Controlling STM32F407 bootloader (Discovery board) with another board

ATank.1 · ‎2024-10-21

Hello

I think we can control the reset and boot0 pin of F407 externally through a different board STM32H745 disco. I want to put the F407 in boot mode and send data to program the F405 through UART. Please confirm

Thanks & Regards,

Anuj

For the reset, same thing, it's exported on the P1 connector, but you need to unsolder SB1:
