Re: [microblaze-uclinux] problems with flatfs

[Vijai S Kumar <Vijai.S.Kumar@xxxxxxxxxxxxxxxx>]

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:

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

Regards,

John
