I was pleased to find that it was possible to set up Eclipse Galileo CDT to debug ARM code running under emulation; in this case, DS targeted homebrew built with the GCC ARM toolchain, via devkitPro, running inside of DeSmuME, on Ubuntu 9.04.
You make new a debug configuration and
- under “Main” tab, set the executable to your ARM9 ELF binary (.elf file);
- under “Debugger” tab, set the debugger to “gdbserver”;
- point the debugger path to where your arm-eabi-gdb lives;
- set the connection to use TCP from localhost at, say, port 10000.
Then, for convenience, make an external program entry for desmume with arguments
Run desmume first, then Debug in Eclipse, and you will be paused in the first line of source.
Until this point I was using Insight targeted for arm-eabi to do debugging. Eclipse’s IDE is more robust, more powerful and, well, integrated.
