    Was the EBB working correctly before you reprogrammed it?

    So, it is likely to be a hardware issue, not a software issue?

    Did the programming appear to work correctly?  If so, it may indicate that the processor is working.

    At this point, it still seems like it needs to be a hardware issue.  We've used the standard firmware to program many of these boards, and never had any problems with it.
