GPIO 6410 WinCE6

Guys help me out here, I need GPIO for C#, example with source, tried
Domodom GPIO, works fine with 2440 but the apps hung with 6410.
Is the port different? The whole approach different?
Don't have the necessary knowledge to figure this out myself, tried many
things for the last few days and no luck, the LED-Test work fine but cant
find the source for it.

Thanks

Anyone ?

There isn't a lot of response here, no one have used LED or the GPIO on the
6410 ?
Any help would be appreciated, sample, Register addresses, direction of any
kind...

Thanks
