Abatron has no plans to add SPI/NAND flash. 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. Matrix Nand Flasher THESE ARE THE OFFICIAL XECUTER DRIVERS FOR NAND-X. THEY ARE COMPATIBLE WITH ALL VERSIONS OF NANDPRO INCLUDING V3. 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).
This is a very cheap alternative to the NAND X and JR Programmer, ideal if you are not looking to do multiple repair and diagnostic work, they do not come with any wires and we recommend 26-30 AWG wire. These programmers can not program diagnostic chips, however, there is a simple mod you can perform that will allow you to do so, it involves making a small breakout board with a capacitor and a couple of wires.
WHEN USING THIS PROGRAMMER WITH THE J-RUNNER SOFTWARE, IT USES THE NAND X DRIVERS AND IT WILL REPORT THAT IT HAS FAILED TO WRITE TO EVERY BLOCK WHEN YOU WRITE TO THE NAND, THIS IS FALSE AND IT WILL HAVE WRITTEN PERFECTLY, JUST IGNORE IT AND LET IT CARRY ON WITH THE PROCESS.

NAND data
Please, find here the table describingdifferent characteristics of various NAND flashes.
NAND vs. NOR
Beside the different silicon cell design, the most important difference between NAND and NOR Flash is the bus interface. NOR Flash is connected to a address / data bus direct like other memory devices as SRAM etc. NAND Flash uses a multiplexed I/O Interface with some additional control pins. NAND flash is a sequential access device appropriate for mass storage applications, while NOR flash is a random access device appropriate for code storage application. NOR Flash can be used for code storage and code execution. Code stored on NAND Flash can't be executed from there. It must be loaded into RAM memory and executed from there.
NOR | NAND | |
Interface | Bus | I/O |
Cell Size | Large | Small |
Cell Cost | High | Low |
Read Time | Fast | Slow |
Program Time single Byte | Fast | Slow |
Program Time multi Byte | Slow | Fast |
Erase Time | Slow | Fast |
Power consumption | High | Low, but requires additional RAM |
Can execute code | Yes | No, but newer chips can execute a small loader out of the first page |
Bit twiddling | nearly unrestricted | 1-3 times, also known as 'partial page program restriction' |
Bad blocks at ship time | No | Allowed |
Some facts about write speed.
NAND is typically faster than NOR for large writes. Hitfilm pro 2017 mac torrent. A typical NOR write is 10uSper word, which results in 1280uS per 512 bytes on a 32-bit bus. A typical NAND write is 50nS per byte + 10uS page seek + 200uS program which results in 236uS per 512 bytes on a 8 bit bus.

As NAND Flash is cheaper than NOR Flash and has a very slim interface it was selected as the optimum solution for large nonvolatile storage applications such as solid state file storage, digital audio/voice recorder, digital still camera and portable applications requiring non-volatility.
NAND Types
There are various types of NAND Flash available.Bare NAND chips, SmartMediaCards, DiskOnChip.
SmartMediaCards are bare NAND chips covered by thin plastic. They are very common indigital cameras and MP3 players. The card itself contains nothing smart at all. It getssmart by software.
DiskOnChip is NAND Flash with additional glue logic as a drop in replacement for NOR Flash chips. The glue logic provides direct memory access to a small address window, which contains a boot loader stub, which loads the real boot code from the NAND device. The logic contains also control registers for the static NAND chip control lines and a hardware ECC generator.
NAND technical view
The memory is arranged as an array of pages. A page consists of 256 / 512 Byte data and 8 / 16 Byte spare (out of band) area. Newer chips have 2048 Bytes data and and 64 Bytes spare area sizes. The spare area is used to store ECC (error correction code), bad block information and filesystem-dependent data.n pages build one block. The read / write access to data is on a per page basis. Erase is done on a per block basis. The commands to read / write / erase the chip is given by writing to the chip with the Command Latch Enable pin high. Address is given by writing with the Address Latch Enable pin high.
There are only a few lines necessary to access NAND Flashmemory.
16 bit buswidth chips are supported.
Pin(s) | Function |
I/O 0-7(15) | Data Inputs/Outputs |
/CE | Chip Enable |
CLE | Command Latch Enable |
ALE | Address Latch Enable |
/RE | Read Enable |
/WE | Write Enable |
/WP | Write Protect |
/SE | Spare area Enable |
R/B | Ready / Busy Output |
As it is necessary to use the spare area, the /SE (Spare area Enable) pin should be tied to GND. /CE, CLE and ALE should be GPIO pins or latched signals. It's possible to use address lines for ALE and CLE, but you have to take care about the timing restrictions of the chip !
/RE and /WE can be tied to the corresponding lines of the CPU. Make sure, that they are logicaly combined with the corresponding chipselect. You can also use two different chipselects for /RE and /WE, but be aware of data hold time constraints of your NAND chip. Data hold time after rising edge of /WE is different to data hold time after rising edge of chipselect lines!
I/O 0-7(15) are connected to the databus D0-D7(D15). The /WP pin can be used for write protection or connected to VCC to enable writes unconditionally. As NAND flash uses a command driven programming and erasing, an accidental write or erase is not likely to happen. The Ready / Busy output is not necessary for operation, but it can be tied to a GPIO or an interrupt line.
Filesystems supporting NAND
One major problem for using NAND Flash is, that you cannot write as often as you want to a page. The consecutive writes to a page, before erasing it again, are restricted to 1-3 writes, depending on the manufacturers specifications. This applies similar to the spare area. This makes it necessary for the filesystem to handle a writebuffer,which contains data, that is less than a page
At the moment there are only a few filesystems which support NAND:
- JFFS2 and YAFFS for bare NAND Flash and SmartMediaCards
- NTFL for DiskOnChip devices
- TRUEFFS from M-Systems for DiskOnChip devices
- SmartMedia DOS-FAT as defined by the SSFDC Forum
- UBIFS for bare NAND flash
JFFS2, NTFL, and UBIFS are Open Source, while TRUEFFS is a proprietary solution. SmartMedia DOS-Fat is a specification from SSFDC forum. It is somewhat open under a non disclosure agreement with Toshiba, who owns all rights on this specifications. NTFL is designed for the usage of DiskOnChip devices. JFFS2 supports raw NAND chips and SmartMediaCards at the moment. A JFFS2 support for DiskOnChip devices, based on the NAND code, is planned. There are some other Open Source projects for NAND filesystem support, but there's no other working solution than JFFS, YAFFS, and UBIFS at the moment of this writing.YAFFS is available from YAFFS-Homepage.YAFFS is faster than JFFS2 and consumes less RAM, JFFS2 provides on the fly file compression anddecompression, which is very helpful for small FLASHs. UBIFS provides compression similar to JFFS2, butis usually a better choice for large NAND flash chips (see here for more information on UBIFS, including some notes about how it compares to JFFS2).
There is currently no support for the wide spread SmartMedia DOS-FAT filesystem, mainly because it's not a reliable filesystem for industrial usage. It's ok for multimedia applications. The hardware support layer is designed to support an implementation of SmartMedia DOS-FAT. There are some efforts to implement it, but it's in an early stage. There are a couple of SmartMedia Card adaptors for USB, PCMCIA, FireWire . with Linux drivers available, which support the SmartMedia DOS-FAT.
JFFS2, YAFFS, and UBIFS include bad block management, wear leveling, error correction and providereliable filesystems for industrial use on top of NAND Flash.

HOWTO implement NAND support
Where can you get the code ?
NAND support is now present in the upstream kernel code, including JFFS2and UBIFS. The latest code is also available fromGIT and daily snapshots.
If using JFFS2, there are four layers of software:
- JFFS2: filesystem driver
- MTD: Memory Technology Devices driver
- NAND: generic NAND driver
- Hardware specific driver
The MTD driver just provides a mount point for JFFS2. The generic NAND driver provides all functions, which are necessary to identify, read, write and erase NAND Flash. The hardware dependent functions are provided by the hardware driver. They provide mainly the hardware access information andfunctions for the generic NAND driver. The same applies for YAFFS.
API Documentation
A complete API documentation is available as DocBook template in theDocumentation/DocBook directory of the MTD source tree.
Read the API documentation online
Supported chips
Most NAND chips actually available should be supported by the current code. If you have a chip, which is not supported, you can easily add it by extending the chiplist in drivers/mtd/nand/nand_ids.c. The chip name does not longer contain cryptic part numbers, as the deviceID is just an information about size, erase block size, pagesize and operating voltage.Add an entry, which contains following information:
{ name, id, pagesize, chipsize, erasesize, options }
{ name, id, pagesize, chipsize, erasesize, options }
ref | comment |
name | string: 'NAND 'size' 'voltage' 'bus-width' |
id | chip device code. This code is read during nand_scan. Check datasheet for the code of your chip |
pagesize | Page size (0,256,512). 0 indicates that the pagesize can beread out from the chip in the extended ID |
chipsize | The total size of the chip in MiB |
erasesize | the erasesize of your chip in bytes. 0 for chips with extended ID |
options | Options. Bitfield to enable chip specific options. See nand.h |
Please contact NAND driver maintainer to include it in the public source tree.
Manufacturer codes are scanned during nand_scan too. If the code is one of the known codes in the manufacturer ID table, the name of the manufacturer is printed out, else 'Unknown' is printed. This happens when your hardware driver is loaded and calls nand_scan. Add codes, which are new and contact NAND driver maintainer to include it
