Beagleboard xM just arrived but one pin in JTAG missing..


I'm newbie and just received the xM, and noticed one pin from the JTAG
is missing. After some searching on the internet I came across some
high res photos of the same missing pin. So I wondered mine is ok cuz
it is by design.

Searched the PDF manual but cannot find any mention of this. Could
anyone please educate me on this? Thanks in advance.

Max, Gerald,

Thank you!
