Hello,
Question I have is -- has anyone tested JFFS on powerpc platform.
I have retrieved the latest mtd code from CVS repository and
the data read back from flash is not "correct".
The platform I am running on MPC860 based board having
intel flash which mtd is able to recognize correctly.
Here are messages during the boot to indicate that cfi probe has
detected the flash.
JFFS version 1.0, (C) 1999, 2000 Axis Communications AB
physmap.c physmap flash device: size 400000 at address 28000000
cfi_probe_new_chip map->buswidth 4
Custom flash device: Found 2 x16 CFI devices at location 0 in 16 bit mode
JEDEC ID: B0 D0
The /proc/mtd shows following output which matches the partition table I
have setup.
sh-2.04# cat /proc/mtd
dev: size erasesize name
mtd0: 00400000 00020000 "Custom flash device"
mtd1: 00080000 00020000 "Bootrom Area"
mtd2: 00040000 00020000 "Custom Flash Bank #2 2x128KB"
mtd3: 00040000 00020000 "Custom Flash Bank #2 2x128KB"
mtd4: 00300000 00020000 "Custom Flash left overs from 4MB Flash"
Now I execute command and I see the following output
mount -t jffs /dev/mtdblock4 /tmp/jffs
cp /etc/inetd.conf /tmp/jffs/inetd.conf
sh-2.04# cp /etc/inetd.conf /tmp/jffs
sh-2.04# ls -l /etc/inetd.conf /tmp/jffs
-rw-r-xr-- 1 root root 2880 Jan 10 2001 /etc/inetd.conf
/tmp/jffs:
total 3
-rw-r-xr-- 1 root root 2880 Dec 31 16:05 inetd.conf
However if I try to see contents of this /tmp/jffs/inetd.conf I see
following output instead of my inetd.conf,
sh-2.04# more /tmp/jffs/inetd.conf
#
#tenioc.dT fn sihelifsed birct ses ehivre sectahtliw eb lava bali#

eeht nur gninENI p DTecor ,sstideiht if s ,elnehtnes ht d #
eENI p DTecora ssGIS PUHngis
Also now if I reboot the system and remount the device /dev/mtdblock4 I
don't see the file inetd.conf, what am I doing wrong?
