Flash Step

Enter Recovery mode

When it comes to using 'flash.sh', make sure you enter the Recovery mode first.

1. Connect to computer via M-USB1.
2. Plug the storage you want to flash system image.
3. Press 'Recovery' button and 'Reset' button at the same time.
4. Release 'Reset' button.

Flash command

Please flash using Nvidia script for ORIN series

$ cd <nvidia_folder>/Linux_for_Tegra/
$ ls ./tools/kernel_flash/l4t_initrd_flash.sh
./tools/kernel_flash/l4t_initrd_flash.sh

Base on your modules, select the <board name> for script.

Base on your condition, select the <storage name> for script.

Flash demo image

1. • Download TechNexion TEK-ORIN products demo image from HERE
     
   • Download Jetson ORIN NANO EVK demo image from HERE
     

   Make sure you download the image with the boot device you need.

2. Unzip the file

3. Connect the storage to computer and flash to block device

$ lsblk
$ sudo bmaptool copy <FILE.bz2> /dev/<BLOCK_DEVICE>

3. Plug the storage back to device and boot.

DO NOT create new system.img, flash only

You can follow section: Create new system.img, DO NOT flash to create system.img.

# --flash-only
$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh \
        --external-device <storage name> -c tools/kernel_flash/flash_l4t_external.xml \
        -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
        --showlogs --flash-only --network usb0 <board name> internal

./tegraflash.py ...

kernel_dtb tegra234-p3767-0003-tek-orin-a1.dtb"  
--ramcode 2

Create new system.img, and flash

$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh \
        --external-device <storage name> -c tools/kernel_flash/flash_l4t_external.xml \
        -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
        --showlogs --network usb0 <board name> internal

Create new system.img, DO NOT flash

# --no-flash
$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh \
        --external-device <storage name> -c tools/kernel_flash/flash_l4t_external.xml \
        -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
        --showlogs --no-flash --network usb0 <board name> internal

You can flash to device follow by section:DO NOT create new system.img, flash only.

Backup and restore currect device image

Download backup/ restore script of Jetpack R35.4.1.
Use it to replace the files in Linux_for_Tegra/tools/backup_restore/ .

backup

# -b: jetson-orin-nano-devkit for EVK
#     jetson-orin-nano-devkit-nvme for TEK-ORIN series
# -e: mmcblk1p1 for ORIN-EVK
#     nvme0n1 for TEK-ORIN series
$ sudo ./tools/backup_restore/l4t_backup_restore.sh -e <storage name> -b <board name>

restore

# -b: jetson-orin-nano-devkit for EVK
#     jetson-orin-nano-devkit-nvme for TEK-ORIN series
# -e: mmcblk1p1 for ORIN-EVK
#     nvme0n1 for TEK-ORIN series
$ sudo ./tools/backup_restore/l4t_backup_restore.sh -e <storage name> -r <board name>

Create raw disk image (can be dd into storage)

Download script has the tweaked disk image creator ready.

$ ls tools/jetson-disk-image-creator.sh 
tools/jetson-disk-image-creator.sh

# -o: output file name
# -b: board conf name
#       TEK6100-ORIN-NX/ TEK6040-ORIN-NANO ...
# -d: Boot device name
#       NVMe/ USB/ SD
$ sudo ./tools/jetson-disk-image-creator.sh \
        -o <image_name>.img -b <board name> -d <Boot device>

ex1: TEK6100-ORIN-NX with NVMe boot

$ sudo ./tools/jetson-disk-image-creator.sh \
    -o TEK6020-ORIN-NANO_20240504_NVMe_disk.img \
    -b tn-tek6020-orin-nano -d NVMe

ex2: VLS3-ORIN-EVK with SD boot

$ sudo ./tools/jetson-disk-image-creator.sh \
    -o VLS3-ORIN-EVK-VLS3_20240504_SD_disk.img \
    -b tn-vls3-orin-evk-vls3 -d SD

Now you can deploy the image into you device follow section: Flash demo image .

Flash new pinmux image

0) Edit the xlsm pinmux file via windows environment.

<nvidia_folder>/Linux_for_Tegra/sources/TEK-ORIN_Orin-Nano_pinmux/Jetson_Orin_NX_series_and_Orin_Nano_series_Pinmux_Config_Template.xlsm

Use the scroll bar right to select the pinmux of the cell(pin).

If done, click the above Macro(Generate DT file) to generate pinmux file.

1) Type the <name> twice.

tek-orin-a1 for TEK-ORIN series

You will see this result.

2) Copy generated dtsi to bootloader/ folder

$ sudo cp -rp Orin-tek-orin-a1-gpio-default.dtsi Linux_for_Tegra/bootloader/
$ sudo cp -rp Orin-tek-orin-a1-pinmux.dtsi Linux_for_Tegra/bootloader/t186ref/BCT/

4) Update NVIDIA QSPI for pinmux

follow the 'Create and flash new QSPI image only'.

Create and flash new QSPI image only

Just remove --external-device option

$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh \
        -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
        --showlogs --network usb0 <board name> internal

this also support the --no-flash and --flash-only option

$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh \
        -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
        --showlogs --flash-only --network usb0 <board name> internal

Those only update by file system

Those part below can't be changed by flash.sh.
Need to change the file by:

1. ssh (scp)
2. USB stick
   
   

Update new kernel Image

Copy from:

<nvidia_folder>/Linux_for_Tegra/sources/kernel/kernel-5.10/arch/arm64/boot/Image

Update new kernel modules

Copy from

<nvidia_folder>/Linux_for_Tegra/sources/kernel/modules/lib/

Update device tree

From:

<nvidia_folder>/Linux_for_Tegra/sources/kernel/kernel-5.10/arch/arm64/boot/dts/<target>.dtb

to device:

Change default device-tree

On device:

$ vi /boot/extlinux/extlinux.conf
LABEL primary
      MENU LABEL primary kernel
+     FDT /boot/<target>.dtb
      LINUX /boot/Image
      INITRD /boot/initrd
