I reply here as it seems to be similar issue:

ESP-01 powered by external supply. It ran for 1 month. Now blue LED is on and via terminal serie I can see:

Fatal exception (0):
epc1=0x4021058c, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000
Fatal exception (0):
epc1=0x4021058c, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000
Fatal exception (0):

I tried reflashing at 0x000000 and later on 0x40000080. No luck.
After flashing blank.bin, I get no further messages, but ESP is useless.

What else can I try until I get new ESP I have bought? (they may take 2 months!!!)

Or any Diagnostic to conclude that ESP is dead?

Many thanks!

Sergio.

- Sat Oct 24, 2015 7:43 am #32187 I have the same situation too! The module has worked but at a certain point something went wrong. The blue led is always on and looking at the terminal I can understand that the problem is during user1.bin execution. It prints the fatal exception. I tryed to flash different firmwares but the only change is the memory position of the exception.
What is happening? Did anyone solved this problem? Is my module fried?

hi dmarkey.

No, same situation.
ESP is still in non-operative state, but without death certificate.
I have replaced by another ESP to reestablish service.

Hope I can recover or declare it as dead soon.
