Re: [jornada] [newbie] 560 series

That's excellent news that you'll be able to spend some more time on it. :-)

Can I read into that, that the code for the 56x (with the uda1341)
will be pretty much the same as that for the 720? IOW, can I assume
that the 56x does indeed have the SA-1111 companion chip?

I would be very willing to help. I just need OE to fetch and patch
everything without a problem.

Would I use "0.8.4" as the version to get your latest code?

Michael.
