Hi all, I'm trying to port my version of linuxppc-2.4 from 8540 to 8541. The point I'm stuck at right now is the FCC that replaces the FEC.
I checked port configuration and clock routing registers in cpm2_io/fcc_enet.c again and again, but all I get in and out is ones. The packet sizes I receive look reasonable, but the buffers are filled only with 0xff. The same goes for sending, the contents of the buffers are OK (dhcp discover...), but when capturing the output on the other side with ethereal, the packet is again all 0xff. We just discovered that apparently preamble, frame delimiter and FCS go out over the MII (at least TxD[0:3] change state), so I don't suspect a hardware bug. Any ideas? -- Stefan Nickl Kontron Modular Computers
