Hi,

Xavier NX won’t boot without an SD card installed.

There is no need of separating the flashing command and calling l4t_initrd_flash_internal.sh, and I don’t know how you come up with it.
Just use this:

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c ./tools/kernel_flash/flash_l4t_external.xml --showlogs --network usb0 jetson-xavier-nx-devkit nvme0n1p1

Hi Dave;
Okay, I’ll try this new command. But about ‘Xavier NX won’t boot without an SD card installed.’, I use sdkmanager to flash, no SD card , nvme is installed, it is possible to flash normally. after flash , xavier nx boot is fine; Thank you

Hi Dave:
I tried your script, but still failed, and the result should be the same; is there any other way?
Thank you

So do you have an SD card inserted?

Hi Dave:
There is no SD card installed at Flash. I think sdkmanager can flash successfully without SD card. There should be other ways to Flash without SD card. But I don’t know what the script is. Thank you.

Then please just use SDK Manager.

Hi Dave:
But I need to use scripts to flash. Sdkmanager is not convenient.

Hi,

It turns out that you need quotation marks for the -p option.
Please try again like

    sudo -E ./tools/kernel_flash/l4t_initrd_flash_internal.sh \
        --no-flash \
        --external-device nvme0n1p1 \
        -c tools/kernel_flash/flash_l4t_t194_nvme.xml \
        --showlogs \
        --network usb0 \
        -S 64GiB \
        -p "--no-systemimg -c bootloader/t186ref/cfg/flash_l4t_t194_qspi_p3668.xml" \

I’ve tested and confirmed it worked on my device. (Flashing NVMe drive without SD card)
Please either try again or see if you can get some clue from the serial console log.

Hi Dave:
