Hello,
On the imx8mpevk, I2C busses 3 and 5 are the ones exposed on the expansion connectors. But they don't seem to be enabled in core-image-base. Running i2cdetect on those busses gives
Error: Could not open file `/dev/i2c-5' or `/dev/i2c/5' : No such file or directory
Are any extra steps required to enable them? Other I2C busses are working but as far as I can tell they are not accessible on the expansion connectors.
Thanks
Solved! Go to Solution.
It seems like the main expansion connector, labelled as I2C3 in the schematic, is actually I2C2 in the image. So problem solved. Just an off-by-one thing I guess.
