Thanks for the response Krzysztof, >Hi, > >"Mo, Vincent" <vincent.mo@xxxxxxxxxxxxxxxxxx> writes: > >> The problem I'm experiencing with using the 2.6.28.1 kernel is this. >> I've been able to build it and load it onto my IXDP465 development board >> and have verified that the Ethernet works. > >Good to know.

Yes I am, I'm using the exact same sources and config. >MDIO doesn't use the firmware, it's connected directly to the pins >(balls actually). Even though MDIO doesn't use the firmware, the NPE needs it right?

This is strange, the phy is clearly receiving packets and is toggling its' link/activity line, but it's not able to transmit the received packets to the CPU because there is no receive clock. ------------------------------------------------------------------- List admin: http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm FAQ: http://www.arm.linux.org.uk/mailinglists/faq.php Etiquette: http://www.arm.linux.org.uk/mailinglists/etiquette.php
