#yocto update the kernel with a rauc bundle

#yocto update the kernel with a rauc bundle

[Hans-Ulrich Schlieben]

[-- Attachment #1: Type: text/plain, Size: 785 bytes --]

Hi,

i have a working configuration with images and rauc bundles. My problem is that kernel and devicetree are located outside the rootfs and so a bundle update never includes these.
My image.wks looks this:
part BAREBOX --source rawcopy --sourceparams="file=barebox.bin,skip=1024" --ondisk mmc --no-table --align 1
part   --source bootimg-partition --fstype=vfat --label boot --ondisk mmc --active --align 4096 --size 20
part / --source rootfs            --fstype=ext4 --label rootA --ondisk mmc --align 1024 --use-uuid --fixed-size 700
part / --source rootfs            --fstype=ext4 --label rootB --ondisk mmc --align 1024 --use-uuid --fixed-size 700

How do i move kernel and devicetree into /boot?

Any help would be greatly appreciated. Thank you

hu

a RAUC bundle can contain images for multiple partitions / slots.
You just have to specify them in your system.conf to make them updatable.

An

IMAGE_INSTALL_append = " kernel-image kernel-devicetree"

, for example in your image recipe, should do the trick.

When using barebox you have full bootspec support thus you probably als
want to place a bootspec entry in /loder/entries to automate loading the
right kernel and dtb. A helper class is here:

Hi Enrico,

I just answered your first mail on the website and thought that will automatically reply to all. Added all lists now, hope these are correct.

Thanks to you I found the custom automount in the providers recipes. This mounts /dev/mmc0.0 to /mnt/mmc.
After the mount it seems that only when I install a new image the barebox mount /dev/mmc0.0 to /mnt/mmc0.0 works. 
Rauc / barebox seems something to change after a bundle update whereas mount /dev/mmc0.0 to /mnt/mmc0.0 fails and the files are only visible in /mnt/mmc.

/mnt/mmc works in both cases so I have now 
/mnt/mmc/boot... for system0 and
/mnt/mmc0.1/boot... for system1

Best regards

hu

Hi hu,

please keep at least any list in CC so that others can benefit from this discussion, too (Both RAUC and barebox ML would fit here). It also increases the range and thus potential people that may help here.

Which version of barebox?

It should be sufficient to either say

  boot mmc0.0

or

  boot mmc0.1

and barebox will automatically mount the partition, look for a bootspec file under /loader/entries and assemble the required boot options and kernel command line automatically.

Is there any custom automount unit located in you built-in env probably?

Ok, good that we clarified this. The script should not be required in a
modern barebox as it has a lot of built-in automounting magic on board.

This is the point that sounds a little strange, yes.

Would be great to see a log of such a failed mount to get a more
concrete idea what 'failed' actually means.

Hi Enrico,

the boot log looks like this:

-> booting mmc0.1 works

So the problem is that barebox mounts /dev/mmc0.0 on /mnt/mmc and not on /mnt/mmc0.0. But what configuration tells barebox to mount
/dev/mmc0.0 on /mnt/mmc
and
/dev/mmc0.1 on /mnt/mmc0.1?

The configuration parameters are this: 
* bootchooser.system0.boot: mmc0.0
* bootchooser.system1.boot: mmc0.1
* bootchooser.targets: system0 system1

Re: [RAUC] Private: Re: [yocto] #yocto update the kernel with a rauc bundle

[Hans-Ulrich Schlieben]

Hi Stefan,

same result without the automount files. 
I'm not really shure whether I built barebox the intended way. What I did was to add RM_WORK_EXCLUDE += " barebox" to local.conf,
Rebuild barebox with bitbake -c cleansstate barebox, removed the three automount files below the imx6 folders and run 
bitbake -f -c compile barebox
and built the image. Did this disable the automount?

Best regards

hu

Re: [RAUC] Private: Re: [yocto] #yocto update the kernel with a rauc bundle

[Hans-Ulrich Schlieben]

Hi Stefan,

thank you for your help.

automount changed from formerly 

/mnt/eeprom0.update-eeprom mount eeprom0.update-eeprom
/mnt/mmc0            mount mmc0
/mnt/mmc0.0          mount mmc0.0
/mnt/mmc0.1          mount mmc0.1
/mnt/mmc0.2          mount mmc0.2
/mnt/mmc0.3          mount mmc0.3
/mnt/mmc0.barebox    mount mmc0.barebox
/mnt/mmc0.barebox-environment mount mmc0.barebox-environment
/mnt/tftp            ifup eth0 && mount -t tftp $eth0.serverip /mnt/tftp
/mnt/mmc             mmc0.probe=1 && [ -e /dev/mmc0.0 ] && mount /dev/mmc0.0 /mnt/mmc
/mnt/emmc            mmc3.probe=1 && [ -e /dev/mmc3.0 ] && mount /dev/mmc3.0 /mnt/emmc
/mnt/ratp            mount -t ratpfs none /mnt/ratp

to 

/mnt/eeprom0.update-eeprom mount eeprom0.update-eeprom
/mnt/mmc0            mount mmc0
/mnt/mmc0.0          mount mmc0.0
/mnt/mmc0.1          mount mmc0.1
/mnt/mmc0.2          mount mmc0.2
/mnt/mmc0.3          mount mmc0.3
/mnt/mmc0.barebox    mount mmc0.barebox
/mnt/mmc0.barebox-environment mount mmc0.barebox-environment
/mnt/tftp            ifup eth0 && mount -t tftp $eth0.serverip /mnt/tftp
/mnt/mmc             mmc2.probe=1 && [ -e /dev/mmc2.0 ] && mount /dev/mmc2.0 /mnt/mmc
/mnt/ratp            mount -t ratpfs none /mnt/ratp

so my removing of automount worked changed something. I had to remove the other automount file too to get here

/mnt/eeprom0.update-eeprom mount eeprom0.update-eeprom
/mnt/mmc0            mount mmc0
/mnt/mmc0.0          mount mmc0.0
/mnt/mmc0.1          mount mmc0.1
/mnt/mmc0.2          mount mmc0.2
/mnt/mmc0.3          mount mmc0.3
/mnt/mmc0.barebox    mount mmc0.barebox
/mnt/mmc0.barebox-environment mount mmc0.barebox-environment
/mnt/tftp            ifup eth0 && mount -t tftp $eth0.serverip /mnt/tftp
/mnt/nfs             ifup eth0 && mount -t nfs ${eth0.serverip}:/home/${global.user}/nfsroot/${global.hostname} /mnt/nfs
/mnt/ratp            mount -t ratpfs none /mnt/ratp

But the result was the same. Same log output as before, three failing boot attempts on mmc0.0 and then booting from mmc0.1. 

(I'm not shure whether i remember right that I had a config where the boot to mmc0.0 
from the image worked and the rauc update only failed to boot from mmc0.0.
Now directly the image fails too.)

Even if this failed to help just for my understanding, how could I remove / override these automount files in a recipe?

Thank you and best regards

hu
