Getting error while uploading sketch ESP8266

[embhobbb]

Hi,
i have install esp8266 package and i could able to compile the code.
but not able to upload the code to esp8266.
Here is error i got while uploading code..

./arduino-cli-0.2.2-alpha.preview-linuxarm upload -p /dev/ttyUSB0 --fqbn esp8266:esp8266:nodemcu Arduino/blinking/
No new serial port detected.
warning: serialport_set_baudrate: baud rate 0 may not work
warning: espcomm_sync failed

Error during upload.

I think it has maybe caused by some reasons such as: bad usb cable connection, the serial port is busy (/dev/ttyUSB0 is using by another session). I'm having a problem while uploading too. My question is: Though I built sketch sucessfully, can I upload to device which can not be detected?

    }
  ],

USB is detected properly. I am facing problem while setting Baud rate. How to set the baud rate and how to upload the code to esp8266?
@zunoffon please create another thread if you are facing some other problem than what i mentioned?

This is a bug in 0.3.0-alpha, I've fixied it and releasing an update shortly...

[embhobbb]

i have downloaded the 0.3.1 version. But i am still getting same error.
Do i need to update anything other than CLI executable?

$ ./arduino-cli-0.3.1-alpha.preview-linuxarm core install esp8266:esp8266

Compiled sketch not found. Please compile first.

i tried many combination but still not working.

Please guide me to use correct switches.

[cmaglie]

Please remove the @2.4.2 piece is not part of the FQBN, try with:

esp8266:esp8266:nodemcu.menu.UploadSpeed=115200

[cmaglie]

sorry I mean:
esp8266:esp8266:nodemcu:UploadSpeed=115200

[cmaglie]

BTW this is another issue, if the problem persists please open a new issue with a transcript of your latest try.
