Info:

1. Core2-for-AWS-IoT-EduKit/Factory-Firmware: commit 40e9c3a
2. esp-idf: commit c40f2590bf759ff60ef122afa79b4ec04e7633d2 (HEAD, tag: v4.2)

And we are not using "platformio", and use idf.py the bulid and flash image to m5stack.

Thank you.

That's fascinating. We're actually updating the BSP from the bottom up currently and we'll refactor all of the firmware after that's done. I am hope that it will fix that issue as a by-product of the latest round of updates since we find a few ways to optimize the display task using libraries provided by the community.

Which sensor screen is it on when it crashes? Home/any? Or one of them specifically?
