Hi Jerry, thanks for your anybaud post - that got me seeing the bootloader output for the first time.

Unfortunately it looks like this:

ets Jan  8 2013,rst cause:1, boot mode:(3,7)

    ets_main.c 

So I think my ESP-01 is truly dead, unless I can get in at a deeper level.

Hi Julian, While I don't have a good understanding of the boot loader messages yet, it looks to me like you simply need to reflash your ESP-01. Try something simple like a 'Hello, World' program, maybe like the one in https://github.com/jdunmire/esp8266_appTemplate or something that comes with the SDK. I use this one: https://github.com/pfalcon/esp-open-sdk

There is also lots of friendly help available at ESP-8266 forum: http://www.esp8266.com/

Hi Jerry - I got it fixed.  One time out of 10 it booted into flashable mode. Probably my wiring. Still lots of bugs in my code, but getting there. https://github.com/jcable/nmea-link Julian

Hi - did you get past the System Param Error? I'm flashing an ESP-06 module and get a similar error. I've tried with an esp_init_data file and without, and ive tried numerous different images from http://nodemcu-build.com/

after hacking on this all day, the problem I had was the ESP-06 is actually 1MB(8mbit) of flash, not the usual 512k of flash in the ESP-01,03 etc. So once I flashed the firmware with --flash_size 8m NodeMCU booted up!
