uClinux Ethenet on DE2-115

Hi guys, 

I am using the quartus example project DE2_115_WEB_SERVER_RGMII_ENET0 and it programs into the board and i can see the two LEDs light up on the board(DUP and 1000), i can also boot up uClinux to this which all works well. 

 

 

The board uses marvel 88e1111 chip which i enabled drivers for in the make menuconfig and also checked the altera triple speed ethernet(SLS), I am using kernel 2.6.30 

 

This seems to find the PHY fine..console output below 

found PHY with id 0x1410cc2 at address 0x10 

altera TSE MII bus: MDIO bus registered 

Altera triple speed MAC IP driver(v8.0) developed by SLS, August 2008, --linux 2.6.27-rc3 

 

When the kernel boots up and i try to do ifconfig i get the following error.  

error: no inet socket available: address family not supported by protocol. 

 

Any help greatly appreciated.

It looks like you may have left out IP support when you compiled the kernel, even though you got the driver itself in there. Look in networking at menuconfig.

can you change the DE2_115_WEB_SERVER_MII_ENET0 for mii mode for a test? remember to change the JP1 for Mii MODE.
