Subject: Help with Falcon Mode on STM32MP157C-DK2

Hello U-Boot Community,

My name is Alessio, and I’m a student working on implementing Falcon Mode for the STM32MP157C-DK2 as part of my bachelor thesis. I’m relatively new to embedded development and would greatly appreciate guidance or collaboration with someone experienced.

So far, I’ve modified U-Boot logs and built the configuration using `stm32mp15_basic_defconfig`, with the following adjustments:
CONFIG_SPL_OS_BOOT=y  
CONFIG_CMD_SPL=y  
CONFIG_SPL_SIZE_LIMIT=0xB1000  

However, I encountered an error suggesting to run `make mrproper`. I suspect this could be specific to the STM board. Has anyone encountered similar issues or successfully implemented Falcon Mode on this hardware?

Thank you for your time, and I apologize if this message doesn’t follow mailing list conventions, as this is my first post.

Kind regards,  
Alessio
