[Barrelfish-users] [Barrelfish] Boot barrelfish on the SCC board

[Simon Peter]

Hi Jehun,

Have you tried simply executing 'make scc' after you've compiled 
Barrelfish? This should execute the right sequence of commands, 
including generation of bigimage.dat and barrelfish0.obj.

The barrelfish0.obj file referred to by barrelfish48.mt is the 32.obj 
file that is to be loaded directly into SCC RAM. It contains a small 
bootloader, the Barrelfish kernel and all user-space application 
programs referred to in menu.lst.scc.

Hope this helps,
Simon
