Wifi not working
Posted: Mon Dec 19, 2016 7:17 pm
Hi all,
I tested my ESP32 with basic WiFi samples and everything was allright. I then moved on and started playing with NVS to store some info which was working great too. Problem is I think I managed to break/corrupt something on the ESP32. When I flash another of those WiFi basic samples, e.g. this one:
Flash works ok but ESP32 keeps continuosly rebooting. I made menuconfig and turned on any verbosity setting I could see and this is what I am getting:
After that no more logs, just ESP32 rebooting all the time.
Any ideas? I am lost at the moment.

. It was the damn USB cable. I just changed to another one I had around and it is working like a charm. Thanks for pointing me on the right direction I was going mad! To be honest never thought of that, I though my board (official Dev Kit from Espressif) was just mental.
