Hello,we are developing IoT device for which we are planning to use STM32MP135D MPU placed on our custom SoM.To do test before SoM is ready, I have obtained a STM32MP135F-DK. There are some concerns about the 'factory programming' of such device.With...

Hello @Christophe Guibout thank you for your answer and commiting to the repo.I tested it and have two concerns:To get the default partUUID (e91c4e10-16e6-4c0e-bd0e-77becf4a3582) for rootfs slot A, I have to name it 'rootfs' not 'rootfs-a' in my .tsv...

@Christophe Guibout When using STM32MP135F-DK I have a possibility to take SD card out and plug it into host PC to use create_sdcard_from_flashlayout.sh script and 'dd' to populate it.But STM32MP135F-DK is only my test/development board, and for prod...

Doing a grep: grep -r alsa meta-st-stm32mp/ I can see that alsa is added to MACHINE_FEATURES in this file:meta-st-stm32mp/conf/machine/include/st-machine-common-stm32mp.incin line:MACHINE_FEATURES = "usbhost usbgadget alsa screen ext2 pci"Maybe try r...

To add my own files I've overwritten PACKAGE_INSTALL variable of st-image-userfs, removing the examples and instead of that listing my own packages.I hope that this auto-log of my work progress will someday help someone :)

I've moved further and decided to post it here, to help others on their way.The st-image-userfs_%.bbappend filename was invalid, and that's why Bitbake was throwing an error. After changing it to st-image-userfs.bbappend I was able to reset PACKAGE_I...
