getting this,it looks mismatch here
Can you use the other methods that connect the device with host to generate BUP? Let the host to directly read the info from target may generate the correct one.
i put the device in recovery mode and run below command to genrate BUP
sudo ./build_l4t_bup.sh jetson-tx2-4GB mmcblk0p1
i am getting below error

what could be the issue?
Hmm… looks weird. Let me try this on my device.
Device is fused board. what does it mean?
Device is fused board. what does it mean?
That does not matter. All the modules sold in the market are fused.
What is customized on your board so far? I mean diff with pure jetpack release.
so we have download SDK 32.4.3 and compiled own kernel,device tree uboot as per our custom board design for Tx2 4GB and flashing it.
did you check at your end,is it working?? it is not board specific,right?
Hi anupam.kumar,
We can’t reproduce your issue.
List our steps for you reference:
is this fine
root@localhost:/home/ubuntu# sudo nv_update_engine --enable-ab
Nvidia A/B-Redundancy Update tool Version 1.2
enabling A/B redundancy
Enable A/B command failed. It could be due to A/B being enabled already.
Error: Enable A/B redundancy failed!

offset size
/dev/mmcblk0boot1 0x3fe000 0x2000
also /dev/mmcblk0boot1 we are using to keep uboot enviornment variable in our custom board…does it cause a issue?
Yes, it is possible.
i reflash the board and then again trying to update using BUP

it is failing in MB2,other above logs are fine or it has issue?
Could you post every commands you are using on both host and device side for us to review?
And can we also confirm there is no other customization anymore? This is just happened to pure jetpack.
when i removed uboot customization i am able to update the BUP in my board.
my requirment is to only update uboot using ota.
i see these files are genertaed in payload_t18x directory
bl_only_payload bl_update_payload kernel_only_payload
i think kernel_only_payload will only update my uboot only,can you please confirm i have to install it in my board.we have to copy it in /opt/ota_package and run sudo nv_update_engine --install or any other command.
===========regarding Uboot enviorment variable i was keeping it in mmcblk0boot1 that is causing issue…
i see UBENV partition in flash.xml file of bootloader but i am not able to see this partition on board,can you please guide how i can identify which mmc partition it is using.
The updater will update every bootloader component. So you have to make sure other components are using correct content too.
There are other easier method if you only want to update uboot. For example, directly dd a signed uboot image to the partition.
As for your new question, we will check on your new topic.
so my new query is that like kernel and device tree can we make debian package for this bootloader also and can we update ??
apt-get install --reinstall nvidia-l4t-3d-core
nvidia-l4t-apt-source
nvidia-l4t-bootloader
nvidia-l4t-camera
nvidia-l4t-configs
nvidia-l4t-core
nvidia-l4t-cuda
nvidia-l4t-firmware
nvidia-l4t-graphics-demos
nvidia-l4t-gstreamer
nvidia-l4t-init
nvidia-l4t-initrd
nvidia-l4t-initrd
nvidia-l4t-jetson-io
nvidia-l4t-jetson-multimedia-api
nvidia-l4t-kernel
nvidia-l4t-kernel-dtbs \
Yes, you can update those debian package. Please refer to Debian website to get more familiar with deb tool.
so how this A/B mechnism work during OTA update…new image is flashed in A or B partition or in both partition…and when next time device boots it boot from A or B…can you please guide here
It depends on which active slot you are using. I already posted the document so not going to do that again.
The UART log will also tell you the answer.

can you please help here
hmm… can you always share what you’ve tried or modified in this attempt when you ask a question?
You just shared a log and not tell other people what you modified. How is it possible for others to help you if you only share such information?
