@CAProjects and @duwudi: thanks, the strange thing I noticed is that when the universal pcb is connected gps no longer works.
With a fresh build and the universal pcb not connected the gps works. Once I connect the universal pcb I get the following output when running cat /dev/ttyS0.
And bind issues
My gps unit is connected to the pitop gpios.
The usb on the universal pcb is connected to a wifi card and works without issues.
It’s just this behaviour of the gps connected to the gpios that is confusing me to think this additional usb on the universal pcb is using serial.
Any suggestions or help is more than welcome as I would very much want to use the Gps on the gpio and make use of the additional usb port on the universal PCB
