Problems with DOC Millenium Plus

Problems with DOC Millenium Plus

[Roy Lauer]

Hi All,
 
We used to have DOC 2000. 
Recently, M-sys stopped manufacturing the DOC 2000, so
we bought DOC Millennium Plus instead.
 
I updated the mtd driver to the latest version from
the CVS.
 
The first problem I encountered was that the kernel
build failed due to unresolved symbol BUG_ON in
mtd_core.c and mtd_blkdevs_24.c.
I guess this is a bug.
 
Anyway, I commented out these lines and was able to
build the kernel.
 
I formatted the DOC with DFORMAT version 5.1.4 from
M-sys.
 
When I boot with the new kernel, it recognizes the DOC
correctly but complains "Could not find valid boot
record":
 
Feb  2 09:46:12 192 kernel: NFTL driver: nftlcore.c
$Revision: 1.94 $, nftlmount.c $Revision: 1.34 $
Feb  2 09:46:12 192 kernel: Using configured
DiskOnChip probe address 0xf0400000
Feb  2 09:46:12 192 kernel: DiskOnChip Millennium Plus
found at address 0xF04000 00
Feb  2 09:46:12 192 kernel: Flash chip found:
Manufacturer ID: 98, Chip ID: 75 (Toshiba:NAND 32MiB
3,3V)
Feb  2 09:46:12 192 kernel: Flash chip found:
Manufacturer ID: 98, Chip ID: 75 (Toshiba:NAND 32MiB
3,3V)
Feb  2 09:46:12 192 kernel: 2 flash chips found. Total
DiskOnChip size: 64 MiB
Feb  2 09:46:12 192 kernel: Could not find valid boot
record
Feb  2 09:46:12 192 kernel: NFTL: could not mount
device
 
The readme file advices to use nftl_format in such a
case, but this tool seems not to be available any
more.
 
I tried it with another DOC and got the same message.
 
Can anyone help me please with this situation.
What have I done wrong?
What shell I do now?
 
Roy

Probably not. There is no Linux kernel which it makes sense to use but
which does not contain the definition of BUG_ON. You're probably using a
kernel which is too old. Although there does exist a possibility that I
just forgot to include the correct header file -- I doubt it though or
someone would have complained sooner.

The DiskOnChip Millennium Plus uses INFTL not NFTL. You should be very
careful using the current INFTL code -- it does not observe the Bad
Block Table.

OK, I switched to INFTL and now I get the following:

INFTL: inftlcore.c $Revision: 1.14 $, inftlmount.c
$Revision: 1.12 $

What does it mean?
