ESP32 Possible crash with default header feature

timstans commented 6 years ago

when sending a http request the esp32 crashes with the error below

Guru Meditation Error of type InstrFetchProhibited occurred on core 1. Exception was unhandled. Register dump: PC : 0x00000000 PS : 0x00060630 A0 : 0x800d63b2 A1 : 0x3ffe21a0

anybody know how to fix?

So you basically gave us no info at all... where is your code? how are you setting things up? Why not decode that exception (https://github.com/me-no-dev/EspExceptionDecoder)? Please give more info or there is really nothing that anyone can do.
