I’m about to go absolutely insane with this problem. I just can not get platformio to accept any port.
I’m running Fedora 34.
Here is my config
[env:ATmega1284P] platform = atmelavr board = ATmega1284P framework = arduino upload_port = usb upload_protocol = atmelice_isp upload_flags = -e
When I run avrdude through terminal it will happily accept usb or nothing at all as an upload port, when running set fuses it will also find my board without any trouble. But putting usb (as in my config) it will spit out
No such file or directory: ‘usb’
through pio device list I can see my programmer is connected to /dev/ttyS0 but using that will give me
avrdude: jtag3_open_common(): JTAGICE3/EDBG port names must start with "usb"
Using /dev/ttyS0 in terminal will give the same error. I’ve been trying to get platformio to ignore the upload_port and send it through to avrdude anyways since it seems it can handle it but very unsuccessfully.
avrdude command I used to check connection
avrdude -p ATmega1284P -c atmelice_isp
Any guidance is very appreciated.
