We can’t get the emmc/UFS device’s information. We find a devices named /dev/vblkdev2 ,May it be UFS? but we cannot edit it.

Hello,

Thanks for visiting the NVIDIA Developer Forums.
To ensure better visibility and support, I’ve moved your post to the Jetson category where it’s more appropriate

Cheers,

Hi evelyn.xie,

Are you using the devkit or custom board for AGX Orin?
What’s the Jetpack version in use?

Please share the log as text file instead of the screenshot.
You can simply run lsblk to check the current device.

Are you using DriveOS rather than L4T?

How did you flash AGX Orin devkit?

I am using DriveOS, which was obtained from this path.

This development kit also came with this system when it was delivered to us from the factory. Can this system not perform tests on eMMC or UFS?

Dear @evelyn.xie ,
vdevblk0 is eMMC and vblkdev2 is UFS.
