gc.collect() may cause panic

Post by bertel » Fri Mar 05, 2021 5:52 am

With recent uploads of GENERIC esp32 firmware., gc.collect() can cause panic and lead to a hard reboot. I have observed this with all esp32 GENERIC firmwares since and including esp32-20210222-unstable-v1.14-80-g75db0b907.bin, using a standard esp32-WROOM. An issue has been raised https://github.com/micropython/micropy ... sues/6988
