Does anyone know where I can get a detailed connections diagram for the Rpi, one that includes the Jtag connections.
Hi Omar,
The schematic is here: http://www.raspberrypi.org/wp-content/uploads/2012/04/Raspberry-Pi-Schematics-R1.0.pdf
A later rev is here: http://www.raspberrypi.org/wp-content/uploads/2012/10/Raspberry-Pi-R2.0-Schematics-Issue2.2_027.pdf
There may be more iterations in the upload cache if you're looking for a specific revision.
JTAG pins are on P2, on sheet 4.
HTH, or are you looking for guidance on connecting a JTAG hardware debugging probe? If so, there is some discussion of that here:
