I’ve lost a couple of nights worth of sleep trying to get something simple to work. I have a esp32-s3-devkitc-1 that I’m trying to do a basic hello world debug on the IDF framework. If I do the same with the Arduino framework everything debugs fine so it is definitely a software bug and not hardware related.

I’m able to read global variables but no local variables or hit a break point at printf or taskDelay for example.
Any help will be appreciated.
