Many Core Dumps when wlan in ON! #434

Open ElinhoHD opened 4 years ago

ElinhoHD commented 4 years ago

The Pycom board is a W01 (Wipy version 1.20.1.r2 (Micropython 1.11 , ESP32 v 3.4.0)

(sysname='WiPy', nodename='WiPy', release='1.20.1.r2', version='v1.11-06dfad0 on 2019-11-30', machine='WiPy with ESP32', pybytes='1.3.0')

Hi, Since I use LittleFS on my project and let the wlan running, I have the problem that the component restart by itself leaving different messages like this (from ESP32):

Guru Meditation Error: Core  1 panic'ed (LoadProhibited). Exception was unhandled.

Dear @ElinhoHD,

with our Squirrel builds [1], errors like you've outlined might just go away.

With kind regards, Andreas.

Hi @ElinhoHD

Did you try to decrease the power transmission of WIFI?

I had a similar problem and it helped me: https://forum.pycom.io/topic/6389/w01-crashes-with-wifi-tx-at-max-power/2

However I would like to know why the W01 behaves like this.
