Nvmodel fails in javier nx devkit

I am running nvpmodel in javier NX SOM production emmc SOM with devkit.
But the nvpmodel is not properly set.

NVPM WARN: write PARAM CPU_DENVER_0: ARG MAX_FREQ: PATH: /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq VAL: 0
- probably failed due to it is less than current min value 1190400
NVPM ERROR: Error writing 0 to /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq: 22
NVPM ERROR: failed to write PARAM CPU_DENVER_0: ARG MAX_FREQ: PATH: /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq VAL: 0
NVPM ERROR: failed to set power mode!
NVPM ERROR: optMask is 1, no request for power mode

Also when I run two camera stream in xavier nx devkit , I get reduced fps (0-2fps).The actual fps set on sensor is 60. I get the below mentioned error while streaming in gstreamer.

WARNING: from element /GstPipeline:pipeline0/GstFPSDisplaySink:fpsdisplaysink0/GstXvImageSink:xvimagesink0: A lot of buffers are being dropped.
Additional debug info:

There may be a timestamping problem, or this computer is too slow.

Can anyone help me fix this issue ? Thanks in advance.

hello vikaash.kb,

may I know which JetPack release you’re working and which sensor module it is?

Hi @JerryChang ,
We use L4T 32.4.3 and it is imx327 sensor module . The same command(on same L4T package) works on my custom board which is based on NX and three imx327 cameras and one ar1335 camera. But the nvpmodel doesn’t work in xavier nx devkit.

hello vikaash.kb,

are you using the customize power modes?

there’re default NVPModel clock configuration for Jetson Xavier NX.
please refer to developer guide, Supported Modes and Power Efficiency.
BTW, the nvpmodel GUI is represented by an NVIDIA icon on the right side the Ubuntu desktop’s top bar to change power modes.

Denver is unexpected with Xavier, it is only applicable to TX2.
Not sure, but maybe you’ve flashed the wrong rootfs or did not correctly configure your Jetson flash.
