Hm... sounds like an oxymoron to me.
If the partition is read-only, you can only read from it, but you
cannot update it.

Maybe you could be a bit more specific? Which exact issues do you see
with using the MTD utulities?

The fundamental problem of your approach is that a read-only storage
device cannot be written (otherwise it would not be read-only). Given
the lack of precise information it is also not possible to say if the
mtd-utils are suitable for what you want to do.
Please also note that your question is quite off topic here: this has
nothing to do with ELDK. If you have specific, MTD related questions
you should ask these on the MTD mailing list instead.
