Fujitsu MBM29LV160

We try to port Linux kernel to our embedded system that has Fujitsu's
NOR type Flash memory MBM29LV160.
If it is possible, we want to use MTD for our system. 
Does anyone let me know MTD support it or not?
Also wellcome any suggestions.

Best Regards.

MTD-CVS

May I suggest opening a new mailing list named mtd-cvs (or mtd-dev)
for CVS reports.  It seems like the CVS reports are starting to crowd
the mailing list, and most of the time I just file them away.  I think 
it would be ehlpful to everyone if the CVS messages would be put in a
separate mailing list.

FYI.

problem with modprobe and other questions

I successfully compiles mtd with the sources but i can not use modprobe
to load the modules. I did not apply the put_module_symbol... patch.
Should I also apply it? I can only use insmod.

I am using linux 2.2.16 and configured all of mtd as modules.

What parameters should I give to mknod to access mtd as a char device
and block device?

Would jffs also require a dev node? an

problems using mtd and doc2000

I have successfully compiled the mtd drivers as modules but it wont load
with modprobe only insmod. I used the latest CVS snapshot and linux
2.2.16.

What device major no should i use for /dev/mtd0?

I cant do anything because my /dev/mtd0 is not workin. How should I get
it to work? Is loading mtdcore enough?

When I try to use DOC_loadbios it only says "Open flash device : No such
device".

Definitely. I tried to do without it, but it was easier to use it.

Run the MAKEDEV script in the util directory.

Done. It's called mtd-cvs rather than mtd-dev because I'd prefer to keep 
all discussion on the MTD list.

Re: MTD CVS update: 'mtd/kernel cfi_probe.c'


er... now I've also changed the CVS notification to point at the new list 
too - which perhaps would have been appropriate in the first place :)

Is it CFI-compliant?

If so, it'll be at least detected by the current code. 

If it is capable of using the Intel command set, then it is supported. 
Otherwise, you will have a little bit of work to do to add support for it. 

It should be quite simple to add support for it if it doesn't support the 
Intel command set.

First you need to provide a 'map' driver which allows access to the flash 
chips. Look at something simple like nora.c for an example - if your flash 
chips are mapped into virtual memory then all you need to do is change a 
couple of defines in nora.c to drive your own board.

Then load the cfi_probe module and the nora module (or your own map driver).

Show me all the output you get from it.
