ESP32-PICO-V3-02 PSRAM test crash
Posted: Thu Oct 05, 2023 2:51 pm
Hi!
We have run into a problem with our custom ESP32-PICO-V3-02 based hw crashing on PSRAM test:
This only crashes on about 10 devices out of 1000. The rest work fine. Also making modifications to the app code prevents ESP32 PSRAM test from crashing. If disable PSRAM test in sdkconfig then it won't crash either.
Any advice where to look into?
Thanks!
