Hi, I am doing a Linux 2.6.11.11 port for a CPCI board with a 440GX processor on it. Previously, I had successfully ported 2.6.11.11 to the board's predecessor running on a 440GP processor. Due to limitations in this version of the PCB, EMAC ports 2 and 3 are not connected. The standalone kernel comes up and gets into a BusyBox shell. When I try to ifconfig the eth0 interface, the messages "eth0: Link is Up" and "eth0: Speed: 100, Full duplex." are displayed and then the target hangs. I used the OCOTEA port as a pattern for my 440GP->440GX conversion. The PHYs which are connected to EMAC ports 0 and 1 are the same PHYs as on the 440GP board (running in RMII mode). I have tried to use the function "ocp_remove_one_device" to whack EMAC2 and EMAC3. I am pretty sure that the removal worked as I no longer see init messages for those EMACs (previously I saw all four devices get initialized). The MAL reports that it has "Initialized, 4 tx channels, 4 rx channels." I used the function "ibm440gx_set_eth_grp" to force the Ethernets to both group 0 and group 1 configurations. So far, nothing has worked. Can anyone think of anything obvious that I am missing? I know that the Ethernet ports are functional as I used TFTP with our ROM monitor package to download the zImage file.
Thanks, Scott ___________________________________________________________________ Scott N.
