Hi Shaun, Sorry for not mailing you but I have being tied up a bit for the last couple of days. You were right with the need for the .global directive in my .s file but I also needed to define the symbol as being an extern in my C file. Thanks for all the help, Dave >Yeah, I'll show you how to troubleshoot it too. Try running > $ arm-elf-as start.s > $ arm-elf-nm start.o >This will give you a list of symbols in start.o. You should see >something like > 00000000 t IRQVector >This says start.o provides the symbol IRQVector. >Then try > $ arm-elf-gcc -c main.c > $ arm-elf-nm main.o > 00000000 T IRQHandler > U IRQVector >This says main.o provides IRQHandler and needs IRQVector. I think you'll >probably find IRQVector isn't defined in start.o. Assembler symbols >default to the equivalent of a C static symbol.
