I have installed IAR EWARM 3.40, which should have support for 
Macraigor RAVEN JTAG. When I lauch C-SPY debugger with the JTAG setup 
configured, the code downloads correctly and when the application 
starts it jump to the main function. The problem is, when I go step 
by step with the debugger, I get an error ("macraigor driver error") 
saying that only to breakpoints can be set in ROM. Could anybody 
explain me how to download the code in RAM instead of ROM (perhaps 
with a linker file example) or what to in order to put several 
breakpoints in my code with the IAR IDE?

Thank you very much. Regards,
