Heap Corruption Guru Meditation Error: Core 1 panic'ed (StoreProhibited)
Posted: Fri Dec 11, 2020 10:47 am
Hello,
My ESP sketch scans for Bluetooth devices and shares data across Mesh. Recently I wanted to add an OLED display but this has resulted in Heap corruption. For Mesh I am using https://www.arduino.cc/reference/en/lib ... less-mesh/ Painless Mesh library, for OLED I am using https://github.com/ThingPulse/esp8266-oled-ssd1306 esp8266-oled-ssd1306 library.
I am getting the following error on Serail port and the ESP32 keeps on restarting. I am using ESP-AI Thinker board.
After decoding the error
As you can see the error occurs at line 172 where I am trying to write to a pointer location. Strangely commenting the OLED setup function makes the error goes away. Has anyone else come across similar problem?
