Hi David,
I have added following lines in the docprobe.c
static unsigned long __initdata doc_locations[] = {
--
--
#elif defined (__arm__)
0x18000000,
#else
#warning ---
#endif
0};
So i think I dont need to define it in
CONFIG_MTD_DOCPROBE_ADDRESS.
And My log message is like this .
DiskOnChip Millennium found at address 0x18000000
Flash chip found: Manufacturer ID: 98, Chip ID: E6
(Toshiba TC58V64AFT/DC)
1 flash chips found. Total DiskOnChip size: 8 MiB
out-of-line wait
_DoC_WaitReady called for out-of-line wait
.
. _DoC_WaitReady called for out-of-line wait
Could not find valid boot record
Could not mount NFTL device
In Our board SA_A1 ->DOC_A0 ..... SA_A13->DOC_A12 ,So
there is <<1 .
I have changed the ReadDOC_ and WriteDOC_
in include/linux/mtd/doc2000.h
#define ReadDOC_(adr,reg) readb(((unsigned
long)adr)+((reg(<<1));
#define WriteDOC_(d,adr,reg) writeb(d,((unsigned
long)adr)+((reg(<<1));
I am able to read & write to /dev/mtd0 using dd.
I have added nftl support. So i need to support make a
filesystem on disk on chip How can I do that.
Best Regards
Sanal.

Might have been useful had you included this information in your first
message. The HOWTO should suffice to get you going from that point.

Hi David ,
Sorry for not explaining the problem in detail.
I have read the howto's on the infradead .
But still I dont understand how to create a partition
on Disk on chip
and have filesystem on it.
I have tried with nftl_* .But I could not do anything.
Could you please explain what I need to do for making
the filesystem on DOC.
Boot Messages

. _DoC_WaitReady called for out-of-line wait
Could not find valid boot record
Could not mount NFTL device
and using nftl_format I tried to format the diskon
chip But I get an error like the following
NFTL_open
ENODEV: thisNFTL = 0, minor = 23808, ip = c94ac4c0, fp
= c965caa0
NFTL_open
ENODEV: thisNFTL = 0, minor = 23809, ip = c94ac6e0, fp

dd if=XXXX of=/dev/mtd0
I am adding part of my .config here.

Show me the command line you used. Compare it with the command line in the
HOWTO.
