addr; fi; fi; else run bootcmd_pogo; fi'

boot

And then after a few successful tests, you would boot into Debian and set it permanently:

fw_setenv bootcmd_exec 'if run load_uimage; then if run load_initrd; then if run load_dtb; then bootm $load_uimage_addr $load_initrd_addr $load_dtb_addr; else bootm $load_uimage_addr $load_initrd_addr; fi; else if run load_dtb; then bootm $load_uimage_addr - $load_dtb_addr; else bootm $load_uimage_addr; fi; fi; else run bootcmd_pogo; fi'

Use the parameter 0 to tell flash_erase you want to erase the whole partition (flash_eraseall was deprecated):
flash_erase /dev/mtd4 0

Re: Switch from Archlinux to debian

OK, "flash_erase /dev/mtd4 0 0" worked, thanks.

I don't currently have a serial console on this device. But here's what I was thinking re: /boot/uEnv.txt:

The first thing bootcmd runs is bootcmd_uenv, so after that completes, bootcmd_exec should be set to what is in uEnv.txt. If so, then if the pogo successfully boots (it does), then at a minimum that bootcmd_exec will successfully boot debian. Then set bootcmd_exec with fw_setenv and remove /boot/uEnv.txt. Power down, remove SD card, and see if it will boot to the old CE OS. If not, power off, put SD back in, and it should at least still boot to debian, and I can try to figure out why old OS didn't boot.

Assuming I set with fw_setenv to EXACTLY what was in uEnv.txt, it shouldn't brick it, Do you see any errors in that logic?

[10/22/20 update]
OK, I decided to try something that I can easily undo. I put this in /boot/uEnv.txt to see if it would boot the old Pogo OS.

bootcmd_exec=run bootcmd_pogo.

and bootcmd_pogo is set to this:

root@debian:~# fw_printenv bootcmd_pogo
bootcmd_pogo=if ubi part root 2048 && ubifsmount ubi:rootfs && ubifsload 0x800000 uboot.mtd0.dockstar.original.kwb ; then go 0x800200; fi

When I rebooted, it never made it past blinking-green, and my router didn't show it being up on the network. Changed back to previous proposed value for bootcmd_exec and debian booted fine.

Hmmm.... Theoretically that should have worked, yes?

I enabled netconsole and tried booting with "bootcmd_exec=run bootcmd_pogo" in /boot/uEnv.txt again. This is what I see in the console log (I stripped out 900+ of the "ubi0: fixable bit-flip detected at PEB ###" errors to keep this post a little smaller

Last thing it does before the errors is attach mtd1, but 894 is the number of blocks I wrote to /dev/mtd4 with nandwrite, so is mtd4 where the problem is? I pulled up my command history and this is what I ran:

nandwrite -n /dev/mtd4 mtd4.pogo_v4

Cool, netconsole is all you need.

That mtd1 being attached is not accurate. It really tried to attach mtd4.

At netconsole prompt, execute

setenv partition nand0,4
and then

mtdparts
You should see which mtd is active.

And then switch between partitions to see if they are OK.

ubi part failsafe
mtdparts

ubi part root
mtdparts
