Hi,
We produced a board base on MPC8309twr development board. 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 ?
Thanks!!!
Try to see if it is software issue or hardware issue is to configure the loopback mode by setting GUMR[DIAG] = 01. If the lookback works, then issue is with hardware: pin configuration error, clock, PHY, or signal problem; if the loopback fails, it is with software configuration problem.
Check also Device Tree Structure of your BSP.
