I use a Manifolod2-G, and want to get power measurement from it, I read the report about Jetson TX2. I execute the above command as:
cat /sys/devices/3160000.i2c/i2c-0/0-0040/iio_device/rail_name_*
the Manifolod2-G result "No such file or directory".  I don't find the directory named iio_device.
How to do it? Thanks a lot.
