Some issues observed in using Jetson Xavier NX

Hello nVidia Support,

I am using Jetson Xavier NX module, and I used the “SD card image method” in creating the microSD disk for the module.

During the usage in about 1 month, it is observed below issues:
1). sometimes the L4T system could for unknown reasons reboot.
2). cat /proc/cpuinfo only shows two ARM processor. should it show as 8 cores?
3). how can I make use of all the 8 ARM cores?

I would like to check could the unreliability issues be caused by the way microSD card image being created? should I install the SDK Manager manually?

Thank you.

Hi,

1). sometimes the L4T system could for unknown reasons reboot.

This needs further debug. Please try to dump the serial console log and wait for this error happens and see if any error is printed before reboot.

2). cat /proc/cpuinfo only shows two ARM processor. should it show as 8 cores?
3). how can I make use of all the 8 ARM cores?

We have some power mode supported on NX. Not every mode uses all CPUs.

Plese refer to

You could use tool “nvpmodel” to switch between different modes.
