Please see my post 'NOT SOLVED ESP-07 endless loop-jmp user1, Fatal excption(0)'
Your problem seems to be like mine.

Was your ESP working before ?
My was. First with AT command, then with Lua. Then it stopped (after uploading new code with ESPlorer).

I will try to flash it with blank512k.bin.

- Thu Apr 09, 2015 5:35 pm #14039 My ESP-07 worked with the stock sent 'ai-thinker.com' firmware.
Then I updated it with nodemcu but after I had same problem as your.
I can flash number of times but it doesn't start and go in an infinite loop. Both leds are lit.

I already empty flash with 'blank512k.bin' but no result...

Please can you post your bootloader output COM@76800bps ?

Sory I did not check replays here for a few days. I will send you my bootloader later today.

BTW: Did you tried with latest AT firmware ?
