Hi,

I just got my Xavier NX, but I cannot enable cpu cores with sudo jetson_clocks

sudo jetson_clocks --show
SOC family:tegra194  Machine:NVIDIA Jetson Xavier NX Developer Kit

Here are the outputs of some commands:

It is managed by nvpmodel. You may use nvpmodel before jestson_clocks:

sudo nvpmodel -m0
sudo jetson_clocks

Thanks,
figured it out just before your reply!
