RE: Elan SC520 - problem with MTD



Looks like I took the wrong week to go on vacation.

Could everyone who is currently doing work with either
the AMD Elan Sc520 Customer Development Platform or the
AMD Elan Net520 Demonstration Board please send me an
email and tell me what they're doing with it and what
kind of support they need from AMD?  I'll be glad to
provide whatever help/co-ordination I can.

And I'm working on getting that stupid license .pdf
removed from the tarball.  Sorry about that.
