Look into archives for this mailing list, my older message date Wed, 27
Oct 2010 22:59:34 with subject 'Re: Guruplug Server Plus working to some
extent... [mge1 problem SOLVED]' has my dts where I solved just MPP
(multipurpose pin) setup problem, similar to yours I think. Look for
block MPP: mpp@10000 in there dts, maybe it could give you a hint about
setup of MPP for you.
