I have an Nvidia Jetson Nano that I was gifted by the Fedora project to
troubleshoot some arm specific packaging issues. That's done now so I
decided to see what else I could do with it.
I found NodeRED which had a module for the Raspberry Pi to control the
GPIO. I have since forked that project and have made some progress porting
it to the Nano.
Now I want to see if I can get the serial header working. From what I can
tell if running the linux OS provided by Nvidia there should be a serial
device named /dev/ttyTHS1 but it's not getting detected AFAICT grepping
I found the page for the serial-tegra that should be in the linux kernel
but if I try:
# modprobe serial-tegra
Nothing happens, no output if I try adding "-v" as an option either. So
does the module exist or not? If I try some random name in modprobe it
gives an error which makes me think it's present, but it doesn't load and
doesn't give me any helpful reason why.
