Hi, I meet with this error with my Jetson Xavier NX (Jetpack 5.1.1). Do you have any suggestions? Thank you!

Hi, you can check where i2c is exposed in your system and then appropriately edit the following line:

https://github.com/opendr-eu/jetson_power/blob/main/p_est.py#L21

You are looking for iio:device0. Typically, these can be found in paths like /sys/bus/i2c/drivers/ina3221x/ or /sys/devices/3160000.i2c/i2c-0/.

You might also have to run the program as root. Please check https://forums.developer.nvidia.com/t/iio-device-symlink-missing/209612
