I have an Afafruit NRF52 board with SD 132 and 5.1 dual fw bootloader. I implemented RTT logging and controlling (input) and the code is compiled using arduinoBuilder with RTT and debug level 3. The device uses to control DALI lights but sometimes it hangs, I can see that it does not responses to input and light level never changes.
I want to debug it, maybe getting a stacktrace to see where it hangs, hoping it's a software issue.
Any leads on how to do that ? Tutorial maybe ?
