Jetson Nano and I2C

Hi,

I’m trying to make use of smbus for i2c. I’m getting compile errors if I include #include <i2c/smbus.h>. Does the Nano not support smbus? I’ve also found smbus.h at </usr/src/linux-headers-4.9.201-tegra-ubuntu18.04_aarch64/kernel-4.9/include/config/i2c/smbus.h>, however, the file is empty. So this conclude me to believe, the nano does not support it. Is it located else where? Or could I get a confirmation that it is not supported.

Thanks,
Jonathan

Yes looks like not support smbus.
