 		 #166012 - Broken Boards?
Responding to: Rob Stoffels's previous message
Andy Neil said:
Are you able to load programs correctly that don't use "external ram features" ?


Rob Stoffels said:
no i'm have not

So it sounds like this whole port and XDATA thing is a red herring.
It sounds like there is something fundamentally wrong with downloading to this chip.

These development boards do have been lying around for 5+ years without use, is there a chance they are broken?

Of course there's a chance - and the evidence so far suggests that it is a strong likelihood!

I guess you could spend some time testing and investigating these boards, but I think you have a better plan...

Just one thing: be kind to any other poor soul who might find these boards in the future (possibly even you), and clearly mark them as "SUSPECT"...
