Rpi3 and Rpi4 not booting after meta-updater layer integration to Yocto

[oferorgal]

Hello all,

After adding meta-updater and meta-updater-raspberrypi layers to yocto build, both Rpi3 and Rpi4 stopped botting from u-boot:

(UART output)

I made the changes to my yocto build manually but after this didn't work I followed the https://docs.ota.here.com/getstarted/dev/raspberry-pi.html tutorial without the "here" credentials (Also replaced advancedtelematics repo with uptane).

Note: All Yocto, meta-* branches are on dunfell.

Did support for the boards stopped at any point? Can you guide me/add to README how to make it work?
Any help would be great.
Thanks,
Ofer.

I was able to fix the problem by changing: bootcmd_run=bootm "${ramdisk_addr_r}${fit_conf}" to bootcmd_run=bootm ${ramdisk_addr_r} ${fit_conf}

Now, I have a different problem on RPi4 that I keep getting this error while the kernel boots:

Any ideas?

Are you using https://github.com/advancedtelematic/meta-updater-raspberrypi? I totally forgot we once had that repo. It was never migrated to the uptane namespace, which was probably an oversight. We wanted to combine it with dynamic layers anyway, but never got around to it.

[oferorgal]

Yes. I'm using this guide: https://docs.ota.here.com/getstarted/dev/raspberry-pi.html.

It seems that meta-raspberrypi (dunfell) and meta-updater-raspberrypi (dunfell) are not in sync.
For example, meta-raspberrypi kernel version is 5.4 and meta-updater-raspberrypi is 4.19....

Can someone point more changes between them?

Changing meta-updater-raspberrypi to 5.4 fixes the error above but I have new error:

[    3.030159] mmc0: ADMA error: 0x02000000
[    3.034307] mmc0: error -5 whilst initialising SD card
