I don't know this board off-hand, but "special debug header" to me, =20 should just be a header, which to me, should mostly be some =20 interconnection adapter. Is there any special logic in these things =20 such that some devices cannot be debugged without it? If so, this =20 would certainly affect my choice of chips in the future. Cheers, -Neil.
