Can you help debug an ESP32 demo crash?
I’ve had this set of demos from Sublime for a while now:
https://github.com/marcmerlin/SmartMatrix_GFX/tree/master/examples/zNO_GFX/Sublime_Demos
The problem is that they work perfectly fine on ESP8266, or Teensy, but one of them crashes (reboot) with no traceback last time I spent a while doing printf debugging, it felt that I was just moving the crash around as code alignment/compilation was changed.
I’m almost certain it’s an ESP32 core bug, but I can’t prove it and can’t narrow it down, because when I do, it just moves/goes away.
+Yves BAZIN or someone else with ESP32, is that something you’d have the time, skill and curiosity to debug on your ESP32 rig?
https://github.com/marcmerlin/SmartMatrix_GFX/blob/master/examples/zNO_GFX/Sublime_Demos/Sublime_Demos.ino#L215 you’d think it’s an obvious out of bounds write, but
1) I haven’t found it
2) typically ESP32 will catch those and give a traceback, which it does not there
You’d have to take the code, install FastLED::NeoMatrix and change config.h to comment out SmartMatrix
https://github.com/marcmerlin/SmartMatrix_GFX/blob/master/examples/config.h#L4
and define the init of your array (pin numbers and resolution), it’s reasonably easy to do.
