is NodeMCU online and the Lua interpreter ready ?

[ellenfel]

I am running this tool on ubuntu16.04
and iam currently following instructions from:
https://github.com/nodemcu/nodemcu-firmware/blob/release/docs/getting-started.md#nodemcu-tool

after installing NodeMCU-Tool globally with $ npm install nodemcu-tool -g
running $ nodemcu-tool --version gives 3.2.1 so i assume installation was successful but when i try to upload a lua file
$ nodemcu-tool upload --port=/dev/ttyUSB0 helloworld.l,

[NodeMCU-Tool]~ Unable to establish connection
[NodeMCU-Tool]~ Timeout, no response detected - is NodeMCU online and the Lua interpreter ready ?
error messages returns.

$ nodemcu-tool devices returns
(node:18906) Warning: Accessing non-existent property 'padLevels' of module exports inside circular dependency
(Use node --trace-warnings ... to show where the warning was created)
[device] ~ Device filter is active - only known NodeMCU devices (USB vendor-id) will be listed.
[device] ~ Connected Devices | Total: 1
[device] ~ - /dev/ttyUSB0 (1a86, usb-1a86_USB2.0-Ser_-if00-port0)

This issue has opend here before in : #25
and the solution was: $ nodemcu-tool mkfs --connection-delay 1000
but unfortunattly this just returns the same error that returns when i try to upload a lua file.
