Subject: [U-Boot-Users] MII - RMII Link status detection
Date: Wed, 13 Jun 2007 15:08:24 +0200 [thread overview]
Message-ID: <466FEC48.1020802@brunel.de> (raw)
Hello,
i run u-boot on the Embedded Planet EP88xC evaluation board.
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.
Best Regards,
Ingo
