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 inJetson Linux 35.1 page. Please refer to the table at the end of the Jetson Linux 35.1 page. The fix will be included in the upcoming JetPack 5.1 release.
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.”
