When the board booted and CN15 usb connected with PC , I found the device manager show the "Android aosp on stm32mp257f-ev1".When CN21 usb connected with PC, device manager shows up nothing new at all

Hi, @faye_Lee 

If terminal is available (I'm sure for OpenSTLinux on EV1, Android should be same I assume), it should be available in one of the two virtual COM ports which should appear on the PC when connected to the ST-Link USB CN21.

 

Some help regarding terminal here (shown when running OpenSTLinux): https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP2_boards/STM32MP257x-EV1/Let%27s_start/Execute_basic_commands

Hi PatrickF,

    When I first boot the board, there were two virtual COM ports  appeared on the PC when connected to the ST-Link USB CN21 (STM32MP257-EV1's defualt image is OpenSTLinux?). But the second time I booted the board, there were  no virtual COM port  appeared on the PC. And then I flash the Android image on it, and it has no virtual COM port too. I wonder if my STM32MP257-EV1 board has some issue? How can I verify my STM32MP257-EV1 board whether work in normally status or not? Should I flash the default OpenSTLinux image? How can I flash the default OpenSTLinux image.

Hi,

Board STLINK virtual COM ports are completely independent of flashed image (it could be seen as an external Serial<->USB converter, like it is for an external ST-LINKV3-SET). They work as soon the USB is connected and recognized correctly as a valid USB. 

Maybe check your USB cable (sometimes, there is USB charging cables without data lines).
