Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
Before answering your question, I was wondering if you can introduce the testing environment, for instance, board, code, IDE, etc.
Have a great day,

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I'd like to know whether the issue happens when debugging with the MIMXRT685-EVK board.
