Hi,

i suggest that your start with https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-EV1

Unlike STM32 MCUs, the STM32 MPUs are not flashed using JTAG/SWD, so when using STM32CubeProgrammer you must use USB (and the board should be in serial/USB DFU mode).

JTAG/SWD is only used for debug purposes (e.g. with STM32CubeIDE).

Regards.
