Re: [microblaze-uclinux] problems with flatfs

Hello together,

thanks for your hints, but I've got a closer specified problem to solve now:
when booting, uclinux should print the following lines on minicom:

....
microblaze auto-config flash probe(0x21000000,8388608,2): 800000 at 21000000
amd/fujitsu extended query table v1.0 at 0x0041
flash: ....
flash: ....
number of cfi chips: 1

what I get instead is:

....
microblaze auto-config flash probe(0x21000000,8388608,4): 800000 at 21000000
cfi: found no flash device at location zero
....
can you tell me where i can change the 'four' at the end of the brackets to a 'two' ? 

thanks,

sigi

hi john
i think the partition is ok in this case.
but i think mr. sigi and others forgot to enabled the "direct char device access support" in kernel config. 
so if u want to use flatfsd than u can try with this feature enabled.
i think it will be ok.

thanx

Hi Sigi,

flatfsd expects there to be a writeable flash partition on
/dev/flash/config.  All of the standard mb-uclinux MTD flash maps
(drivers/mtd/maps/mb_auto.c for example) create such a partition.

The message you are seeing "failed to write flatfs, no such device" says
that you don't have a flash partition in place.

If you don't want to use flatfsd, simply disable it in the user/vendor
-> misc applications menuconfig.

There's a great intro to flatfsd on ucdot.org, let me try to find
it...ah, there is is:
http://www.ucdot.org/article.pl?sid=04/01/18/2312200&mode=thread <http://www.ucdot.org/article.pl?sid=04/01/18/2312200&mode=thread> 

This also links to an article by Greg Ungerer about flash usage in
uClinux generally - well worth a read.

Regards,

John
