NVIDIA found a software issue when using in the JetPack 5.0.2 (r35.1) release with Jetson AGX Orin 32GB commercial module. The issue may cause only four CPU cores out of total 8 CPU cores to be available on Jetson AGX Orin 32GB commercial modules. NVIDIA has a patch to fix the issue and can be found in[Jetson Linux 35.1 page](https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdeveloper.nvidia.com%2Fembedded%2Fjetson-linux-r351&data=05%7C01%7Csuhash%40nvidia.com%7C8267a3d36f5347e74adb08daf95108c5%7C43083d15727340c1b7db39efd9ccc17a%7C0%7C0%7C638096423740659016%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=k12wbKXiZiv9FkcAR0hpBNtvybfM3rArFF%2Fc18CjV0c%3D&reserved=0).

Hi, I replaced the “uefi\_Jetson\_RELEASE.bin” from "Orin-cpu-and-thermal-fix’"into the "Linux\_for\_Tegra/bootloader’“directory, and after re-flashing the AGX ORIN 32G, the number of CPUs is still showing as 4 when using the `lscpu` command.” [flash.log](https://forums.developer.nvidia.com/uploads/short-url/dmaihhxZIdoi5Ut7BRpnQCRa718.log) (79.8 KB) [flash&reboot\_debug.log](https://forums.developer.nvidia.com/uploads/short-url/qNYhR5nd9pwIimhOq6BCDKM3fUP.log) (111.5 KB)
