Using MicroZed 7020 and Vivado 2014.4.1_63036
I would like to be able to read ethernet signals from PL without disconnecting the path from ENET 0 through the GMII/RGMII Adapter and out to MIO[16:27,52,3]. I have tried re-customizing the Zynq7 PS from the block diagram by changing the MIO Configuration of ENET 0 to EMIO, but this has the effect of removing the connection to MIO. This requires that I add another PHY that connects to PL, rather than using the PHY that already exists on the MicroZed. Is it possible to sniff the ethernet signals in PL while using the current hardware?
Attached: I have highlighted red the connections in the Ethernet Controller block diagram (from UG585) that I would like to use.

Hi
No these configuration is not possible,you can use only MIO or EMIO connecting to the MAC and not both at the same time.
