- Fri Jun 30, 2017 10:40 am #67772 I've been trying to flash one of the NodeMCU boards from Sparkfun for a couple of days and regardless of which firmware I try to upload, I get the same result:

Code: Select all ets Jan  8 2013,rst cause:2, boot mode:(3,7)

load 0x40100000, len 2592, room 16
tail 0
chksum 0xef
load 0x00000000, len 0, room 8
tail 0
chksum 0xef
load 0x00000000, len 0, room 0
tail 0
chksum 0xef
csum 0xef
csum err
ets_main.c


The part that indicates what's being loaded, from where, varies, depending on what image I'm uploading, but the end output is always the same (above, chksum is always 0xEF). I'm supplying a separate 3.3V to the FTDI and the module so I know it's getting enough power. I've gotten the same results using ESP Tool, Arduino (Windows and Mac). I've tried compiling and uploading (in Arduino's IDE) as a NodeMCU 1.0, 0.9, and a generic ESP8266 Module.

The board is SparkFun's ESP8266 WiFi Module. I'm interfacing with a Micro USB FTDI Basic Breakout Module

As an example, the last firmware I tried to upload was from Espressif (ESP8266_NONOS_SDK). As you can see below, it erased and uploaded fine (flashed by trying QIO and DIO SPI modes, with the same result).

In the screen shot, you can see the offsets I used. They are from Espressif's documentation. Someone please let me know if those are wrong.

I'm out of ideas and need an adult. Any insight would be really appreciated.

Output from last DL Tool re-flash:
