PogoPlug Mobile - Stuck at "booting the kernel."

PogoPlug Mobile - Stuck at "booting the kernel."
September 22, 2017 12:49AM
Having flashed the 2016.05-tld-1 uboot without incident I followed the directions from bodhi's excellent thread (Bodhi's Linux Kernel Kirkwood Thread) but my board simply refuses to boot. It seems to load the kernel and initrd from my flash drive fine and the checksums come back OK, but after it reaches the message "booting the kernel." it just stops.

I have tried this several times with different flash drives and I have observed the same behavior in all cases. The system just hangs with both the red and green LEDs on and no further output occurs on the serial console, nor does the disk access light blink on the flash drive.

Ultimately my goal is to be using a different distribution than Debian (if anyone has info on what makes the kirkwood kernels special I'd love to know it, I'd much rather boot a clean upstream kernel if possible), but I figure the most direct way to get there at the moment is to boot Debian and then swap out the userland before ultimately going the full custom image route. Of course if I can't boot at all I won't be making much progress!

Thanks in advance for any advice anyone might have.

UPDATE: Some more poking and I get some more info. On some boots I will get various messages like this:
EHCI timed out on TD - token=0x1e008d80

The hex address changes between a handful of values and then it may boot after a few minutes. It seems to be random if this happens or not. I also get this message on some attempts:

 ** ext4fs_devread read error - block

The furthest its gotten so far is a kernel panic due to /dev/sda1 being unavailable. I suspect that this may be due to a bad image, but the drive comes up clean on my desktop and fsck reports no errors. The EHCI errors make me think that the timing might not be totally correct on the drive, but I have insufficient tooling to confirm this. I have these errors both with name brand drives and with cheap drives. I can procure a brand new drive to try this with if its likely the drive at fault.

For completeness, here is the boot log on the most successful attempt so far: https://hastebin.com/bonawimolu.vbs. Note that I had to run on early debugging to see any of that output, it was otherwise as described above with no output.

Do you have a serial console log that you can post here? (from this info, you definitely have serial console or netconsole). The log should be from the u-boot banner until it stops booting. This is quite common, so hopefully I can point out the problem in setting up.

In either serial console or netconsole, interrupt console and print out the env before letting it continue to boot:

printenv
boot

This usually indicated just that, the kernel stopped booting and stuck at that state where the LED light never get to set to green (solid green = at the point where kernel has successfully booted, and before the rootfs was mounted successfully).

It is entire possible to boot another distro using a mainline rootfs for this box. Just that the Pogo Mobile is not supported upstream, so most users use my released Debian rootfs and kernel for this box.

Which one do you have in mind? perhaps I could make an educated guess and save you some research time.

Yes, that's how to do it. Sounds like you have thought about the steps. You could run a mainline rootfs from any "easy to switch" distro such as Arch, Fedora, Ubuntu, Gentoo. But booting Debian first is a prudent approach, because it eliminates a lot of unknowns.

As long as you have an armv5 rootfs for the other distro already running in another ARM box, usually you can switch easily.

Looks like we are posting at the same time :)

I've looked at the log and glad to see you have serial console.

This is an easy problem to solve after I see your listing of the envs in serial console.

Indeed it looks like I was editing as you were typing.

I am inclined to believe that these older drives I have may be having problems talking to the USB controller on the board. If that is the case, I believe this may be easier to troubleshoot running from an SD card than a USB key. What do you think?

As far as choice of distro, I'm one of the people behind Void Linux, so it was reasonably trivial for me to spin up a build for a complete base filesystem in the armv5 flavor. We actually have the kirkwood kernel from the ALARM project packaged, but I was hopeful to use a mainline kernel. Taking a closer look at the kirkwood-kernel package though it does seem that it requires jumping through some hoops to get it to boot, so I think I'll just bring Void's kirkwood-kernel package up to date instead.

USB is much better. If you have Sandisk brand, it's the most reliable for booting Kirkwood boxes.

But looking at you bootargs, it is the wrong one.
[    0.000000] Kernel command line: console=ttyS0,115200 root=/dev/sda1 rootdelay=10 rootfstype=ext3 mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)

So you did step 4 in the rootfs creation?

Quote

4. Create uImage with embedded DTB for booting with older u-boots (2012 or earlier). Skip this step if you have installed the latest U-Boot for Kirkwood (or are installing this u-boot at the same time).

With the new u-boot, you should not do step 4. The original uImage must be used.

That would be best. And then all you need to do is to use my released kirkwood-pogoplug_v4.dtb to boot Void Linux. If it is successult, then take the source DTS and compile it in your environment to make sure it is consistent.

Yes, I did step 4 in the instructions, though I do not believe it is making it as far as that in booting. Per your request, here is the bootlog:

maldridge,

The current envs setting is from old u-boot. You did not flash the default envs image when you installed U-Boot 2016.05-tld-1.

Quote

8. Flashing default u-boot envs image:

As described in step 1, u-boot envs must be defined in etc/fw_env.config as

# MTD device name Device offset Env. size Flash sector size Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000

A special section (B. Flashing default u-boot envs image) about flashing default u-boot envs is included at the end of this installation procedure. Please follow the instruction in this section B to perform this step before continuing with step 9.

That explained why it booted with the uImage with DTB embedded in step 4. And because of that, the bootargs was the one from the DTB.

In the next post I will post a temporary fix.

I might have missed your point here! Did you mean the mainline kernel, not one from Arch?

Success!

I was able to use your shim values to boot into the flash drive and from there write the correct variables back out to u-boot.

Yes, I was referring to booting with an upstream kernel as obtained from kernel.org and cross compiled for armv5. I have such a kernel for 4.13.1, but I could not get it to go further than the "booting the kernel". You mentioned that the upstream kernels don't support the kirkwood architecture, but they do include a "kirkwood-pogoplug-series-4.dtb" file in the dtbs, perhaps you can shed some light on this?

No, I did not mean that the mainline kernel does not support kirkwood. In fact it does support several kirkwood boxes such as dockstar, pogo V4, sheevaplug. What I meant was most of the time, the kirkwood boxes that have DTS in upstream don't take full advantage of the kirkwood boxes. So users usually come here or to Arch site to get the downstream kernel.

For your Pogo V4 Mobile boxes, you could install the upstream kernel, and then use either upstream version or my version of the DTS (either copy the DTB as is, or compile the DTS using my patch). Then you 'll be all set!

For a majority of Kirkwood boxes they are not in maintsream, so you would have to experiment by running a vanilla Kirkwood kernel, and then use my DTB in the Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2 rootfs. If successful, you can copy the DTS from the patch in kernel tarbal
linux-4.12.8-kirkwood-tld-1-bodhi.tar.bz2 and compile it in your environment.

Since you can boot Debian successfully now, it's just a matter of using a right DTB to boot your Void Linux amrv5 rootfs :) some u-boot envs might need adjustment (because the Void Linux rootfs might be organized differently from Debian rootfs).

I'll be glad to help you getting it booting. If you are not sure about something, post the serial bootlog, and the file structure of Void Linux rootfs (such as where is the kernel image, initrd, ad DTB).

Thanks!

I made some progress today (I just didn't check back here until now). Basically what I'm looking at for the moment is that Void's default kernel builds export a zImage. I can alter this to be a uImage containing a zImage, but since your more modern uboot seems to support booting the zImage directly I'd much rather do that.

Ultimately I've got the following:
/boot/zImage
/boot/uInitrd
/boot/dtbs/kirkwood-pogoplug-series-4.dtb

The rest of the system is a reasonably standard FHS compliant Linux chroot and it expects to come up via a call to /sbin/init, I expect that this will be a mostly standard boot once the initrd and kernel are loaded, but I'm struggling a bit to figure out which variables in u-boot should be modified to hunt for a zImage instead of a uImage.

So I guess my next steps hinge on whether or not the zImage format is sufficiently stable to boot with or if I'm better off repackaging the zImage archive into a uImage.

We should be able to boot the zImage and these kernel files.

It is best that I can see your current envs in u-boot prompt to show you how to change them to use bootz.

-----

However, as an example, assuming you have not changed u-boot envs to the default envs. These envs are what we had before for temporary booting previously:
setenv bootargs_usb 'console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 earlyprintk=serial'
setenv usb_load_dtb 'ext2load usb $device 0x1c00000 /boot/dts/kirkwood-pogoplug_v4.dtb'
setenv usb_boot 'mw 0x800000 0 1; run usb_load_uimage; run usb_load_uinitrd; run usb_load_dtb; bootm 0x800000 0x1100000 0x1c00000'
printenv
boot

We can change these envs to boot zImage. The differences are: use bootz instead of bootm, and since you want to use the mainline DTB. The boot commands will be

setenv bootargs_usb 'console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 earlyprintk=serial'
setenv usb_load_image 'ext2load usb $device 0x800000 /boot/zImage'
setenv usb_load_dtb 'ext2load usb $device 0x1c00000 /boot/dtbs/kirkwood-pogoplug-series-4.dtb
setenv usb_boot 'mw 0x800000 0 1; run usb_load_image; run usb_load_uinitrd; run usb_load_dtb; bootz 0x800000 0x1100000 0x1c00000'
boot

Ramdisk image is corrupt or invalid

Given that this is a clean build I'm not really that inclined to say it could be corrupt, but I'm very certain it could be built incorrectly. That ramdisk is built with the following command:

env -i /usr/bin/mkimage -A arm -O linux -T ramdisk -C none -a 0 -e 0 -n 'Void Linux' -d /boot/initrd /boot/uInitrd

All the examples I've seen say that I can just use null addresses for the ramdisk, but maybe that's not quite right?

Ah!

1. Couple more env needs to be adjusted

setenv load_image_addr 0x800000
setenv scan_disk 'echo running scan_disk ...; scan_done=0; setenv scan_usb "usb start";  setenv scan_ide "ide reset";  setenv scan_mmc "mmc rescan"; for dev in $devices; do if test $scan_done -eq 0; then echo Scan device $dev; run scan_$dev; for disknum in $disks; do if test $scan_done -eq 0; then echo device $dev $disknum:1; if load $dev $disknum:1 $load_image_addr /boot/zImage 1; then scan_done=1; echo Found bootable drive on $dev $disknum; setenv device $disknum:1; setenv bootdev $dev; fi; fi; done; fi; done'

setenv dtb_file '/boot/dtbs/kirkwood-pogoplug-series-4.dtb'
setenv load_image 'echo loading Image ...; load $bootdev $device $load_image_addr /boot/zImage
setenv bootcmd_exec 'run load_image; if run load_initrd; then if run load_dtb; then bootz $load_image_addr $load_initrd_addr $load_dtb_addr; else bootz $load_image_addr $load_initrd_addr; fi; else if run load_dtb; then bootz $load_image_addr - $load_dtb_addr; else bootz $load_image_addr; fi; fi'
boot

2. Your uInitrd is way too big. So there is something wrong there. The ramdisk was corrupted because it was overwritten by the DTB loading at 0x1c00000.

This is how we generate the uInitrd for Debian

cd /boot

This indicated that you did not use compression.
env -i /usr/bin/mkimage -A arm -O linux -T ramdisk -C none -a 0 -e 0 -n 'Void Linux' -d /boot/initrd /boot/uInitrd

Also check the size of your initrd. My initrd is quite large compare to others, and it is only 6.8M. Is there things other than kernel modules in your initrd?

Nope, nothing but kernel modules in there and a handful of binaries to bring the rest of the system up. Now I should mention that for some reason it has every possible module that can be built for armv5, but that's besides the point...

I'll sort this out so that it has a more reasonable number of modules and try again.

Nope, no desktop software, just a lot of modules: https://hastebin.com/zacoveraqe.diff

I think I can safely get rid of (at a high level) the following modules:
* drm
* resume
* i18n
* terminfo

That should slim it down some, and removing kernel modules that shouldn't be loaded will get it the rest of the way. I could probably remove the btrfs modules as well, but since those are part of Void's base system package, that would be a bit of a hack.

OK. Sounds good. However, if it's too much works to get to a good size (< 20M), we''ll adjust the load address of the DTB to be way up, to get all 3 images loaded. U-Boot will take care of the actual reallocation before booting.

For good measure I turned on the serial printk, but it seems to just sit there and the disk access light is off. I have a build running with your kernel config and I will see if that fixes anything tomorrow evening. I can also just try to use the debian kernel directly and see if it boots further with that.
Re: PogoPlug Mobile - Stuck at "booting the kernel."

When it is stuck like this without serial printk output, the kernel image could have been corrupted.

Starting kernel ...

Note that this kernel file is also quite big (~7M).

1. Since we have moved the DTB to lower memory, you could move the uInitrd out further, such as

setenv load_initrd_add  0x2100000

2. Or try booting with uImage instead of zImage. And then after it's working, switch to zImage.

Re: PogoPlug Mobile - Stuck at "booting the kernel."

Success!

I rebuilt the kernel using an updated version of your .config and it now boots happily. I have some cleanup work to do and then I will write-up the process in case someone else wants to get Void running on similar hardware. Needless to say there will be a shoutout to you in there!

For completeness, here's the boot log and some commands that give an idea of what the default system looks like straight out of the build. Ultimately I think I will go with muslc so that I can ditch the locales and try to fit inside the NAND footprint, though an SD card will work fine for now. Screen seems to have truncated the boot log a bit, the commands to boot are exactly those shown above. I will try to get a complete banner-to-login log later.
