I'm still struggling with my mpc8315e board , customized with a DP83848
PHY chip.
after u-boot bootup , the LED of PHY link status is blinking,
When I use ping PC FORM u-boot , it's OK.
But when I ping u-boot FROM PC , it doesn't work and I just got timeout
error etc.
I think the physical connection is OK, what could be the possible reason
for this?
Hope someone can help me out. Thanks!

What are you expecting ? U-Boot is not an OS, and there is no thread in
background answering requests from network. Except if netconsole is
used, network and the related drivers are not active when not used, I
mean when for example tftp or ping are not running.
If you want to have the network stack running, you should boot Linux.
Best regards,

Thanks, good news for me :)
It confused me because of unfamiliar with u-boot structure.
I will continue to tftp test then.
