Peripheral uart is not connected to JP1 on the tag board. Most sample applications configure P32 and P33 as the puart lines, so you have to solder wires or a connector to TP55 and TP56.
The next revision of the tag board will have headers to which you can connect jump wires and it will also use an FTDI 2232 chip so both uarts show up as virtual com ports on your PC.
You mentioned TP55 and TP56. I don't see these in the board layout document. I see P32 and P33 (which is shared with P8). Are these the points you are referring to ?
Thanks a bunch
Yes, P32 and P33.
