[Barrelfish-users] barrelfish on scc, how to ping the cores

[Simon Peter]

Hi Zhuwangbin,

The performance meter widget isn't supported by Barrelfish. It seems the 
system came up just fine. You might want to make sure the driver is 
actually speaking to eMAC a. Is the printed MAC address the one you 
would expect?
