*  Step 1: Generate flash packages *
*                                  *
************************************

Usage: /home/troels/nvidia/nvidia_sdk/JetPack_4.6_Linux_JETSON_AGX_XAVIER_TARGETS/Linux_for_Tegra/tools/kernel_flash/l4t_create_images_for_kernel_flash.sh -N <IPaddr>:/nfsroot [-u <keyfile>] <board-name> <rootdev>
Where,
    -u <PKC key file>            PKC key used for odm fused board.
    -v <SBK key file>            SBK key used for encryptions
    -N <IPaddr>:/nfsroot         Indicate where the IP and the location of the NFS root file system
    -n nfsargs                   Static nfs network assignments
                                 <Client IP>:<Server IP>:<Gateway IP>:<Netmask>
    -p <option>                  Pass options to flash.sh when generating the image for internal storage
    <board-name>                 Indicate which board to use.
    <rootdev>                    Indicate what root device to use
    --no-flash                   Stop the flash script from flashing the target to NFS
    --flash-only                 Flash to NFS root file system without creating the image
    --external-device <dev>      Generate and/or flash images for the indicated external storage
                                 device. If this is used, -c option must be specified.
    --external-only              Skip generating internal storage images
    --usb-instance               Specify the usb port where the flashing cable is plugged (i.e 1-3)
    -c <config file>             The partition layout for the external storage device.
    -S <size>                    External APP partition size in bytes. KiB, MiB, GiB short hands are allowed,
                                 for example, 1GiB means 1024 * 1024 * 1024 bytes. (optional)
    -t                           Skip to generate flash package tarball. This option can be used
                                 for host that is also used for NFS host.


With --external-device options specified, the supported values for <dev> are
    nvme0n1
    sda

Examples:
    1) Flash jetson-xavier:
        sudo ./l4t_create_images_for_kernel_flash.sh -N 192.168.0.21:/data/nfsroot jetson-xavier mmcblk0p1

    2) Flash jetson-xavier and the attached external storage device:

        sudo ./l4t_create_images_for_kernel_flash.sh --external-device nvme0n1
            -c external_storage_layout.xml
            -S 5120000000
            -N 192.168.0.21:/data/nfsroot
            jetson-xavier
            mmcblk0p1

The results of the command is:
a) Generate images for external device based on external_storage_layout.xml and
set the size of the APP to ~ 5GB (5120000000 bytes)

b) Generate images for internal device based on the given <board-name> and
<rootdev>. More specifically, it internally uses the following command:
    ./flash.sh --no-flash --sign jetson-xavier mmcblk0p1

c) Then the device is RCM boot to NFS

The uuid of boot partition for external storage device is generated each time
and saved in Linux_for_Tegra/bootloader/l4t-rootfs-uuid.txt.ext.
