Support for Nano and Xavier NX #83

Closed caruofc closed 1 year ago

caruofc commented 1 year ago

I am having issues with Jetson Nano and Xavier NX. I am using Jetpack 4.6 for both. In Nano, there is no "/proc/device-tree/chosen/plugin-manager/ids" or "/proc/device-tree/chosen/ids" in my system and therefore find_pmgr_board() call in GPIOPinData.cpp fails. And for Xavier NX, none of the matches() call in get_model() returns true and therefore it says "Could not determine Jetson model". So, my question is I guess, does this code support Jetson Nano and Xavier NX? What are the models that it specifically supports? Is there a list of supported models? Thanks.

This library does support Nano and Xavier NX. I've only directly tested it on Nano because that's the only one I have, but it should work on Xavier NX because this library is basically just a C++ translation of Nvidia's official python library.

In Nano, there is no "/proc/device-tree/chosen/plugin-manager/ids" or "/proc/device-tree/chosen/ids"

That's weird. Are you using customized image or something? I'm using the official Jetson Nano developer kit image and it works.

Hmm... OK, here's my suggestion. Go to the official python library's repository and try the library on your devices. If those paths don't exist, the official python one should not work neither.

If it doesn't work on your devices, I think it's the best idea to ask them how to fix the issue. Like I said, this library is a C++ translation so it should work same as the original one. If the official python library works on your devices, then we must did something wrong.

No response. Closing it.
