Subject: [U-Boot-Users] test MPC875 FEC -> LTX970 connection with loopback mode

Dear u-boot users,

I am using a MPC875 board, on which the FEC is connected to a LTX970
transceiver chip. Connecting to LTX970 MII management interface works
correctly, but transferring data from the MPC to the LTX over the wire
doesn't work yet. 
To find out if the data flow breaks between MPC and LTX or between LTX
and the twisted pair wire, i would like to use the LTX loopback mode.
Has this done someone before ? Is there some test code included in
u-boot ?

thanks, best regards
Josef
