L4T 32.7.1
I set the CPU and GPU frequencies to the lowest limit and measured the CPU and GPU voltages with ina3221 but it didn’t change. The command is:
cat / sys / bus / i2c / drivers / ina3221x / 7-0040 / iio: device0 / in_voltage1_input
The document say that the CPU power management strategy uses dynamic frequency scaling with dynamic voltage scaling.
I would like to know how to change the voltage of the CPU.

Please execute sudo tegrastats to get the status of CPU/GPU engines. It veries automatically per system loading and we cannot manually control it.
