Hi:
I have a confussion about the RMII and MII mode about the Enthernet design: I find some of the information about the RMII and MII, it says that RMII is a simpler way to implement the communication of the Enthernet, RMII just save half of the signal lines compare to the MII mode, well, does it means the RMII lines in the tms570LS3137 HDK schematics like RMII_CRS_DV, RMII_RXER is not just RMII lines, if I choose the MII mode in the promgram, ther are also serve as MII_CRS_DV and MII_RXER.Is that correct?
Besides, I noticed that you stronly recommend to add some pull up or down resistors to RXD_2 ....and some other signals, why not add them in the TMS570LS3137 HDK directly?
At last, I find you suggest that do not use the RMII mode in porduction in the TMS570LS3137 Control Card schematics, but you just design it in the RMII mode, why you suggest not use the RMII, is that unstable with the TMS570LS3137 MCU? why you design it in RMII mode?
