Hi,

Im using the same board with the same IP with uClinux but can&#39;t seem to get it working. I dont understand how the marvell chip has an 8bit rx/tx bus but the opencore ethernet MAC IP has only 4 bits rx/tx?

When i start uClinux up and type &#39;ifconfig eth0 up" one of the messages it gives me is jabber... which I think is related to too many packets? Ive tried to connect the system as you have done in your screen shots (I hope thats ok). What did you do with the remaining erxd pins?[/b]

I simply connected the remaining etxd pins "etxd[7..4]" to the ground :rolleyes:

Concerning the 8-bits / 4-bits problem, you should take a look on this two pages :
