GPIO0/GPIO2/CH_PD/RES pulled-up, GPIO15 pull-down ...

I had a very similar issue. Uploading a sketch always turned the module into a state posting following message to the serial console:

ets Jan 8 2013,rst cause:2, boot mode:(3,6)

load 0x4010f000, len 1384, room 16
tail 8
chksum 0x2d
csum 0x2d
v60000318
~ld


I was able to track this down to another cause as posted here before (I tried this too but did not resolve the problem facing with my module).

The cause I found is that the board and programmer was configured incorrectly in the Arduino IDE (v1.6.8 with ESP add on from github installed via the Boards Manager).
I bought a NodeMCU ESP-12E board and also selected "NodeMCU 1.0 (ESP-12E)" as board in the Arduino IDE. This actually is WRONG. I have no clue what the Arduino IDE does, I assume it tries to upload a lua sketch in this mode or something else but it definitely does not work for generic Arduino sketches.

After setting the board to "ESPino (ESP-12 Module)" and the programmer to "Arduino as ISP" the upload worked fine and the module starts the sketch as expected.

Hope this is helpful for other people stumbling across this thread.
