ESP32 RAM cache issue when using both cores
Just wondering if this bug: https://www.neonious-basics.com/index.php/2019/01/27/esp32-wrover-is-fundamentally-broken/ may affect some of the Pycom modules and explain some of the crashes that have been reported here or there?
From what I understand, the issue is related to the use of the top 2 MB of the external 4 MB PSRAM when using both cores. Not sure if this is specific to the ESP32 itself or the WROVER module specifically, though.
