ESP8266 Community Forum

- Wed Jul 26, 2017 7:02 pm #68606 I'm an AVR convert, and I have ported existing Mega 2560 code to ESP8266. After getting it to run it was pretty stable I thought. Then I noticed uptime was not moving forward. I have the visible kinks worked out but this one eludes me. So I started logging stack dumps to EEPROM and on the next reboot offloading it into SPIFFS.

Here's what I'm getting:

Code: Select allCrash information recovered from EEPROM

I put it into the decoder, but I'm a little lost from here. Do I read it top as newest event or bottom? How am I supposed to use this to dig my code?

I could use some ESP wizard help. Thanks.
