2 cores at 0%

Hi,
The issue is present if you install SDK components(including CUDA, TensorRT, …) through SDKManager or do OTA update. If you don’t need the packages, the step is not required. Please check

Cannot enable denver cores for TX2 (Jetpack 4.4 DP)

Currently, you could set “isolcpus=” in kernel command line to enable all the cores. However, OTA update does not preserve this setting so you may need to manually set this again after you try the OTA (apt update/upgrade).
