Hi,
I'm trying to get jffs2 running on snapgear4.0.7. I have an IXP430 with Intel
Strataflash. The configuration is very similar to the montajade board and
IXPDG425, but with IXP430. I fixed now to run the snapgear4.0.7 with this
hardware, but the only thing is the jffs filesystem. I have:
# cat /proc/mtd
dev: size erasesize name
mtd0: 00080000 00020000 "RedBoot"
mtd1: 00c80000 00020000 "Image"
mtd2: 00300000 00020000 "zImage"
mtd3: 00980000 00020000 "ramdisk"
mtd4: 002c0000 00020000 "s600"
mtd5: 00001000 00020000 "RedBoot config"
mtd6: 00020000 00020000 "FIS directory"
"s600" is my config fs, which I want to mount on /etc/config with jffs2.
I do:
# eraseall /dev/flash/config
Erased 2816 Kibyte @ 0 -- 100% complete.
# mount -t jffs2 /dev/flash/configblock /etc/config
I get this messages...
--snipp
Further such events for this erase block will not be printed

I already goggled a lot of this issue, but don't solved it.
What I can say, it that I also have a image with snapgear3.4 and this IXP430
and there I get everything running. But I cant this version, because there are
also a few other things in SG3.4 what are not ready for this IXP430..
But in anycase, if I first start the image with SG3.4 on this hardware, I'm
able to mount the /etc/config and read/write. When I then start the image with
SG4.0.7 I can also read/write. So I guess it couldn't be the hardware, it must
be something in the changes of jffs2 from SG3.4 to SG4.0.7.
Does anyone has an idea?
That is going from a 2.6.17 kernel to a 2.6.26. And a diff of the
fs/jffs2 in each is kinda large.
What type of flash is this board using? From the erase sizes I am guessing
some type of intel strata flash? Is it a J3 or P30 type?
I use the Intel Strata Flash JS28F128 J3F75.
Ok, you don't have to deal with the power up locked segments then.
The "0x0080" read value sure looks like the read status result of
the flash, and not the contents of that addressed location.
If you dump the contents of the flash what does it look like after
the erase. Something like with:
hexdump /dev/flash/config
