Generating temp_initrdflash/bootloader0 without flashing

Hello,
I have been taking the temp_initrdflash/bootloader0 and rootfs and compressing this to distribute.
(if this is sub optimal for creating a kernal image for flashing please let me know)

The issue I have is temp_initrdflash/bootloader0 isn’t created until I flash the ORIN AGX
is there a way to create this without needing to be connected to an ORIN?

I have tried with --no-flash --keep --sparse arguments but still don’t get the desired directory.

Any help would be appreciated.

This is the command I currently use to create the bootloader0 folder, but it requires me to flash an ORIN

    sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --keep --sparse --external-device nvme0n1p1 -p "-c ./bootloader/t186ref/cfg/flash_t234_qspi.xml" \
    -c $ROOT/flash_l4t_nvme.xml -S 1500GiB --showlogs --network usb0  jetson-agx-orin-devkit internal

also just a general question how does temp_initrdflash/bootloader0 differ from bootloader?

seems I can’t generate the temp_initrdflash/bootloader0 without connecting to RCM ORIN
just wondering if I actually need this to flash if I want to use sparse image.

Hi kip.kerluke,

Are you using the devkit or custom board for AGX Orin?
What’s the Jetpack version in use?

Adding --no-flash in the flash command should work in your case. Please do not add --flash-only here.

Please also refer to Workflow 2: How to generate images first and flash the target later. in README_initrd_flash.txt for details.

Hi Kevin.

I am using an orin agx devkit. I have run that command with --no-flash and I dont have the temp_initrdflash/bootloader0 folder

My objective is to be able to compile/build an OS image for distribution to other team members, so if I don’t need temp_initrdflash/bootloader0 for this then maybe I’m on the wrong path. but when I run with --flash-only it hangs without these files"

they seem to only generate when actually flashing an ORIN AGX

What’s your Jetpack version in use?

It seems you want to prepare the package for others to use.
Have you also referred to backup/restore scripy?
You can find more details in <Linux_for_Tegra>/tools/backup_restore/README_backup_restore.txt

Or you can refer to To clone a Jetson device and flash if your modifications are only in rootfs.
