Kernel panic - not syncing: Attempted to kill init!

Product support balenaOS
1

On our own board based on iMX7 Dual uCOM from Embedded Artists we built our own balena image with yocto using our BSP (cloudplugedge) and the balena yocto layers meta-balena, meta-rust and poky.

We built the images “resin-image” and “resin-image-flasher” with the following yocto configuration:

Build Configuration:
BB_VERSION           = "1.40.0"
BUILD_SYS            = "x86_64-linux"
NATIVELSBSTRING      = "universal"
TARGET_SYS           = "arm-poky-linux-gnueabi"
MACHINE              = "cloudplugedge"
DISTRO               = "balena-os"
DISTRO_VERSION       = "2.36.0"
TUNE_FEATURES        = "arm armv7ve vfp thumb neon callconvention-hard cortexa7"
TARGET_FPU           = "hard"
meta
meta-poky            = "HEAD:1cab405d88149fd63322a867c6adb4a80ba68db3"

meta-balena-cloudplugedge = "master:af53c7705f909af28efdcd1916b624078b2c932e"
meta-freescale       = "<unknown>:<unknown>"
meta-resin-common
meta-balena-thud     = "HEAD:2fc8e3c0534277a0ab078fbd830ef060f7828540"
meta-rust            = "HEAD:84710b341be53cc2af13ecc8ae87773cf84687bf"

After burning the whole resin-image-cloudplugedge.resinos-img onto MMC with the MfG-Tool from Embedded Artists and adding kernel and device tree file on boot partition the system boots but we get the error in the boot log:

...
ALSA device list:
  No soundcards found.

Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000100

For my understanding the init process /sbin/init (which is a symbolic link to /current/boot/init) returns unexpected with code x100. I have no chance to say why. Due to the boot log I guess systemd tries to get mount info from /proc FS but this is not mounted yet.

After burning the flasher image “resin-image-flasher” with the MfG-Tool the OS starts:

Has anyone an idea what’s the reason for this behavior. How can I achieve that the /proc FS ist mounted first?

Can you share the yocto layers so we can have a look?

Hi. Is your board able to boot from an USB thumb drive? If yes, you would only need Mfg Tools to write a bootloader to the board f it does not come with one. If your board already has a bootloader and it is able to boot from an USB drive, then you should write the flasher image to the USB drive and boot that image. The flasher image is an installer which will install balenaOS into the internal media, provided you also declare your board’s internal media such as here for example: https://github.com/balena-os/balena-asus-tinker-board/blob/master/layers/meta-balena-asus-tinker-board/recipes-support/resin-init/resin-init-flasher.bbappend

I believe these commands run from the u-boot shell will make your board boot off the USB thumb drive:

usb start
fatload usb 0:1 0x10800000 <your kernel image>
fatload usb 0:1 0x18000000 <your dtb>
setenv bootargs 'root=/dev/sda2 rootfstype=ext4 rootwait console=ttymxc0,115200n8'
bootz 0x10800000 - 0x18000000

Also, make sure you build a development image so that you can access the board over the serial connection (if available and set-up correctly - the above ttymxc0 is just an example from another board)

Hi, thanks for the reply.
Using USB boot is a nice idea for booting the flasher image having the MMC unused and available for flashing onto it.
But I believe it will not solve our problem: The 2 step way “boot flasher image -> burn with Resin init flasher service” I’ve tested by booting the flasher system via NFS-boot and manual starting the flasher service with slight modification. After successful run the new boot of the final balena image raised the same error as booting the balena image burned with Mfg tool.

Is there any functional difference in this two proceedings? Have I overlooked any step in the flasher service which have to be done by burning with Mfg tool?
Burning the final “resin-image” with Mfg tool should work in general, isn’t it? I believe the issue is in the “resin-image” itself.
I’ve build a development image and have access to the board over the serial interface but in case of kernel panic this does not help …

Hi,

Could you please paste the full boot log?

Hi Andreas,

I found your problem. In the kernel command line: Kernel command line: console=ttymxc0,115200 root=/dev/mmcblk2p2 rootwait rw brcmfmac.sdio_wq_highpri=1.

The root parameter should be of type root=PARTUUID=9fb1643b-02 and not root=/dev/mmcblk2p2.

This means that you are lacking the Balena u-boot intergration patches. If you do have these patches applied then it means that the u-boot doesn’t run the Balena commands.

This is how the Balena u-boot patches look like:

18

Thanks, for the response but it does not solve the problem.
I’ve identified the PARTUUID used for the Partition 2 of the Balena Image and manual booted the system on u-boot prompt.
The kernel cmdline is now:

Kernel command line: console=ttymxc0,115200 root=PARTUUID=a37d30bb-02 rootwait rw brcmfmac.sdio_wq_highpri=1

This results in the same error behavior as reported:

Freeing unused kernel memory: 1024K
2000/01/01 12:00:28 could not get mounts:open /proc/self/mountinfo: no such file or directory
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000100

To verify the correctness and effectiveness of the used PARTUUID I did two more tests:
1.) PARTUUID=a37d30bb-01 – that is the BOOT partition and must raise an error
→ boot log

ALSA device list:
No soundcards found.
List of all partitions:
0100 65536 ram0

No filesystem could mount root, tried:

fuseblk

2.) PARTUUID=a37d3000-02 – wrong disc ID → non existent partition

ALSA device list:
No soundcards found.
Waiting for root device PARTUUID=a37d30aa-02…

Your mentioned patch for the yocto build I’ve not applied since I manually boot the board for test purposes

20

Dear balena team, do you have any other ideas how to get this resolved? We are stuck.
Thanks a lot!

Hi, I’m facing the exactly same issue while porting to STM32MP157. I did every U-Boot patches (I believe) mentioned here, but init still complains there is no /proc/self/mountinfo.

Here is my full boot message after firing U-Boot booting command:

I think it is not the problem of U-Boot env/config. If it was the root path problem the kernel won’t find init program at the beginning.

Any progresses on this issue?

@andreas @matthias I think I figured it out.
We should’ve check if a correct initramfs image is used. (zImage, uImage…)
It might be yocto/vendor default initramfs, not kernel-image-initramfs with resin-specific patches.

As we can see from the full boot logs, the kernel goes straight to mounting root and run /sbin/init (mobynit in this case). However, if it was the correct resin’s initramfs it must have run initrdscripts such as fsck,rootfs,finish before running /sbin/init.

The vendor default bitbake scripts might override the resin initramfs, so check your bitbake configuration. As a note the correct resin initramfs is still installed in {resin-rootA partition}/current/boot/zImage (you need to be root user to see this), so compare it with your {resin-boot partition}/zImage using md5sum.

Hi all, is this issue solved given the latest comments here?

25

I am also having the same /proc/self/mount problem
Can you help me with that

26

Did you solve this?
