Hello,
I used other two (we bough three XAUI-Riser-B Cards at all) XAUI-Riser-B Cards. They could ping success in u-boot. So we guess the first card is bad.
However there are still some problem when using the other two cards.
These two cards will report some initialization errors, following are the picture.

And, in u-boot, we could not use RJ45 port to success ping other PC(another port is doing well in u-boot ).
So I suspect that the u-boot and Linux version of P4080DS is not match with XAUI-Riser-B Cards. Please tell me the right version of u-boot and Linux to match with XAUI-Riser-B Cards. Following are the current version of u-boot and linux.


Thanks!
