I claim to be using 1.3.2-rc2 but my repository clone could be introducing problems. I'll do a clean clone and rebuild of u-boot, hopefully that is all it is. It is connection is through a commercial switch, should be 100bT full duplex (not verified, cannot see the blinky lights from here). I don't know the board rev off-hand (I'm not on-site at the moment). => version U-Boot 1.3.2-rc2-g330a77f6-dirty (Feb 25 2008 - 22:21:12) MPC83XX root:~> cat /proc/cpuinfo processor : 0 cpu : e300c1 clock : 528.000000MHz revision : 2.0 (pvr 8083 0020) bogomips : 131.58 timebase : 66000000 platform : MPC836x MDS Thanks, gvb
