DevKit can be flashed with old firmware but not new firmware
Posted: Tue Sep 13, 2016 2:17 amI used the custom builder to create a nodemcu binary (nodemcu-master-7-modules-2016-09-01-04-30-49-float.bin) keeping all of the default modules and adding none. Using esptool.py, flash_write completes without error. I'm using an ESP12E DevKit. I've tried a variety of --flash_mode and --flash_size, but when I restart the DevKit I get gibberish at 9600 and 115200.

However I can flash an earlier binary: nodemcu_float_0.9.6-dev_20150704.bin which I found floating around on the web somewhere, and it works just fine. Here is the successful command...
I can also flash v1111ATFirmware.bin successfully using...
esptool.py --port /dev/ttyUSB2 write_flash --flash_mode dio --flash_size 32m 0x0 v1111ATFirmware.bin
Any ideas on what I do next to figure out how to flash the newer nodemcu binary correctly? The older one doesn't have tmr.create(), which I'm going to need. Thanks.
