- Mon Mar 21, 2016 6:47 am #43698 Has anyone had success on the ESP8266 Thing board <https://www.sparkfun.com/products/13231>?

I keep getting these errors:
"Failed Wifi Connect"
"file open failed"

I flashed ESP Basic 1.89, using esptool.py and the FTDI Basic 3.3.

The error msgs about the files missing is normally fine and will go away after you have gone to the settings page and saved some settings to the device.

Other that that it should be smooth sailing.

I flashed the 512K version, and it seems to be fully functional.

Setup
-----
- ESP8266 Thing (not the Thing Dev board)
- FTDI Basic 3.3V

Procedure
---------
- Power up the Thing.
- Plug in the FTDI Basic.
- Find the FTDI device designation:
> ls /dev/tty.u*
- Use esptool.py to flash the 512K-bit format file.
> esptool.py -p /dev/tty.usbserial-AH03F3Q3 write_flash 0x00000 512k.bin
- Use esptool.py to flash the 512K-bit firmware file.
> esptool.py -p /dev/tty.usbserial-AH03F3Q3 write_flash 0x00000 ESP8266Basic.cpp.bin
- Unplug the FTDI Basic and power cycle the Thing.
