That jetson_io tool shows i2c on pins 3 and 5 (where I have it connected) and is labeled as “i2c8” (which I would guess means bus 8). It doesn’t allow for any reconfiguring of the i2c device tree (overlay), from what I can tell. I looked at the actual device tree file and it doesn’t look like it’s properly configured for i2c on those pins (mind-you I’m no device tree expert). I am hoping to avoid going down the path of doing my own device tree (or device tree overlay). I was hoping Seeed would have something for this already (maybe they do and I just haven’t found it yet).
