Debug Authentication on the STM32MP2257F-EV1 for ST Link

[Carson]

Hello, I am trying to set up an ST link on the Cubeprogrammer, but whenever I try it gives me an error which states: "Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication". I am able to boot it in UART but not ST link and research on how to do this has run dry. Any help on how to do this Debug Authentication would be greatly appreciated. Thanks!

Hi @Carson,

STM32MPU product does not support ST-Link for programming but only USB or UART. 

Please refer to our documentation: 

STM32MP2 boards - stm32mpu

STM32CubeProgrammer - stm32mpu
