Now I need connect MPC8309 MII (eth1) to BCM53115 RvMII port directly. But the kernel cann't detect the PHY, and abort to initialize it. What configurations need to be set in the kernel ?<BR />Thanks!!!</P></BODY></HTML> Thu, 19 Apr 2018 00:24:55 GMT lijiankun198 2018-04-19T00:24:55Z https://community.nxp.com/t5/PowerQUICC-Processors/How-to-connect-MPC8309-MII-to-BCM53115-RvMII-port/m-p/747064#M2324 <HTML><HEAD></HEAD><BODY><P>Hi,<BR />We produced a board base on MPC8309twr development board.
