I try to get my QSMP-1570 (STM32MP157) card booting a Yocto Dunfell compiled image but got problems with uImage.
Why do I get this Bad Data CRC and how can I troubleshoot it?
I have tested to change load address, entry point and where in memory it’s loaded from eMMC without luck.
I have also tried without extlinux.

Belove is output from same board with different image. This image is clean without balena and compiled by manufacture. I have tried to use same entry point, load address and so on, but with nu success.
