what will cause reboot issue

Postby alvin_xie » Thu Jun 28, 2018 8:56 am

I power off the ESP32 for 5 sec. and then power on it.
But the ESP32 will always reboot.

here is the log:

Maybe this?

Code: Select all

csum err:0xe6!=0xc8

0x33 means you have gpio12 pulled up and should have 1.8v flash (wrover or d2wd), do you?

As above, disconnect pin 12 and try again. I avoid pin 12 if I can.

Alternatively, use espefuse.py to set flash voltage to 3.3V. Then the state of GPIO12 will not matter.
