Hey Nordic Team,
I'm facing an issue while flashing the audio application on our custom PCB. The interfaces of the custom PCB pretty much match those of nRF5340 Audio DK. However, when I try to flash the audio application, it throws this error

Entering infinite loop
Now if I isolate the hw_codec part and move only that part to a separate project and flash that, it works perfectly fine.
PS: when i try to print the cs47l63_driver id once its passed to the initializing function, it shows 0x00 instead of the actual id.
