BSB Missmatch error on AGX

Hi There,

I am trying to flash my Jetson Xavier AGX.

While flashing from Host PC, it throw me a error message pop-up as shown in image:
Error: “BSB Version Mismatch”

SDK Manager: Jetpack 5.0.2 [REV.1]

Can anyone help me with following details:
1> How to identify the correct BSB for my target device (AGX)?
2> From where to download the correct BSB for my device?
3> Is there any procedure to perform tis operation?
4> Do I need to delete the entire folder from my host PC and retry with new setup files along with correct BSB?

Any help to educate myself would be highly appreciate.


Hi vnawani,

The all components version are depends on BSP image version.
You can use JetPack-5.0.2 to Flash Jetson Orin device and install all components.

Answer questions:

  1. Use below command to check your target board BSP image version:
    $ head -1 /etc/nv_tegra_release
  2. Please reference: JetPack Archive | NVIDIA Developer
  3. Run SDK Manager to install BSP image and all components.
    If your target device is the correct BSP image version with JetPack, then you can skip flash image.
  4. Yes, you can delete folder first, then try again.

Hi @carolyuu :
Please help me to understand your answer.
I guess, BSP image version means L4T version… Is that correct?

I can read nv_tegra_release.
How can I verify target device correct BSP image version with JetPack?

So, the moral of the story is that the target device BSP image version should match with JetPack BSP image version to get rid of BSP missmatch version error… Is that correct?

Hi vnawani,

Yes, the target BSP image version need match with JetPack BSP version, then you can use the same JetPack version to install sdk components. If BSP image version is different with your target device, you will get mismatch errors.


$ head -1 /etc/nv_tegra_release 
# R35 (release), REVISION: 1.0, GCID: 31250864, BOARD: t186ref, EABI: aarch64, DATE: Thu Aug 11 03:40:29 UTC 2022

Check on your Jetson device, the BSP image version is R35.1.0.
Then you can check here: JetPack Archive | NVIDIA Developer
You will know L4T R35.1 = JetPack-5.0.2 , so you can use SDK Manager to install JetPack-5.0.2 sdk components on your Jetson device.

@carolyuu :

Thanks for this explanation… Its loud and clear and I understood now… Let me perform it soon and resolve it. If not and need a bit more support, I’ll get back you you.
Appreciate your prompt support.

Continuing the discussion from BSP Missmatch error on AGX:

Hi @carolyuu

Unfortunately this time also I am getting BSP miss-match error.

I checked my target device (Xavier AGX) and found BSP version R35.1, as shown below:

R35 (release), REVISION: 1.0, GCID: 31346300, BOARD: t186ref, EABI: aarch64, DATE: Thu Aug 25 18:41:45 UTC 2022

Stuff I did:

Step 1: I deleted two folders (sdkm_downloads & nvidia_sdk) from my host PC.
Step 2: I checked BSP version on my target device (Xavier AGX) and found R35.1. So I downloaded SDKManager “sdkmanager_1.8.2-10409_amd64.deb”

Step 3: Created 2 folders at location File-> Jetson-> Installations → created 2 folders (sdkm_downloads & nvidia_sdk).

Step 4: Open terminal on host PC and execute sdkmanager.

Step 5: It almost completed 99% download and then throw BSP missmatch error pop-up.

1> On Host PC sdkmanager face install error for “pi-lib-2.1.6-cuda11-x86_64-linux.deb”. Below are the details:

2> On target device (Xavier AGX): Check the below images as observation for your reference.

Can you suggest what can I do to get rid of this error?

Hi vnawani,

Can you try select flash image and install sdk components on target only like below?

Hi @carolyuu :
This is the current status.
Installation is getting freeze at 82.4%
Message pop-up appearing "Nsight Compute taking longer thn expected to install ".

I alrady clicked YES once. And this is the second time is showing it without any progess.
What you want me to click? YES or NO?
Check image below:


Hi vnawani,

Yes, please wait to continue install the package.

Hi @carolyuu,
So here is the outcome:

What you think can be the probable cause of these failures…?
Can we doubt the host PC or you think problem is something else?
Please do share your understanding about it…

Should I try to install old version or jetpack or reflash PCwith ubuntu… or completely change the location for (sdkm_downloads & nvidia_sdk folders or change the target device?
But I guess there is no point of doubting the target device (AGX) as the device is not reached the state of flashing. It more seems an issue on host PC side, isn’t it?
You understand this setup better then me. I’ll be waiting for your analysis… Kindly help me in this situation as I am struggling to ramp up this hardware since last one month now. Hope to here soon from you.

Hi vnawani,

What ubuntu version on your host PC? Ubuntu-18.04 or Ubuntu-20.04?
Please provide sdk logs and tar from below path:

@carolyuu : Mate, m using ubuntu v18.04.

I just restarted installation process. Now I am trying to install sdkmanager v1.8.3.

Before installation, I uninstalled all packages, restarted my host PC.
Let me know what can we do furter?

@carolyuu , As I just restarted the installation process, please give me few hours to install.
Ill provide you log details from /home//.nvsdkm soon…

Hi @carolyuu :
Finally, it got installed successfully mate… Thanks alot for all of ur support…
Issue was that I did not un-install before reinstalling. During 1st time installation, one of its package got broken and failed installation. This lead to installation failure everytime I tried.

This time I un-installed all packages and the proceed with new installation and it succeed.
Mate, we can close this conversation now… Thanks alot fro your support…
