I’m trying to upload the copter firmware from my WSL ubuntu in Windows 10 to my pixracer. The build goes well until the upload stage when it hangs with the message below:
ubuntu@project$ ./waf --targets bin/arducopter --upload

If the board does not respond within 1-2 seconds, unplug and re-plug the USB connector.
Even if I unplug and replug the board nothing happens.
The upload works flawlessly on my other Linux laptop.
In my case the serial port should be /dev/ttyS10 as it is COM10 in Windows.
I’ve tried testing the serial port with cat /dev/ttyS10 but the prompt returns immediately with no output. When I try one of the other tty ports, I get
cat: /dev/ttyS5: Input/output error
My pixracer connects correctly to Mission Planner in Windows.
So it looks like this might be a port access issue in WSL? I’m not sure how to solve that. Has anybody gotten the same issue on WSL?
