Updating the boot partition on Raspberry using Debian (non Yocto)

dwjbosman · February 11, 2021, 12:54pm

I am using mender 2.5 and Debian on Raspberry 3B

I need to update the boot partition. I am following these steps:

Configure the golden device
Use mender-convert to create an artifact and .img
Mount the boot partition of the generated .img and copy the /uboot and /boot files into an overlay folder /boot_update/uboot, /boot_update/boot
Regenerate the artifact including the /boot_update folder
An ArtifactInstall_Leave script uses rsync to copy the /boot_update folders to /uboot and /boot
Mender performs a reboot

It doesn’t seem to work correctly.
*The kernel is updated
*For some time (several minutes) the mender server doesn’t see the device
*In the logs I don’t see the artifactinstall_leave script called
*The device boots up with a black screen and resets after sometime. As if a rollback is being performed? But in the end the device runs the updated firmware…

Should this approach updating /uboot and /boot work?

Will Mender specific configuration settings on /uboot (the active A/B partition?) be kept, or are these overwritten?

Hi @dwjbosman

Any chance you could post the logs to begin with?

Also, have a look at this, even though it is not for mender-convert, I think it is informal.

In general, /boot is mounted as a separate partition. Have a look in fstab, to make sure if it is boot, or /uboot (I think it is /uboot/ in this case).

So, in short, everything written to the boot partition is kept, as it is a separate partition.

The rest of your questions I think I need a log to look further into

Hi @oleorhagen,

I made the mistake thinking that the newly downloaded rootfs was mounted at step 5. So the script was actually rsync’ing the old/currently installed boot files…

So now the steps become:

Configure the golden device
Use mender-convert to create an artifact and .img
Mount the boot partition of the generated .img and copy the /uboot and /boot files into an overlay folder /boot_update/uboot, /boot_update/boot
Regenerate the artifact including the /boot_update folder
An ArtifactReboot_Leave script uses rsync to copy the /boot_update folders from the newly installed rootfs to /uboot and /boot
5.1. The ArtifactReboot_Leave script will need to reboot the device again so that the new kernel boots.

Is it allowed to do another reboot in 5.1. Or will mender then assume that the install failed (and try to rollback)?

Hi

For 5.1, you cannot reboot. This will mark the udpate as failed, and mender will fall back.
However, you can do a reboot in ArtifactCommit_Leave. This will do a reboot, and not roll back to the old update, as the new image is already committed.

Please give it a try, and tell me how it goes

Used the ArtifactCommit_Leave script. It includes a ‘reboot’ command.

This currently results in an error:

I will turn on debugging and retest

oleorhagen · February 12, 2021, 1:27pm

Oh, this is because of this. I’m sorry, I did not think it was also handled in commit-leave.

This means that you’re script needs to have some sort of state (like a file?), so that you will only reboot the one time

dwjbosman · February 12, 2021, 11:45pm

I used the ArtifactCommit_Leave script to do the reboot. In the script I just deleted the script, so that no multiple reboot would take place

sh update_kernel.sh
rm -f /data/mender/scripts/ArtifactCommit_Leave_02
reboot
