All signals should be made accessible at least as testpoints that can then be fed via some

needle adaptors to the ARM standard JTAG connector. If cost and space allow, the connector

can also be directly put on the target PCB. The connector is a standard two row, 20-pin header

connector with a pitch of 0.1 inch / 2.54 mm and should have a collar to avoid incorrect

mounting.
