    Is this part of your production test?

    What exactly has failed?

    Hi,

      What type of communication is used (e.g. UART, SPI or etc)?

      Can you show a probe capture of the signals on a known good board vs the failure board?

      On the failure board, can you toggle these pins as in GPIO mode?

      Can you do a ABA swap test? Will failure follow the MCU? 

    The A-B-A Swap Method is a simple cross check test, which can confirm the observed issue is not systemic.

    • A-B-A Swap Method
      (1) Remove the suspected component (A) from the original failing board.
      (2) Replace the suspected component (A) with a known good component (B) and check if the original board now works properly.
      (3) Mount the suspected component (A) to a known good board and see if the same faliure occurs on the good board.
