I'm trying to understand how a JTAG connector looks. To successfully interface with a board, are there any alternatives to JTAG?
Will all the pins of the JTAG be clumped together, or can they be spread apart, like in different corners of the board?
I have a complex board I'm looking at, and it has a lot of TP (test points) on the board. Can any of them, together, form a JTAG?
Will there be any marking on the PCB to help identify JTAG?
