Settings in Arduino IDE

Board NodeMCULuA 1.0
CPU 80 Mhz
Upload Speed 115200
Flash Size 4M(1m SPIFFS)
Programmer AVR ISP

Provided access to the ttyUSB0 by command sudo chmod 666 /dev/ttyUSB0

Previously worked on 16.04.
What can be the problem and how to solve it?
Behavior chip also changed. Earler diode only flashed when sketch was uploading, now is always on till the sketch start uploading and switched off when error is displayed.

Any help will be usefull.

Please check that you are member of dialout group.

If not please add yourself to this group by running sudo usermod -a -G dialout $USER, log-out and log-in again.

For more predictable results you may try to run esptool.py directly to check that your board is alive:

sudo apt-get install python3-pip
sudo pip3 install esptool

esptool.py --port /dev/ttyUSB0 chip_id

You will get output which is similar to shown below:

If it does not help - check your wiring, board temperature, cable and so on.

Here is what I did...

1. Install Arduino using scripts from the Arduino Website (preferably run the install.sh as sudo)


2. 
   

   Run the arduino from terminal as sudo:

   
   
   

   sudo arduino

   
   

Everything worked after this...

Note:

'sudo arduino' and 'arduino' launch different environments of IDE so make sure you don't waste time setting up one without sudo.
