Re: [microblaze-uclinux] how to mount flash via jffs2 as dir /mnt ?

Hi Falk,

Something else occurred to me about your setup - see below:

I don't think it will work if you try to get MTD to manage only a small
region of your flash.  It will want to control entire chip.  For this
reason, I suggest you use a full MTD partition that covers the entire
chip, but perhaps only create /dev nodes that correspond to the region
you are interested in.

Regards,

John
