I am trying to develop a code for ethernet using MII interface. But looking at the schematics I saw that the MII0_RXD3 is multiplexed with JTAG's TRACE_D1 pin and MII0_RXD2 is multiplexed with JTAG's TRACE_D0 pin. I am using P&E 20 pin JTAG debugger for debugging. I need some advice with the following doubts:
1) Is there any safe way to route these pins to both ethernet and jtag?
2) In such a scenario, I won't be able to debug the code right?
3) If I use the JTAG to only load the program, then remove it and run the ethernet code, is it likely to cause any issues?
I hope I have been clear enough about my questions. If you have any ideas, please share it here.
