Dear All,

I am using the STM32MP257F-EV1 board with the preloaded Linux image on the microSD card. The board powers up successfully (green LED ON, red LED blinking), but Windows does not detect any STLink Virtual COM Port even after installing STM32CubeProgrammer and ST-LINK drivers. Could you please advise the correct BOOT switch settings and whether any additional driver or jumper configuration is required to enable the COM port?

Any help would be appreciated.

Thank You,

Faisal
