Like the name indicates the board is equipped with a Freescale MPC885 processor. On the board are two PHYs connected over MII. With u-boot i am able to see the link status of the PHYs with a slightly modified do_mii function. My main question is, if anyone knows, if it is also possible to check the link status of the PHYs over RMII, because on our target the PHYs shall be connected over the reduced interface. My second problem has nothing to deal with u-boot but with Linux: We want to use the two network devices as one bonding device for high availability.So i configured and compiled the bonding module and the ifenslave command. Transfered it to the eval board and could successfully load (insmod) the module. The problem is that the bonding module do not receive a link down signal from the fec driver and so do not recognize a missing/broken cable or similar.
