Notes on programming/interfacing with Jetson Orin hardware.
=== Upgrading AGX to Jetson Linux 36.3 ===
# Upgrading AGX to Jetson Linux 36.3==== BSP approach (avoids SDK Manager) ====
## BSP approach (avoids SDK Manager) * Requires Ubuntu 22.04. Very unhappy to work on Gentoo. * Requires Intel/AMD 64bit CPU. * Download "Driver Package (BSP)" from [https://developer.nvidia.com/embedded/jetson-linux here]* Unpack (as root, get used to doing most of this as root), preserving privileges** <code>tar xjpf ...</code>* Download "Sample Root Filesystem" * Unpack (as root..) into rootfs directory inside of the BSP archive above.* Run <code>sudo ./tools/l4t_flash_prerequisites.sh</code>* Run <code>./apply_binaries.sh</code> from the BSP ** Note: If apply_binaries (or frankly, anything, this is brittle) fails, remove and recreate rootfs - the OS might be left in an unbootable state. * Reboot AGX into "Recovery Mode" - hold the recovery button and reset button, release simultaneously ((sic) reset first?)* Connect USB-C cable to the debug port ("front" USB-c) * Nvidia AGX device should appear in the <code>lsusb</code> under NVIDIA CORP. APX* Run <code>./flash.sh </code> Different options for different usecases(https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/IN/QuickStart.html#in-quickstart)Jetson AGX Orin Developer Kit (eMMC):
