Dear @erwin.rademakers,

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

8

Can I only reflash xavier A ?

9

@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

10

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

11

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

13

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

Dear @erwin.rademakers,
Could you attach the complete boot log?
