Hi, I get following error: CBB fault on my xavier a (pegasus). How can I revive it ? If not, is there a way to get the data from internal disk back ?

Dear @erwin.rademakers,
May I know if the target is used in office premises or car?

We use it on an amr.

May I know what you mean by amr?

autonomous mobile robot

Dear @erwin.rademakers,
The data can not be recovered. Could you please check if you can reflash the target?

Can I only reflash xavier A ?

@erwin.rademakers yes. When flash using using sdkmanager( Point 5 in Install DRIVE with SDK Manager :: DRIVE Platform Installation Guide with NVIDIA SDK Manager) please select just Flash A instead of Flash A+B in flashing step

I reflashed A, even selected to wipe the user data, but got exactly the same error.

Dear @erwin.rademakers,
Do you see flashing is successful message? This “CBC fault” error is noticed in first boot after flash?

Flashing was successful. The error came after first boot after flashing.
