Solid blue light after flashing eagle.flash.bin, help!

Postby pcm2a » Wed Sep 28, 2016 10:42 pm

I have an ESP8266-01, the 8mbit module. Before any flashing it had version 1.3 of the firmware on it and AT commands worked great. After this I flashed a wifi example Sketch to it and this worked fine as well. Now I want to flash the eagle.flash.bin back on to revert to the non-os stock firmware.

1. I am using the latest ESP flasher version 3.4.2
2. I have tried the latest 2.0 sdk and also an older SDK 1.5.4
3. The flash tool reads my ESP correctly and automatically sets the 8mb option
4. I flash:
eagle.flash.bin 0x0
esp_init_data_default.bin 0xFC000
blank.bin 0xFE000
eagle.irom0text.bin 0x40000
5. The flash takes 15-20 seconds and completes without errors
6. I restart the module and the light is solid blue
7. I connect to the module and it is sending out constant garbage

I have read many guides and I am not sure what I am missing to successfully flash back to a non-os no-OTA firmware so I can execute AT commands again.

Hello,

eagle.flash.bin 0x00000
eagle.irom0text.bin 0x10000
blank.bin: 0x7e000 & 0xfe000
esp_init_data_default.bin: 0xfc000

You could try this! Find the BIN files attached and let me know if this worked for you...
