Hello,
I am trying to use the built-in UART bootloader on an STM32H7. I have two boards: one on which the bootloader works, and one on which it cannot connect.
The board on which I cannot use the bootloader reports the following error when I try to connect with the STM32CubeProgrammer:
Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again...
The bootloader does seem to be running, but it ends up getting stuck looping over one section of code. This is the section of code it seems to be stuck in:
Is anyone able to tell me what this section of code is checking for? That would help me determine why the bootloader cannot connect.
Thank you.
