New Jetpack 5: still broken


The fix for the odmfuseread script promised here only fixes the second part (i.e. the crash).
However, in the new JetPack release, the script is still broken, there are 2 issues:

  1. Python3 issue:
    Please update line 1946 from:
    for file_nodes in xml_tree.getiterator(‘file’):
    for file_nodes in xml_tree.iter(‘file’):

  2. Incomplete help text:
    Please add to the usage description the board Id 0x23 for the Jetson Orin Nano Devkit.


hello business37,

may I also know which release version you’re tested with?

I used Jetson_Linux_R35.5.0_aarch64

hello business37,

we’ve tested on JP-5.1.3 (r35.5.0) to check fuse variables via without failures.
may I know what’s your commands, and what’s the error messages reported?

ya… this is out-of-date,
let me submit change update to address it.

The file that needs fixing is bootloader/
The command I’m running is:

$ sudo ./ -i 0x23 -k ~/jetson-secureboot/keys/pkc.pem -S ~/jetson-secureboot/keys/sbk.key jetson-orin-nano-devkit

And here is the full output:

./ --chip 0x23 --applet “/home/sschorr/Jetson_Linux_R35.5.0_aarch64/Linux_for_Tegra/bootloader/mb1_t234_prod.bin” --skipuid --cfg readinfo_t234_min_prod.xml --dev_params tegra234-br-bct-diag-boot.dts --device_config tegra234-mb1-bct-device-p3767-0000.dts --misc_config tegra234-mb1-bct-misc-p3767-0000.dts --bins “mb2_applet applet_t234.bin” --cmd “dump eeprom cvm cvm.bin; dump custinfo custinfo_out.bin; reboot recovery” --encrypt_key “/home/sschorr/jetson-secureboot/keys/sbk.key” --key “/home/sschorr/jetson-secureboot/keys/pkc.pem”

As the message says, there is no method “getiterator”, it needs to be replaced by calling “iter”.


may I also know your host environment, for example, is it ubuntu-20 or 22?

I’m running Ubuntu 22.04.4 LTS, with Python 3.10.12

hello business37,

it should be an OS issue there.

as mentioned in Secure Boot section.

An X86 host running Ubuntu 18.04 LTS, or 20.04 LTS.

we’ve also tested again on Ubuntu-20.04 and Ubuntu-18.04 to verify without failures.
