I have a PIC device that interacts with my Jetson Nano using I2C and GPIO. We’re not sure what caused this, but we now only get timeouts on I2C bus 1. If I run
i2cdetect -y -r 1, it will take a long time for each address to return which will only give “–”. It seems to be something related to the hardware because I tested all other peripherals on another Jetson Nano and they work fine. I also switched the SD cards and got the same issue for that device.
I saw this post which says that it may have to do with regulator settings. I’m not sure what that is referring to. And we didn’t change any setting. It was running in 10W mode. The problem also still occurred when I disconnected most other peripherals.
