Hi everybody,
I built firmware for my nodemcu board from https://nodemcu-build.com/ build.com/ and I writed it via esptool. It was succesful. Now I am trying connect to my nodemcu board, but I can't. I am using nodemcu-tool and luatool. When I type nodemcu-tool devices, I am seeing my board. But when I want upload something, I get no response from nodemcu.
Anybody know how to fix it?
Thanks a lot for help

What board are you using?

On a devboard v2.0 ( with esp12e module ) I flashed the firmware with pyflasher ( https://github.com/marcelstoer/nodemcu-pyflasher ):
- selected Flash mode->Dual Flash I/O (dio)
- slected Erase flash->yes, wipes all data ( only the first time )
