Same as you "(no sign of life on the serial port)"

So I guess there is a difference right off the bat here: I have
OMAPL138 evm from LogicPD, base board 1013527 rev 5; SOM 1014650 rev
A.

There's another difference -- I have tried rebuilding also but I
always gave up when 'timake' was not available. How are you working
around this? You are perhaps rebuilding in windows with CCSv3?

I'll try the 'targetType' option also.

Ok well that's promising.

I think it would be good to know how you're rebuilding the Flash and
Boot utilities and what compiler you are using for building u-boot. I
am using codesourcery's 2009q1 here.
