Tool/software:
I have identified that the ISR for IPC communication is not executing while adding code for IPC data communication in the EtherCAT CM file.
The main routine of the EtherCAT CM is as follows, and the IPC register configuration is depicted in the adjacent image.





The interrupt function is implemented as follows.


As seen in the code, I've placed tests within the interrupt function, but they all return 0, indicating that the ISR isn't executing. I've already validated the IPC functionality using example files before integrating it into the codebase. I'm struggling to identify where things might have gone wrong.
