How to flash custom rootfs

Hello, I am using Jetson Orin Nano Devkit with L4T35.4.1, nvme sotrage. I am trying to flash image with custom rootfs. I know the ‘backup_retore’ tools from JP, that’s not I am trying.

I have made a copy of running Jetson System as a folder (not as a tar), replaced the default rootfs in Linux_for_Tegra directory and tried normal flash with

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -p “-c ./bootloader/t186ref/cfg/flash_t234_qspi.xml” -c ./tools/kernel_flash/flash_l4t_t234_nvme.xml --showlogs --network usb0 jetson-orin-nano-devkit nvme0n1p1

I have added a lot of things. So now the default rootfs size is 7.6 Gb and custom rootfs size is around 11 Gb.

Belos is the end of debug output

[ 222]: l4t_flash_from_kernel: Successfully flash the qspi
[ 222]: l4t_flash_from_kernel: Failed to write to APP
[ 222]: l4t_flash_from_kernel: The device size indicated in the partition layout xml is smaller than the actual size. This utility will try to fix the GPT.
[ 222]: l4t_flash_from_kernel: Error flashing external device
Flash failure
Cleaning up…

But surprisingly the newly created system.ing.raw is the same as default 59.1 GB.

@DavidDDD Thanks for that. I saw that too and tried this method. But this method is also not working. I also used -S perameter with 60GiB, 30GiB although the modified rootfs is about 11Gb. My nvme is 128 Gb. But none of this work.

I have looked into this issue and modifed the command for 35.4.1 but still not working.

I rename the orginal rootfs, now I can not flash that also.

Am I missing somehting ?
