I am interested in embedding the H7 plus in a project where there is no access to the USB port or the SWD interface. Is it possible to use the STM32H743 bootloader over one of the available UARTs (e.g., UART1, using PB14/15) to update the firmware on the H7 plus?
The STM32 line of processors can boot over a UART when BOOT0 is pulled high. You can also edit our bootloader to do this. However, you are on your own.
