New Codeword Analysis

Can anyone explain how to use the new codeword analysis tool in VNR?
I have a 20-82-00162-3 controller which I think is pretty new as I cannot find references to it.
I may have the same issue with XOR.

It is in the new version of VNR, it is one of the enhancements.

Pretty sure that controller is encrypting, so you won’t find XOR.

Ahh. That explains it. I guess i'll be on the hunt for a donor then. Thanks Sean.

What was the issue with the device originally?

Broken connector and some damage to the board unfortunately.

If the damage is not repairable or you cannot tap into the broken tracks, then as you say you’ll need a donor to switch the NAND chip onto.

Yes we spent the best part of 4 hours trying to get this to read.
