STM32MP157F-DK2 failing to boot on custom image

[Joel]

I'm targeting:

openstlinux-5.15-yocto-kirkstone-mp1-v22.07.27

DISTRO: openstlinux-eglfs

MACHINE: stm32mp15-disco

Image+SDK build fine. I create the raw file as usual, image SD card, and boot fails with:

I have no troubles using dunfell release with machine `stm32mp1-disco`.

My kirkstone CI (fails to boot):

https://github.com/meta-flutter/meta-flutter/blob/kirkstone/.github/workflows/kirkstone-stm32mp15.yml

My known working

dunfell CI (works):

https://github.com/meta-flutter/meta-flutter/blob/dunfell/.github/workflows/dunfell-stm32mp15.yml

Running the STM1 starter images of the same variant does work. So something about the image config.

Any ideas?

Hello @Community member​ ,

Thank you for your contribution !

Regarding your logs, TF-A has troubles with the metadata check for FWU as explained in this article.

However, i see that you updated your .yml file between Dunfell and Kirkstone with taking this into consideration with copying arm-trusted-firmware/metadata.bin too.

I will investigate and try to reproduce from my side, I will let you informed.

Kind regards,

Erwan.

It was the missing metadata.bin file. I had made my tests prior to adding the metadata.bin copy. The STMProg tool was failing looking for metadata.bin, so I had copied it for that; not realizing I just solved the problem.

Thanks for looking!
