- Fri Aug 12, 2016 5:12 am #52773 ChrisSparks - that's the exact sequence of events I get..

I'm going to have a go at trying the various methods that have been suggested on here and also compiling from scratch.

I'll let you know how I get on and if I'm successful I'll post the steps on here (including the working bin files!)..

This is missing the flash parameters for a 4 MByte module. Something like:

Code: Select allsudo python esptool.py --port /dev/ttyUSB0 write_flash -fs 32m -fm dio 0x0000 nodemcu-master-22-modules-2016-08-10-16-54-08-float.bin 0x3fc000 esp_init_data_default.bin

Depending on the type of module '-fm qio' could also work.

This is what I got:
esptool.py v1.2-dev
Connecting...
Running Cesanta flasher stub...
Flash params set to 0x0240
Writing 495616 @ 0x0... 495616 (100 %)
Wrote 495616 bytes at 0x0 in 43.0 seconds (92.3 kbit/s)...
Writing 4096 @ 0x3fc000... 4096 (100 %)
Wrote 4096 bytes at 0x3fc000 in 0.4 seconds (83.8 kbit/s)...
Leaving...

I was able to connect at 115200 well yeah!

I was able to run my first init.lua script (the one that setups up a connection to my router) and it was happy!

Thanks for the help.

You're very welcome. Glad to see that everything works well now for you

Success - thanks devsaurus..
The first bin I tried to flash (18 modules) didn't work, I tired it with both dio and qio so I moved on to one with less modules (14).
This flashed straight away and instantly booted into nodemcu lua environment..


Thanks for the help.
