twr-k60n512 ethernet phy

[franticcarlitos]

Hi,

on the schematic diagram of k60n512 demo-board the jtag connector debug traces' signals are connected to the microcontroller dedicated pins. This thing is possible because the uC is interfaced in RMMI mode with the ethernet PHY.

I want to use the MII interface signals instead, but MII0_RXD2 and MII0_RXD3 share the TRACE_D0 & TRACE_D1 pins.

How can i resolve this issue?

Can you help me with any suggestions?

Thanks

Hi, Carlitos

I think you have two solution for your applicaiton. One is you can only use SWD lines: SWDIO, SWDCLK, /RESET, VDD, GND. You can also only use JTAG signals: TDI/TDO, TCK, TMS PLUS /RESET, VDD, GND. So you need not have to use trace data signal.

Hope my reply can help you.

Best Regards

Paul
