[U-Boot-Users] PQ2FADS-VR 2nd Ethernet

[Jihua Cheng]

Yuli,

Thanks very much!

Here is the sympotoms.

Based on the PQ2FADS-VR schematic, I route parallel portC pin PC17(Clk 15 for RX) and pin PC16(Clk16 for TX) for FCC3. PortB PB4~PB17 are enabled for FCC3. When I use ping command, I got "fec: tx error!" message in the console. I found the message is from fec_send(...) at cpu/mpc8260/ether_fcc.c. It seems CPM did not send out the data to Phy. 


1) I check BCSR3. Both FETHIEN2 and FETH2_RST are 1.
2) Phy Register seems OK (Reg0 = 0x2100, reg1 = 0x7809).
3) I check PortB PB4~PB17. Dedicated Pin setting seems OK.

Where do I need to check?

I appreciate your help!

Regards,

Jihua

Upgrade to the top of CVS before you start changing anything. 1.0.0 is
too old.

First of all, "does not work" is not good problem description. Could you
explain what happens exactly? On this board, there are several more
things which can require initialisation. Check BCSR and PHY. If you
upgrade to CVS top, you'll see what's done for FCC2. To check PHY state,
you can use mii command.
