noIce question

Hi all,

I’m just testing the noIce debugger/programmer and have a question.

I can compile my “hello world” (LED toggle) just fine using gcc-arm. I can also burn this file using openocd just fine.

Life is good.

Now, I would like to debug my file, and when I load noice and load the “bin” file, it’ll show the asm, but not the source…

any correct ways to debug this? Should I not be using the bin file? Now thinking about it, I’ll look at my make file and see if I need to add some debug flags?..

BTW, my compile setting are

CFLAGS = -I./ -c -fno-common -O0 -g

AFLAGS = -ahls -mapcs-32 -o crt.o

LFLAGS = -Map main.map -Tdemo_at91sam7_blink_flash.cmd

CPFLAGS = --output-target=binary

ODFLAGS = -x --syms

Hi

I havn’t used noice, but the “elf” file contains all the debug information. The “bin” file contains just the binary, machine code. So try to load the “elf” into the debugger.

I use NoICE, and Magnus is, of course, correct. You must use the ELF file to get debugging information for the debugger. There is a small complication concerning NoICE though. The NoICE GUI does not have native support for the ELF file format. You need to pre-process the ELF file with the ELFNOI.EXE program that comes with NoICE. In my setup, I have incorporated that step into my build process, so I had almost forgot about that necessary step.
