evaluation kit mac address wrong

Hello  

 

I'm trying to connect the evaluation kit to the internet, but  

it is not able to get an IP address by dhcp  

looking at the packet it look lik it has a wrong mac address  

ff:ff:ff:ff:ff:ff  

 

did I miss something in the installation?

This is a broadast address. Are you sure it isn't the destination MAC in the dhcp request address? 

Which evaluation kit do you have?

This is a Nios Embedded Evaluation Kit Cyclone III edition 

 

and I was looking at the dhcp server log, so this is really the source MAC 

 

once it was 07:ff:ff:ff:ff:ff, see the log line below 

daemon.log.0:Mar 17 16:43:04 obsfrog dhcpd: DHCPDISCOVER from 07:ff:ff:ff:ff:ff via eth0: unknown client 

 

then it was ff:ff:ff:ff:ff:ff ????? 

daemon.log.0:Mar 17 16:46:57 obsfrog dhcpd: DHCPDISCOVER from ff:ff:ff:ff:ff:ff via eth0: unknown client 

 

we expected it to be something like 

00:07:ed..... (altera device) on board near RJ45

You can try and erase the last page of the flash, and then the Nios application should ask you to type the board's serial number to generate a new Mac. 

This will only work if you are using an example software with network_utilities.c
