ESP8285 cannot run into user.bin sometimes

Postby Nicholas3388 » Thu Nov 15, 2018 6:13 pm

Hi, My ESP8285 sometimes cannot run into user2.bin when the firmware is upgraded via FOTA. The logs are as follow:

As you can see from the logs, the system is about to jump to user2, and then crash immediately and stop running. When I reboot the device by pressing the reset button manually, it will run without problem. This issue happen sometimes. Is there anyone know how to handle this issue?

The same user2.bin, sometimes it runs successfully, sometimes it fails? Maybe the log of success running can tell something.

Are you running Firmware over the air?
