How to passby the PRU to implement EtherCAT MASTER on ICE?

Hello all,

I am a very start player on sitara AM335x, in my hands I have a ICE board and already play with some demo bios projects and Ethercat Slave demos.

Now I am starting to build a EtherCAT Master solution on this board.From some of the page in the BBS, I got to know it is not need to use PRUSS for EC Master solution.But the phy chip on the ICE board (TK110) is directly connected to the PRU Pins, So could some one help to tell me how to passby the PRU when the data package is coming to the ICE board and  sending from the ICE to slaves?

Thanks in advance!
