Visual NAND Reconstructor 8.2
Dear Users,
We are glad to release Visual NAND Reconstructor 8.2!
Due to growing capacities of flash memories we constantly try to improve and optimize speed of all the steps of data processing workflow.
In this update we have redesigned the algorithms for AI XOR generation to make it faster and more efficient. Now, in cases with FC and SM controllers, it takes minutes instead of hours to find a key.
On some AU controllers where it was not possible to generate full key it is now possible even if key is inconsistent within the block.
You can now generate SM XOR key for the cases with bad columns, no manual work required.
New NAND protocols have also been added to software.
Here’s the full list of new features:
AI XOR generation - speed and quality breakthrough
All AI XOR generators have been completely re-designed with speed increase 10x – 1000x times and higher (depends on particular case).
The mathematical algorithms behind the process were significantly improved. Improvement affects all AI XOR generators.
AI XORs - improvements by vendors
-
The Silicon Motion SM3281L controller, has become extremely popular these days. When a device with this controller encounters bad columns, which is a common issue, the traditional approach of using binary XOR keys from a database is ineffective. This is because each of these devices has a unique XOR key based on the distribution of bad columns. Currently, Visual NAND Reconstructor is the only tool capable of handling this automatically. All you need to do is just to remove Bad columns firstly with BCR element, then connect AI SM XOR and it will generate the key designed specifically for your device fully automatically. In case every plane uses different XORs, the dump has to be divided by planes and treated separately. We hope now most of those cases will be solved in more automatic manner and lot of time will be saved.
-
Improved AI FC XOR generation on Spare Area.
Updated algorithm of SA XOR generation on FC controllers allow to precisely unxor SA and validate it.
-
AI XOR for AU controllers can now precisely generate key in cases when XOR is not continuous within the block.
New NAND Protocols
We have added two new protocols for the Hybrid Micron NAND memory chips (e.g. ID 2C844863):
-
Async SDR Micron HybridX1
-
WL SDR Micron HybridX3
Block Manager
We have optimized work of Block Manager and added several useful features
-
Improved interface -
New predefined marker “FS signature” which will always show the block with file system using MBR/Boot marker
