Controlling STM32F407 bootloader (Discovery board) with another board

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

Hello @ATank.1 ,

According to that board schematics, you can drive the BOOT with a GPIO from STM32H745 as BOOT pin is exported on the P2 connector:

But you need to unsolder SB18 and R31.

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