NOTES:
With JetPack 7 series, Jetson software aligns with the Server Base System Architecture (SBSA), positioning Jetson Thor alongside industry-standard ARM server design. SBSA standardizes critical hardware and firmware interfaces, delivering stronger OS support, simpler software portability, and smoother enterprise integration. Building on this foundation, Jetson Thor now supports a unified NVIDIA® CUDA® 13.0 installation across all Arm targets, streamlining development, reducing fragmentation, and ensuring consistency from server-class systems to Jetson Thor.
The manual flashing instructions have slightly changed because of Thor using SBSA architecture. Please follow the manual flashing instructions carefully.
There is no more SD Card image for Jetson Orin Nano Developer Kit. Use the unified ISO image to flash the developer kit using a USB stick. Follow the instructions on Getting Started Guide.
If you’re re-installing JetPack 7.2.1 using ISO on an already installed system, please carefully follow the instructions in the Getting Started Guide.
