Xavier NX capsule update failed

I saw the device reboot twice

I execute “sudo nvbootctrl dump-slots-info” command
log:
Error: config COMPATIBLE_SPEC not found in /etc/nv_boot_control.conf

The bootloader slot has not changed！

Hi,

@easyzoom

Error: config COMPATIBLE_SPEC not found in /etc/nv_boot_control.conf

I think that might be an issue here?
What do you have in /etc/nv_boot_control.conf? How did you flash the device originally?

Would it boot with slot B if you manually change it?

[easyzoom]

Hello,
nv_boot_control.conf:
TNSPEC 3668-100-0001-H.0-1-2-jetson-xavier-nx-
TEGRA_CHIPID 0x19
TEGRA_OTA_BOOT_DEVICE /dev/mtdblock0
TEGRA_OTA_GPT_DEVICE /dev/mtdblock0

I flashed the device in a customized way
I execute command is “sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --network usb0 --massflash 5”

Do I add the COMPATIBLE_SPEC parameter manually?

@easyzoom

I flashed the device in a customized way
I execute command is “sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --network usb0 --massflash 5”

I don’t know how you generated the flashing package.
Please re-flash with flash.sh and repeat your workflow.

sudo ./flash.sh jetson-xavier-nx-devkit internal

[easyzoom]

I reverted my changes and generated new nv_boot_control.conf

TNSPEC 3668-301-0001-F.0-1-2-jetson-xavier-nx-
COMPATIBLE_SPEC 3668-301-0001-F.0-1-2-jetson-xavier-nx-
TEGRA_LEGACY_UPDATE false
TEGRA_BOOT_STORAGE mmcblk0
TEGRA_EMMC_ONLY false
TEGRA_CHIPID 0x19
TEGRA_OTA_BOOT_DEVICE /dev/mtdblock0
TEGRA_OTA_GPT_DEVICE /dev/mtdblock0

I re-executed the capsule update operation, but it still failed.

sudo nvbootctrl dump-slots-info
Current version: 35.4.1
Capsule update status: 0

Active bootloader slot: A

@DaveYYY

Would it boot with slot B if you manually change it?

Then is this working?
Is it still the same if you flash the device again with the default BSP?

[easyzoom]

What do I need to change manually?
I have used the default bsp flash the device，the result is still the same

[DaveYYY]

Hi,

We’ll verify locally and reply to you later.
Thanks.

[easyzoom]

I solved the problem, thank you

[DaveYYY]

How did you do it?

[easyzoom]

I didn’t restore the jetson_board_spec.cfg file correctly

[DaveYYY]

OK, that’s fine.
Glad to hear you solved it.
