nftl_format

[Marc Karasek]

I just d/l and compiled the format utility to format a 32mb doc device.  

When I tried to run it, it complained about the erase size not being 8K in
size. I did a printf 
to see what size it was reading and it is 16K (0x4000).  Is this an issue
just with nftl_format?  If so i will fix this, if this is also an issue with
the driver I can look into this also.

nftl_format

[Chris Ellec]

I got an older Diskonchip with NFTL all messed up after trying to 
install Grub on it, so I had to nftl_format it.

First I had to make the changes below to get nftldump and nftl_format to 
compile again.

When I ran nftl_format, it took about 20 minutes for a 96MB DOC, is that 
normal ?

The nftl_format worked and the DOC is now back to its original state.

Chris.

Please note that the following breaks the compilation of the kernel, so 
you can only do it to compile  nftl_format then you have to change it 
back if you need to recompile bzImage.

nftl_format

Hi,

Attached is a patch to get nftl_format compiling with the latest version of
mtd. I managed to get 2 of my DoC chips into a state where DFORMAT would not
want to reprogram them. The trigger for this seemed to be loading the
grub_firmware into them with doc_loadbios. Anyway with this patch I was able
to build nftl_format and reformat both of the chips.

Regards,
Denis.
