How do I connect a third-party cable to debug PowerPC 440 on the ML507 development board?
解决方案
A third-party cable can be connected on the BDM port (CPU JTAG Header J12) of the ML507. In order to do so, the PowerPC 440 JTAG signals must be routed to these pins. Hence, the jtag_ppc_cntlr must be disconnected.
