Got an answer, I was running Ubuntu-rockchip 22.04 on the opi5b, so it's a different setup outlined here:https://github.com/Joshua-Riek/ubuntu-rockchip/issues/229

I'm trying to enable i2c3 on my orange pi 5b, according to the user manual, i2c is disabled on the 26 header pins by default, and to enable them, you need to edit the /boot/orangepiEnv.txt file, however, my orange pi doesn't have that file. I tried creating a new file and copying the required instructions, then restarted linux, but it still didn't work. Has anyone encountered a similar issue or does anyone know how to resolve this?
