Hello,

When we unplugged the ssd from drive, it lock all the USB ports.

There is a small chance to bring the USB back when we reload the USB driver, otherwise we need to restart the system.

how to enable 8 cores, nvpmodel -m 0 not working, current can only use 6 cores.

Dear dhruvildarji1409,

-. USB
Does the symptom happen all USB port or a specific USB port?

-. CPU cores, please refer to below link and comments.

https://devtalk.nvidia.com/default/topic/1055220/general/tegrastats-reports-only-6-cpu-cores-/

This is expected; the Hypervisor setup for 5.0.13.2/DRIVE Software 8.0 was 8.0 shared cores across all the VMs, where 5.1.0.2/DRIVE Software 9.0 and later have 6 dedicated cores for the guest OS, and the remaining two shared for the non-guest VMs. This is to give more predictable performance to the guest VM by eliminating any interference from the Foundation Service VMs.

This doesn’t seem to be well documented anywhere unfortunately; best picture from the docs to explain against is below.

The tool is for Jetson platform not Automotive platform. Thanks.

Dear dhruvildarji1409,

Could you help to check on hostPC if DriveAGX USB ports are available or not using lsusb command like below? Thanks.

Dear dhruvildarji1409,

Thank you for you update.

One more thing, could you please help check below step and upload log info on this topic? Thanks.

  1. Run “sudo minicom -D /dev/ttyUSB2” on HostPC for XavierA
  2. Plug in a USB device to DriveAGX USB port
  3. Check log HostPC minicom terminal
  4. Unplug a USB device from DriveAGX
  5. Check log HostPC minicom terminal

Hi dhruvildarji1409,

Could you follow our last comments to provide the log if this USB problem still an issue to support?

Thanks
