Go to www.intel.com and download the datasheet on this part and see if it is a
CFI compatable NOR flash or not.

If not CFI, but is NOR, then try to use the JDEC module, rather than the CFI
module. If Not NOR (i.e. if NAND)
then I don't know.

Hope this helps.

Intel flash

[Darshak]

Hi,

I have read that INTEL has strataflash.

Is it bare NAND/nor file system?what is its basic use in Linksys?

 

What file system does it use? Can we have JFFS2 for that ?

 

What is difference in CF flash/DOC flash and this INTEL flash .?

 

 

Thanxs!

Yes.  Read their website on flash chips.

It's a type of NOR flash chip.  We have no idea what it's usage is in
Linksys.  Especially given that Linksys is a company, so it could be
used for a variety of things.

> What file system does it use? Can we have JFFS2 for that ?

Strataflash can be used with several filesystems, including JFFS2,
assuming there is an underlying device driver in MTD that can talk to
it.

> What is difference in CF flash/DOC flash and this INTEL flash .?

CF flash doesn't show up as real flash.  It shows up as an IDE device.
 Intel flash is a raw flash chip and it's up to a board designer to
determine how it is addressed.

I see you use some progressive formula for number of line brakes at the
end of each line. But I cannot figure out which one.

If number of brakes is y, while the number of line is x, we have the
following data for y(x):

y(0) = 2
y(1) = 2
y(2) = 4
y(3) = 4
y(5) = 6
y(6) = 5

What's the formula?

Hi,

I believe that the problem you are seeing is
that the device is using cmdset 0x0003, which
is close to cmdset 0x0001. Cmdset 0x0001 is 
supported by mtd so a quick and not so dirty
fix is to add the following two lines in 
cfi_probe.c, function cfi_cfi_probe(),

if(cfi.cfiq->P_ID == 3)
	cfi.fgiq->P_ID = 1;

after the two lines (around line 343)

/* Do any necessary byteswapping */
cfi.cfiq->P_ID = le16_to_cpu(cfi.cfiq->P_ID);

Hope this helps,

K.D.

Hi,all!
Has anyone experience in Intel StrataFlash Memory(28F128J3A) with ext2
or JFFS on it??

Gould show it to me!

Thanks,

I'm working Intel BootBlockFlash Memory(28F160B3) with JFFS.
but, it's in progress.
