Thanks for the help from Spence. I applied patch, it's partially working. Actually I set REDUCED flag on interface, so the real problem should phy register 20. I originally I set it to 0x0ce2, the mac's speed is wrong. Thank you very much!

But it's only partially working now. I can ping out from my customized board to another PC NIC, but cannot ping from PC to my board. I noticed tsec_halt is call after calling ping, so maccfg1 is retored back to disable tx/rx, and phy is shutdown. Could this be the reason? I tried to remove tsec_halt, things become worse. Beside I can only ping one way, now it's only pingable from my board for the first time. Anyone has solution for this?

Regards,

Try the following that was submitted as a patch for u-boot but has not yet been integrated:

[DNX#2006102042000014] Add Marvell Phy and RGMII support to eTSEC setup

This sets up the eTSEC and the Marvel Phy to support 10M, 100M and 1000M rates when configured in RGMII mode.

  Hello,

  My cpu is MPC8343E with dual tsec, phy is marvell 88E1111S. Now

the physical link is up, but I just cannot ping. I printed some debug message about maccfg1/2 registers:

...

  => ping 192.168.1.1
  tsec_halt
  Trying TSEC0
  tsec_halt
  Speed: 100, full duplex
  TSEC0: maccfg2 = 0x7205
  TSEC0: maccfg1 = 0xf
  Using TSEC0 device
  tsec_halt
  ping failed; host 192.168.1.1 is not alive

  I checked the MAC transmi counter register there are packets

sending out, but no packet on the wire. The PHY is hard wired into RGMII to copper mode. Could anyone who has done similiar work point to where the problem is? Where to look at?

...
