I continually get "Error: Cannot identify the device" on STM32MP157c-dk2

[SLetter]

Trying to program over ST-LINK instead of DFU. Boot0 and Boot2 are both switched away from the card edge. Here is what I am seeing:

Hi @nonesuchetter​ ,

Program MP1 MPU using STM32CubeProgrammer is possible only using DFU, SWD is not supported.

Have a look at MP1 WIKI which give many information about MP1 flashing.

Then why is it even an option? Just curious.

Hi @nonesuchetter​ ,

The SWD is kept in this use case because it is used for testing purpose. 😊
