I would like to discuss, or even get a review of my designed small adapter board. The concept is simply: get a board with connectors, which is completely the reverse of the official XA-SK-XTAG2 board, and it can be connected between two boards. In example: Square (j8 on XP-SKC-L2) connector of the master board, and XSYS on xCORE-200 MC Audio board as a slave board.
Before I send it to a pcb mfg, I would like to take a look again, and of course get some feedback regarding of my mistakes, or any further ideas... The main goal, to have possibility to create an xn file and project for a system which have (in my scenario) two XP-SKC-L2 boards and one MC audio board connected. On this adapter board the JTAG, XLink will be used by default, debug uart and the rest of the pins will be routed to a pin. Because the square connector has 2x8 other pins too, I decided to use CMOD/PMOD kind of pinout. These are completely optional connectors here.
Problem, without an adapter board: Because of the official XP-SKC-L2 board's JTAG output nets (in case of two boards are daizy chained) has no fan outs on pins, I am not able to connect the MC Audio board to there in obvious way (ie with jumper wires). So the only position is the slice connector where jtag nets can be found.
Please see the attached pictures.Thanks!
