I am however having a more difficult time getting the linux kernel=20 (linuxppc=5F2=5F4=5Fdevel from Denx) to work with PCF8563. I get error=

rtc=5Frd( ), but I can't understand why. I have compared the i2c clock signals between=20=20 It works fine on the PM520... =20
Thanks for your hints. I tried configuring the kernel for the pm520 board (make PM520=5Fconfig) and then the RTC stuff works on my board. Obviously I had something misconfigured that resulted in the strange behaviour of i2c.

eth0: status: link up, 100 Mbps Half Duplex.^^^^^^^^^^^^ Is this correct?
No, it is actually incorrect and this is something that I need to fix. My board (NS4) has a DP83847 PHY on the FEC. I modified fec.c to avoid kernel panic, but I do not have the PHY handling 100% correct yet. Ethernet communications are working though, at least when connected to=20 a Cisco Catalyst 2950 with autonegotiation it establishes 100 Mbps Full=20 Duplex. When connected to an old HP 10Mbps hub linux reports as above, 100 MBps=20 Half Duplex, but the communications do work despite wrong reported speed. Any suggestions for reference code for DP83847 with MPC5200 ? Many thanks, J=F3n Benediktsson Marel hf.
