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?
Regards
Greg
