Subject: [U-Boot-Users] transmission just works in loopback mode
Date: Thu, 23 Feb 2006 19:39:01 +0100 [thread overview]
Message-ID: <20060223183901.GA2865@false> (raw)
Dear u-boot users,
i used the MPC875 FEC internal loopback mode and the external
transceiver-loopback mode. In both cases i could send *and* receive the
data.
But when using no loopback at all, but a (working) crossover cable to
connect the board to a second PC (see below), no packets get received
there. Where could the failure be ?
MPC875 <-> transceiver(LTX970) <-> RJ45-connector <-> crossover
-cable <-> second PC with RJ54-connector
my custom board contains a MPC875, whose FEC is connected to a LTX970
transceiver chip, which uses a twisted pair cable interface.
best regards
Josef
