Nvidia AGX Orin R36.3

聽說JP 6之後，build Kernel比較複雜@@
不需要display，所以好像省了很多事@@，ex: OOT

R36.3,下載 

1. Driver Package (BSP) Sources
2. Driver Package (BSP)
3. Bootlin Toolchain gcc 11.3

解壓

1. jetson_linux_r36.3.0_aarch64.tbz2 -> Linux_for_Tegra
2. cp public_sources.tbz2 temp; public_sources.tbz2 -> Linux_for_Tegra

前置作業

1. public_sources.tbz2的三個檔案取出
• kernel_src.tbz2
• kernel_oot_modules_src.tbz2
• nvidia_kernel_display_driver_source.tbz2
2. 三個檔案都解壓到Linux_for_Tegra/soruce下

build Kernel

$ export ARCH=arm64
$ export CROSS_COMPILE=${PWD}/toolchains/aarch64--glibc--stable-2022.08-1/bin/aarch64-buildroot-linux-gnu-
$ export LOCALVERSION="-rt-tegra"
$ export WORK=AGX_Orin/r36.3/Linux_for_Tegra

跳過oem-config流程(執行一次就行）
rer:NVIDIA Jetson系统初始化设置
$ sudo ./tools/l4t_create_default_user.sh -u user_name -p password --accept-license

$ cd $WORK/source
$ make -C kernel   //source/kernel/kernel-jammy-src/arch/arm64/configs/defconfig
..
..
kernel/kernel-jammy-src/arch/arm64/boot/Image <-這個位置要跟Linux_for_Tegra/kernel/Image一樣

$ cp kernel/kernel-jammy-src/arch/arm64/boot/Image Linux_for_Tegra/kernel/

燒到板子...QuickStart, how to flash

Press RCM, 接上電
Data port, 離電源(圓頭)比較遠的
debug port, 拔掉

lsusb:
    Bus 003 Device 013: ID 0955:7023 NVIDIA Corp. APX
    //7023 for Jetson AGX Orin (P3701-0005 with 64GB)
    //7523 for Jetson Orin Nano (P3767-0003 and P3767-0005 with 8GB)

$ sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1  //此方法是寫入eMMC

This command will return the model name

cat /proc/device-tree/model

燒到SSD, 換Jetson Orin NX (document)

$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
  -c tools/kernel_flash/flash_l4t_t234_nvme.xml -p "-c bootloader/generic/cfg/flash_t234_qspi.xml" \
  --showlogs --network usb0 jetson-orin-nano-devkit internal

過程中碰到...
MB2 Applet version 01.00.0000
Parsing board information failed.
Error: failed to generate images
Cleaning up..

解法：
$ sudo BOARDID=3767 BOARDSKU=0003 FAB=300 ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
  -c tools/kernel_flash/flash_l4t_t234_nvme.xml -p "-c bootloader/generic/cfg/flash_t234_qspi.xml" \
  --showlogs --network usb0 jetson-orin-nano-devkit internal
