Re: [Ltib] yaffs image creation seems to have some problem

[Stuart Hughes]

Hi Gernot,

I've never used the yaffs deployment option.  This was added by the i.mx
team.  However, they would have used this, so at least for the
combinations of the tool and kernel they had it worked.  Hopefully there
is someone out there lurking who worked on i.mx who can answer.
Alternatively, you could try contacting Freescale.

On thought is you could check your yaffs by using unyaffs (or similar)
on your host to see if the filesystem is valid.

Regards, Stuart
