Hi liwang54321,

Are you using standalone x86 Ubuntu18.04 or 20.04 as your host PC?

You could refer to Workflow 11 of Linux_for_Tegra/tools/kernel_flash/README_initrd_flash.txt.
If you wants to generate image w/o flash, you could use the following command:

$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --no-flash \
            --external-device nvme0n1p1 \
            -c ./tools/kernel_flash/flash_l4t_external.xml \
            --external-only --append jetson-xavier-nx-devkit external

@KevinFFF

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --no-flash \
            --external-device nvme0n1p1 \
            -c ./tools/kernel_flash/flash_l4t_external.xml \
            --external-only --append jetson-xavier-nx-devkit external

Thank you, this is generated successfully, why is that?

[liwang54321]

I see that the readme can be set to -S

Thank you, this is generated successfully

So, could you use that command to generate expected image?

There are many Workflow from README_initrd_flash.txt could be referred to.
Just select the one for your use case.

-S parameter is used to specify the size of rootfs instead of the default size (ROOTFSSIZE) configured in xml.
