Unique hardware identifier

Autonomous Vehicles DRIVE PX 2 DRIVE Hardware
1

Is there a way to programatically get any unique hardware identifiers, like serial numbers, on the Drive platforms?

We are looking for a way to identify single instances to implement licensing.

Dear katwa,

You can get the HW info with those command.

cat /proc/device-tree/chosen/nvidia,sku
cat /proc/device-tree/chosen/nvidia,sku_version

On our Drive PX, this file is empty. So, no hardware info there.

ls -la /proc/device-tree/chosen           

total 0

drwxr-xr-x   2 root root   0 Dec  2 09:44 reset

Any other suggestions?

Dear katwa,

Could you please let me know if you have DrivePX2 or DrivePX?

If you have DrivePX2, you can see below info.

If you have DrivePX, unfortunately DrivePX is an old model and no longer supported.

Yes, we have a Drive PX. Thus no such file.
Thanks for your help.
