ESP8266 Community Forum

Dear experts,

I am using esp8266 v12-f and boot-loader 1.7.
I got erasing failure at sector 1 (0x1000) while I was trying upgrading firmware over OTA.
The MCU hang then reset (because of WDT resetting timeout).
This is never happened when I do upgrading firmware onto USER 2 space.
Please help me how to fix that. We are going to finalize our prototype phase but we have to pend it because of this issue.
Thank you and regards,
Fitz

You're with the same problem as me. Nodemcu does not restart after the sketch download
