Good afternoon. Thanks for the help. New problem. When debugging a project on STM32MP157A-DK1 in engineering mode, the program sends a request via COM3 instead of a request via STlinck(OpenOCD). See the photo. Sincerely, Alexander.

Hi @Vlaty.1​ 

Your screenshot looks normal.

ST-Link connection is also providing a Virtual COM port seen as COM3 on your PC.

But you can noticed the display is grey highlighting this is not taken into account for JTAG/SWD link (Engi mode)

Are you facing issues while debugging ?

Good afternoon, Oliver. Thanks for the help. I know why ping doesn't work. There is no ping driver in the linux net directory. Sincerely, Alexander.:grinning_face: пт, 18 �?ент. 2020 г. в 11:04, ST Community :
