Hi, I'm new to yocto project, I'm trying to bitbake  core-image-minimal image in yocto in stm32mp157d-dk1(scarthgap) ,by editing the bblayers.conf and local.conf in image, its successfully build and flashed into SD card , but I'm trying to boot device then it failed. I found in bootfs sector there was no files in it. I tried to build with kirkstone branch and it worked well, and then I tried to bitbake with scarthgap again and again. I used Ubuntu 24.04 and Linux mint 22.03, but scarthgap branch had the same problems.I wanna know the reason. BIG THX.

I have also built core-image-minimal according to the instructions and without making any changes at all to the default files, and I’m getting exactly the same error as you: no files in boot partition. I’ve tested on both boards 215F-DK and 257F-DK, and flashed using STM32_Programmer_CLI and raw mode. I’ve also tried many different TSV files, but nothing helps. So it seems to be a general issue in the Distribution-Package build environment.
I’d appreciate it if anyone has a suggestion for a solution.

Use kirkstone branch will solve this problem but it is not newest branch.
