L4T 36.4.4 l4t_initrd_flash.sh fails in offline mode

I’m running l4t_initrd_flash.sh per Workflow 2 in tools/kernel_flash/README_initrd_flash.txt

./tools/kernel_flash/l4t_initrd_flash.sh --no-flash jetson-orin-nano-devkit-super-nvme nvme0n1p1

When a device is connected in recovery mode, this works fine. In offline mode with all the environment variables set, it fails. The process for getting the correct env variables was taken from Flashing Support — NVIDIA Jetson Linux Developer Guide

export BOARDID=3767
export BOARDSKU=0005
export FAB=300
export BOARDREV=T.1
export CHIP_SKU=00:00:00:D5

export RAMCODE=2

I’m attaching the two full logs in case they help…

fails: build-offline.log (41.6 KB)
works build-recovery.log (214.6 KB)

And forgot to mention… Host is Ubuntu-22.04 and I’m working with the Orin Nano 8gb Super official Devkit.

Hi,

Please try these commands instead

Thanks

That produced the same error. I think the issue is RAMCODE_ID.

The instructions say to use RAMCODE_ID=$( ./chkbdinfo -R chip_info.bin_bak) which produces 00:00:00:02 but the script fails when it tries to convert that to an int using the standard python int() function. The rest of the examples in the Developer Guide show RAMCODE_ID being a single digit number, not a hex string so I set RAMCODE_ID=2 and that worked.

So I think you probably need to fix the instructions related to setting the environment variables.

From the Developer Guide:

$ cd bootloader
$ BOARDID=$(./chkbdinfo -i cvm.bin)
$ BOARDSKU=$(./chkbdinfo -k cvm.bin)
$ FAB=$(./chkbdinfo -f cvm.bin)
$ BOARDREV=$(./chkbdinfo -r cvm.bin)
$ CHIP_SKU=$(./chkbdinfo -C chip_info.bin_bak)
$ RAMCODE_ID=$( ./chkbdinfo -R chip_info.bin_bak)
$ RAMCODE=$(echo "ibase=2; ${RAMCODE_ID//:/}" | bc)

Are all the variables actually needed? Most of the instructions where the variables are included on the command line just have the first 4.

Generally just the first 3 should be fine.

export BOARDID=3767
export BOARDSKU=0005
export FAB=300

RAMCODE is defined by hardware during runtime, so should not define it before flash.

Thanks @WayneWWW Yeah I just tried it with those 3 and it worked fine. tools/kernel_flash/README_initrd_flash.txt seems to have better info than the Developer Guide.
