Programming external STM32 MCU via STM32MP1

Hi all,

Is it possible to load .elf to an external STM32 MCU at the boot time of STM32MP1?

I specifically want to target an external STM32MCU not the internal M4.

How it can be achieved?

    The serial port boot loader protocol is documented. There is an app stm32flash that implements it. The ELF object format is also documented.​
