I was able to reproduce these results on windows! (not that linux is bad, its actually really great)

HOW?

I got:

arm-linux-gnueabihf (gdc) from [1] OpenOCD [2] ST LINK DRIVER from [3] and GDB as part of [4]


And followed the instructions given for the most part. There is some difficulty with path and of course the commands are a bit different. Honestly It was just kinda awesome that it worked! I'll admit i got that "embedded things that work high". Also I was curious if any new development has occurred? Is this article dated in any way? can i do more and better coding in d? Where can i find information on formatting the memory layout? Thanks!


I'm not sure how you were able to get a compiler binary compiled for Linux to run on Windows, but I suppose if GDC were compiled with MinGW it might work.

My development on this has stalled due to https://issues.dlang.org/show_bug.cgi?id=14758. GDC is currently being merged with the 2.067 compiler front end which will finally bring us volatileLoad/Store. I have another example at https://github.com/JinShil/stm32f42_discovery_demo but I really need support from the DMD compiler team to take this any further.

Don't be mislead the arm-linux-gnuabihf is about the aplication binary interface this has floating point but it doesn't really matter. I found out this would work from this[5] post on the dlang forum. On the GDC page under the section -Windows X86 32bit (i686-w64-mingw32) --http://gdcproject.org/downloads/binaries/i686-w64-mingw32/arm-linux-gnueabihf_2.066.1_gcc4.9.2_f378f9ab41_20150405.7z

Also I am glad that GDC is being merged! Progress is always great to see on projects.
