For the answer of "petermcs"
I don't understand where adjust the XMEMCODE_SIZE macro which you can define in the Project Options\defines tab, e.g. XMEMCODE_SIZE=0x60000,
When you open the Rabbit Gui you will see at the top the menu options;
FILE, EDIT, COMPILE, RUN, INSPECT, OPTIONS, WINDOW, HELP
Select OPTIONS, then select PROJECT OPTIONS, you will see several tabs like COMMUNICATIONS, COMPILER, DEBUGGER and DEFINES;
Select DEFINES in that window right where it says Global Macro Definitions: Please add XMEMCODE_SIZE=0x60000
