I come across Dead loop when the program come into interrupt D2DINTCH3.
The preconditon is that I connect with nothing only a bare board.
Could you help me clarify the question?
Thank you for writing
It is rather difficult to tell why you are coming to a Dead Loop by just looking to a section of your code, however I can recommend you to take a look to the following attached application note which talks a bit about the Die-to-Die interface, and also I'd like to share with you an example code for this part that shows how to use the interrupts where the D2D is included.
