Unable to Switch to Force Recovery Mode

Inquiry:
I plan to upgrade from JetPack 5.2 to JetPack 6 in order to use CUDA 12. I believe it is necessary to enter recovery mode for the setup, but the device boots normally instead.

1. I press the central Force Recovery button while inserting the power cable before powering on, but the device does not transition to recovery mode and the OS boots normally.
2. I attempt to switch to Force Recovery Mode by executing the following command, but the OS still boots normally:
   $ sudo reboot --force forced-recovery

Is it possible that UEFI settings have changed and are preventing the device from entering recovery mode? Alternatively, is there a way to use CUDA 12 without using Recovery Mode?

Thank you for your support.

Hi ysugi,

There’s no Jetpack 5.2 yet. Do you mean Jetpack 5.1.2?
Please share the result of the following command on your devkit

$ cat /etc/nv_tegra_release
$ cat /etc/nv_boot_control.conf

Did you connect Type C cable when you try to enter into force recovery state?

Please connect TypeC port with your host first → Press REC button → Plug power cable → Release REC button → Run lsusb from host to check if the devkit is recognized

Thank you for your response.

I had the wrong version. It was JetPack 5.1. Here are the results of the commands:

cat /etc/nv_tegra_release
# R35 (release), REVISION: 2.1, GCID: 32413640, BOARD: t186ref, EABI: aarch64, DATE: Tue Jan 24 23:38:33 UTC 2023

cat /etc/nv_boot_control.conf
TNSPEC 3701-500-0005-M.0-1-1-jetson-agx-orin-devkit-
COMPATIBLE_SPEC 3701--0005--1--jetson-agx-orin-devkit-
TEGRA_LEGACY_UPDATE false
TEGRA_BOOT_STORAGE mmcblk0
TEGRA_EMMC_ONLY false
TEGRA_CHIPID 0x23
TEGRA_OTA_BOOT_DEVICE /dev/mtdblock0
TEGRA_OTA_GPT_DEVICE /dev/mtdblock0

It seems that the device does not enter recovery mode if the Ubuntu host and Jetson are not properly connected. Based on this hint, I reviewed the setup and found that I had inserted the cable incorrectly.

I should have used the No.10 USB Type-C port, but I was connecting to the Ubuntu host using the No.12 USB Type-A ports. Jetson AGX Orin Developer Kit User Guide - Hardware | NVIDIA Developer
