There was also some other dependency problems (CRC32, PROC_FS).  One of 
them is not correct in linux-2.6.6 (JFFS_PROC_FS) but the script 
"patchin.sh" now fixes it, too.

Thanks for your mail.

Use the DOS tools if you can. Or look on SnapGear's web site to see if
you can find an 'inftl_format' tool.

DOC Mill Plus 32M What next?


Hello all,

  On my arm core board there is a DOC Plus 32M.  When I use the DOC2001Plus
driver I can probe the chip "docprobe".  The chip is reported in the proc
file system.
# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00020000 00010000 "BootLoader"
mtd1: 00040000 00010000 "Params"
mtd2: 00200000 00010000 "Kernel"
mtd3: 001a0000 00010000 "Flash0 FileSys"
mtd4: 02000000 00008000 "DiskOnChip Millennium Plus"

What tools can I use on the chip to prepare it for use??  Nftl_format
reports wrong erase size of 0x10000?  I have read others postings and I am
not sure if I should be using nftl_format anyway?  Can soemone please tell
me the proper procedure to prep the chip for a jffs2 file system???

Thanks for the help!
John

I keep an nftl_format in the uClinux-dist code base that is capable
of formating INFTL as well.

Get the whole package and use uClinux-dist/user/mtd-utils/nftl_format.c

http://www.uclinux.org/pub/uClinux/dist/

Or just pull it from CVS at:

http://cvs.uclinux.org/cgi-bin/cvsweb/uClinux-dist/user/mtd-utils/nftl_format.c

It doesn't currently support erase sizes of 0x10000 either though...

Regards
Greg

mtd and 2.6.5_linuxppc (mvista) kernel does not boot

I patched the 2.6.5_linuxppc kernel from mvista linuxppc-2.5 tree with the 
current jffs2/mtd code and built an image with the mkfs.jffs2 from utils.
mkfs.jffs2 options i used:
mkfs.jffs2 -b -e 131072 -p -o jffs2.img -r cdkflash/jffs2/

I built a cramfs (kernel) + jffs2 (root) image. Here is the partition table:
0x00000000-0x00120000 : "DreamBOX cramfs"
0x00120000-0x007c0000 : "DreamBOX jffs2"
0x007c0000-0x00800000 : "DreamBOX OpenBIOS"
0x00000000-0x007c0000 : "DreamBOX (w/o bootloader)"
0x00000000-0x00800000 : "DreamBOX (w/ bootloader)"

Partition size and offset in the flash is ok, as it works with jffs2 from 
2.6.5_linuxppc kernel.

Kernel compiled with following jffs2 configuration:
CONFIG_JFFS2_FS=y
CONFIG_JFFS2_FS_DEBUG=0
# CONFIG_JFFS2_FS_NAND is not set
CONFIG_JFFS2_ZLIB=y
CONFIG_JFFS2_RTIME=y
# CONFIG_JFFS2_RUBIN is not set
# CONFIG_JFFS2_LZO is not set
# CONFIG_JFFS2_LZARI is not set
# CONFIG_JFFS2_CMODE_NONE is not set
CONFIG_JFFS2_CMODE_PRIORITY=y
# CONFIG_JFFS2_CMODE_SIZE is not set
CONFIG_JFFS2_PROC=y

My problem is now, that the image does not boot with newer jffs2/mtd patch.

INFTL_FORNAT ???

Does anyone have a copy of inftl_format?  I can't locate a copy and need it
to format my DOC Mil Plus 32.  If anyone could please tell me where to find
it.  I have looked on the Snapgear site and have not been able to locate it.

Thanks,
John

If it isn't where Greg said it was 2 hours ago then I don't know where
it is.

It should be including mtd/nftl-user.h not linux/nftl.h

The header nftl-user.h doesn't exist in neither
linux-2.6.6 and in the version of mtd-utils
imported in uClinux-dist (a rather old version,
I shall admit).

If nftl.h isn't supposed to be included from user-space,
the "#ifdef __KERNEL__ ... #endif" it contains is
useless.

I may change mtd-utils locally, but I think this
fix should also go into the kernel "just in case".
