I don't think it is getting that far. :(

08000000 A RamBase
08000000 T _init

I can't even set a breakpoint at _init.  So I think the
RAM addresses must not be right.    And it looks from
the link you passed that they also used a timer and
ethernet.

Hopefully Jukka will pipe up shortly. 

Thanks.
