Unfortunately, codebench doesn't support M4 processors with external FPUs. Linaro also publishes a bare-metal ARM toolchain: http://www.linaro.org/downloads/ Look at the bottom of the page.

Martytoof posted:Oh no rush at ALL. I'm just dabbling in this stuff as a hobby. If you could just try to step through something simple that would be great The Dragon is exactly what you're looking for. Works great with AVR studio, and is a little flakier with the GNU tools. Occasionally, I'll set a software breakpoint in GDB, the program will fly off into la-la land, and when I reboot the chip, the breakpoint remains and I have to reflash the chip. I've heard reports that the Dragon is exceptionally ESD sensitive, so I laser-cut a case for it.

I've been using the Linaro Bare-Metal GCC package for playing around with Cortex M0/M3/M4 lately. http://www.linaro.org/downloads/ (Bottom of the page). The compiler works well out of the box, and support M4F floating-point units, but it isn't a complete toolchain. Libraries and linker scripts aren't always easy to find, and might not work out of the box anyway. Stellaris and STM chips haven't been too difficult to get up and running.

Kire posted:Has anybody ever used gdb for debugging a target from a host machine? I'm just curious, I learned about it in a class and it sounds complicated since gdb's command line interface gets very difficult to use very quickly, since terminals cannot display as much info as a GUI. So cross-debugging on a target seems really confusing, but kind of neat. I have found that cgdb makes the learning curve just a little softer: http://cgdb.github.io/

JawnV6 posted:You can totally slim down the dev process to gcc and a serial programmer. I use cgdb (http://cgdb.github.io/) along with the appropriate compilation of gdb, and a debugger. Maybe not as nice as Visual Studio, but it works very well across a lot of platforms.

NXP and STM ship binary versions of the emWin graphics library. I haven't used it myself, but it looks pretty decent. Whatever you do, stay miles away from those lovely 4D Systems Displays. Never again.

Primarily writing embedded code for life science payloads destined for the ISS, but there are other commercial and government contracts thrown in, as well. Almost everything's C or C++ on embedded.
