Hi Nicolas.A,

  1. For debugging via UART on the Apalis iMX8 8QM, there are indeed dedicated pins that you should use. It is essential to refer to the hardware documentation to accurately identify these pins, as they are crucial for establishing a reliable UART connection during debugging sessions.

  2. Yes, it is possible to program the Apalis iMX8 8QM board via USB. You will need to use the appropriate USB port designated for programming. Additionally, specific pins may need to be configured to enter programming mode through the USB port. The exact USB port and the necessary pin states for this configuration are typically detailed in the hardware documentation. Consulting this documentation will ensure successful programming of the board.

If you need further assistance, feel free to ask!

Sincerely,
[Your Name]
