THESE ARE THE OFFICIAL XECUTER DRIVERS FOR NAND-X. THEY ARE COMPATIBLE WITH ALL VERSIONS OF NANDPRO INCLUDING V3.
Cisco anyconnect secure mobility client install error 1722. USE THESE AND NO OTHERS WITH XECUTER NAND-X. This driver pack for NAND-X includes NAND PRO v2.0d and all the Windows drivers you need (both x86 and x64). Then use the tutorial for dumping your NAND and also Flashing Xell and Freeboot.
Step by Step Instructions On How To Install Nand-X Drivers These examples show the drivers being installed on a Windows 7 machine. The process is pretty much the same on XP and Vista - both 32bit and 64 bit. Goto Windows Device Manager.
Plug in the Nand-X via USB. You will see a device called 'MemoryAccess' 2.
Right Click on 'MemoryAccess' and select 'Update Driver Software.' Select 'Browse My Computer For Driver Software' - It may say something different in XP or Vista - just choose the manual option and not the auto option. Select the folder where you unpacked the drivers that you downloaded. The example shows they are on the C drive in the nandpro_20d_drivers folder. Make sure the sub folders box is ticked. If you see this warning sign just select 'Install This Driver Software Anyway' 6.
Simple wasn't it? Once installed correctly this is how the Nand-X is listed in Device Manager.
NAND Chip Drivers NAND technology users such as USB pen drives, DOMs, Compact Flash memory, and SD/MMC cards emulate standard storage interfaces such as SCSI or IDE over NAND flash, so you don't need to develop NAND drivers to communicate with them. On-board NAND flash chips need special drivers, however, and are the topic of this section. As you learned previously in this chapter, NAND flash chips, unlike their NOR counterparts, are not connected to the CPU via data and address lines. They interface to the CPU through special electronics called a NAND flash controller that is part of many embedded processors. To read data from NAND flash, the CPU issues an appropriate read command to the NAND controller. The controller transfers data from the requested flash location to an internal RAM memory, also part of the controller. The data transfer is done in units of the flash chip's page size (for example, 2KB).

In general, the denser the flash chip, the larger is its page size. Note that the page size is different from the flash chip's block size, which is the minimum erasable flash memory unit (for example, 16KB). After the transfer operation completes, the CPU reads the requested NAND contents from the internal RAM. Writes to NAND flash are done similarly, except that the controller transfers data from the internal RAM to flash. The connection diagram of NAND flash memory on an embedded device is shown in.
Layout of a NAND flash chip. Often, the NAND controller performs error correction and detection in hardware by operating on the ECC fields in the OOB area. If your NAND controller does not support error management, however, you will need to get MTD to do that for you in software.
The MTD nand_ecc driver ( drivers/mtd/nand/nand_ecc.c) implements software ECC. Linux run background. Also shows OOB memory bytes that contain bad block markers. These markers are used to flag faulty flash blocks and are usually present in the OOB region belonging to the first page of each block. The position of the marker inside the OOB area depends on the properties of the chip.
Bad block markers are either set at the factory during manufacture, or by software when it detects wear in a block. MTD implements bad block management in drivers/mtd/nand/nand_bbt.c. The mtd_partition structure used in Listing 17.1 for the NOR flash in works for NAND memory, too. After you MTD-enable your NAND flash, you can access the constituent partitions using standard device nodes such as /dev/mtd/X and /dev/mtdblock/X. If you have a mix of NOR and NAND memories on your hardware, X can be either a NOR or a NAND partition. If you have a total of more than 32 flash partitions, accordingly change the value of MAX_MTD_DEVICES in include/linux/mtd/mtd.h. To effectively make use of NAND storage, you need to use a filesystem tuned for NAND access, such as JFFS2 or YAFFS2, in tandem with the low-level NAND driver.
