I applied that patch, but unfortunately no U-Boot specific output on the special debug UART of the rpi5 at all. As I have shown in my earlier email, the output ends with the „NOTICE: BL31…“ messages and there is no single line coming from U-boot at all. Also tried to add „#define DEBUG“ to the fdtdec.c file and added CONFIG_LOG=y as well as raising the maximum debug level to 9 to the U-boot build. This for some reason this does not end up in any additional U-boot debug line output on the RPi debug probe connected to the special UART of the rpi5. I even tried to connect the debug probe to the UART pins of the GPIO but also there no U-Boot debug output at all, I am afraid.

So where should that U-Boot debug output actually appear with your u-boot.bin patched version?
