Hi,
I have been trying to get the mtd driver working with the flash
device on the TS-5300 card - all seemed to be going well :=

physmap flash device: 200000 at 9400000
Amd/Fujitsu Extended Query Table v1.1 at 0x0040
number of CFI chips: 1
cfi_cmdset_0002: Disabling fast programming due to code brokenness.
kmod: failed to exec /sbin/modprobe -s -k cmdlinepart, errno = 2

kmod: failed to exec /sbin/modprobe -s -k RedBoot, errno = 2

Using physmap partition definition
Creating 3 MTD partitions on "Physically mapped flash":
0x00000000-0x000e0000 : "BOOT FIRMWARE"
mtd: Giving out device 0 to BOOT FIRMWARE
ftl_cs: FTL header not found.
0x000e0000-0x00100000 : "BIOS-DO_NOT_TOUCH"
mtd: Giving out device 1 to BIOS-DO_NOT_TOUCH
ftl_cs: FTL header not found.
0x00100000-0x00200000 : "PNC-2000 filesystem"
mtd: Giving out device 2 to PNC-2000 filesystem
ftl_cs: FTL header not found.
# cat /proc/mtd
dev: size erasesize name
mtd0: 000e0000 00010000 "BOOT FIRMWARE"
mtd1: 00020000 00010000 "BIOS-DO_NOT_TOUCH"
mtd2: 00100000 00010000 "PNC-2000 filesystem"
But then I tryed to put the jffs2 file system image onto
the device :=
# cp /myapp/jffs2_file_sys.img /dev/mtd0
cp: unable to open `/dev/mtd0': No such device
#
but I have the device !
# ls -al /dev/mtd?

crw------- 1 root root 90, 6 Jan 1 1970 /dev/mtd3
crw------- 1 root root 90, 8 Jan 1 1970 /dev/mtd4
So Close but, So Far ;(
Can anyone suggest what I may have cocked-up ?
Where I can go from here - be nice ;)
TIA,
Frank.
