Hello,

jetapck ver. : R32 (release), REVISION: 7.2
jetson module : Xavier NX ddr 16GB

I expect that dmesg say like below.

dmesg | head -5
[    0.000000] Booting Linux on physical CPU 0x0
[    0.000000] Linux version 4.9.253-tegra ( my information ) (gcc version 7.3.1 20180425 [linaro-7.3-2018.05 revision d29120a424ecfbc167ef90065c0eeb7f91977701] (Linaro GCC 7.3-2018.05) ) #1 SMP PREEMPT Sun Apr 17 02:37:44 PDT 2022

[    0.000000] OF: fdt: - 80000000 ,  2c000000

but, like this

dmesg | head -5

 15 # When testing a custom kernel, it is recommended that you create a backup of
 16 # the original kernel and add a new entry to this file so that the device can
 17 # fallback to the original kernel. To do this:
 18 #
 19 # 1, Make a backup of the original kernel
 20 #      sudo cp /boot/Image /boot/Image.backup
 21 #
 22 # 2, Copy your custom kernel into /boot/Image
 23 #
 24 # 3, Uncomment below menu setting lines for the original kernel
 25 #
 26 # 4, Reboot
 27 
 28 # LABEL backup
 29 #    MENU LABEL backup kernel
 30 #    LINUX /boot/Image.backup
 31 #    INITRD /boot/initrd
 32 #    APPEND ${cbootargs}

Could anyone tell me how to resolve this issue?

Additionally, After flashing jetson in fresh, then if I do apt update and at upgrade, What is changed? Can I see upgraded item’s list?
Can I rollback previous state(before doing apt upgrade)?

Thank you.

There is a bug in 32.7.2 cboot. Need to apply this patch.
