Connect to 7I80 was created by nhanpham
Hi all,

I'm trying to connect to the mesa 7i80 board. But it can't.
I can ping mesa Ip's "10.10.10.10" but I can't connect when I used mesaflash.

My mesa 7i80 has connected to raspberry ok. I'm trying to change raspberry to another computer to increase productivity.
mwork@debian:~$ ping 10.10.10.10

On the RPi I think you need to set the address to 10.10.10.5/24. I'm out of town but another guy on the IRC that has a 7i80 seemed to recall that. I can't check until I get home.
