unhandled double exception ESP32-S2 IDF 5.1.2 what is the cause?

Postby RalphD » Sun Dec 03, 2023 10:10 am

The following start up ends in extensa_vectors.S line 564 _DoubleExceptionVector:.

Previously the code was running fine until IDF 5.0.1, stopped loading in 5.0.4 and 5.1.2

what should I look at ?

Code: Select all
