Hello, Developers.

When I upload the px4firmware or Ardupilot via usb, bootloader says like below.

What are the meaning of “type, idtype, vid, pid, coa, sn”?
And Can I change this values??
If Can, how can I change this values??

Thanks for reading.

Those are USB related things, not necessarily flight controller things. Why do you want to change them? What to?

Thanks for rely.

I just want to know for px4 bootloader study :slight_smile:.
