[coldfire-gnu-discuss] Using GDB with Coldfire M52233DEMO ev-board..

[Mats Blide]

Thank you guys that's realy what I wanted to know :-).

If I want to have a GUI to GDB, is there any that would work. I have tried 
Zylin CDT plugin to Eclips but it didn't work or rather gives me the same 
problem as I explaind earlier. And after this discussion I realise that it 
my not be able to handle the board I'am using.

Rgds,
Mats
