Hi Cliff,

	Thnaks for the suggestion. I understand the point. Righ now I just 
wanted to have a "quick" test with montavista. The advantage wich I see is 
the real-time kernel. 

What would be in your opinion the problem to use the monatvista kernel 
with all the rest which is build with crosstool. What are potential 

Best Regards
