Dear community,
I've used yocto as my workhorse in the past a lot for other processor manufacturers. Now as I'm happily joining the STM world for linux I'm stuck. Maybe it is a too easy to miss question, but which steps I have to take for putting all the needed images to the sd-card? I have followed the rules to go for using the create_sdcard_from_flashlayout.sh script with FlashLayout_sdcard_stm32mp257f-dk-optee.tsv as the parameter. After that I've used dd to flash the .raw to the designated sdcard but the board does not start at all. From the provided sdcard it starts without any issue.
Where is my mistake?
Regards
KS
