Problem uploading binary to nano328P

Development Platforms
1

I’m having problems uploading my binary. Uploading works on the Arduino IDE I have installed on my laptop running Ubuntu 20.04. I have tried changing the upload speed to 57600, as has been suggested on a previous post, but this hasn’t worked. It seems to be auto-detecting the wrong port for some reason.

When I scan the available ports the following is returned. I select the 4th option
— Available ports:
— 1: /dev/ttyACM0 ‘DW5560 - Dell Wireless 5560 HSPA+ Mobile Broadband Mini-Card Modem’
— 2: /dev/ttyACM1 ‘DW5560 - Dell Wireless 5560 HSPA+ Mobile Broadband Mini-Card Data Modem’
— 3: /dev/ttyACM2 ‘DW5560 - Dell Wireless 5560 HSPA+ Mobile Broadband Mini-Card GPS Port’
— 4: /dev/ttyUSB0 ‘USB2.0-Serial’

Here is the error

avrdude done.  Thank you.

The terminal process "platformio 'run', '--target', 'upload'" terminated with exit code: 1.

My platform.ini file

So it’s detected the wrong upload port for you if you say /dev/ttyUSB0 is right.

See docs and docs.

That is correct. The port Platformio uses does not correspond with USB port scan, which is indicating /dev/ttyUSB0 ‘USB2.0-Serial’ and which I have selected by entering 4 on the command line

If you have multiple serial devices attached to your computer (which seems to be the case if you have /dev/ttyACM0 then try to add

upload_port = /dev/ttyUSB0 
monitor_port = /dev/ttyUSB0

to the platformio.ini to override the auto-selection, per above.
