Hi,

We have a official devkit xavier , added an 500GB SSD (Nvme) to it (J1 interface).
I flashed the system in NVME mode using SDKManager, and enable redundancy with “sudo nv_update_engine --enable-ab”,and generat the Bootloader Update Payload due to official document,but when I use command " sudo nv_update_engine -i bl-only --payload bl_update_payload",I encountered an error:

 sudo nv_update_engine -i bl-only --payload bl_update_payload

Please share us what is the content inside your /etc/nv_boot_control.conf.

Hi WayneWWW,

Thanks for your reply!

My " /etc/nv_boot_control.conf" is :

TNSPEC 2888-400-0004-K.0-1-2-jetson-xavier-nvme0n1p1
TEGRA_CHIPID 0x19
TEGRA_OTA_BOOT_DEVICE /dev/mmcblk0boot0
TEGRA_OTA_GPT_DEVICE /dev/mmcblk0boot1

Thanks!

BR.

What was your command to generate the BUP blob?

Hi WayneWWW,

Thanks for your reply!
The command is :
sudo FAB=400 BOARDID=2888 FUSELEVEL=fuselevel_production BOARDSKU=0004 BOARDREV=K.0 ./build_l4t_bup.sh jetson-xavier nvme0n1p1

Thanks!

Hi,

Could you describe the whole process of how you flash your nvme with sdkm?

Also, please check if this service is running fine.

nv-l4t-bootloader-config.service

Hi WayneWWW,

Thanks for your reply!

I’m going to try it again. If it happens again, I’m going to repeat the steps.

Thanks!

Hi WayneWWW,

I tried several times, but I couldn’t reproduce the problem. I didn’t know whether I was happy or unhappy.

“nv-l4t-bootloader-config.service” as follow:

If the problem recurs, I’ll let you know.

Now I can use BUP to upgrade BootLoader normally, but I don’t know how to switch rootfs.

I successfully flashed NVME SSD using command " sudo ROOTFS_AB=1 ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1 -c ./tools/kernel_flash/flash_l4t_nvme_rootfs_ab.xml -S 10GiB --showlogs jetson-xavier nvme0n1p1 ", I can see "/dev/nvme0n1p1 " and “/dev/nvme0n1p2”, "/dev/nvme0n1p1 " is current APP partition ,how can I switch to another one?

Thanks!
BR.
