Thanks @Amycao for quick reply. Can u explain what’s the use of BSP packages in jetson devices? because in local machines it’s very straight forward .

It includes kernel, bootloader, drivers, flashing utility, sample filesystem, and more for the Jetson platform.

Thanks @Amycao for this info .

Steps to resolve this tracker issue:

  1. first check whether your jetpack and tensorrt installed properly or not .
  2. Fix those issues
  3. Then try to install DS-6.0 from scratch .

Thanks
