ARM Development

My current development environment includes an ARM Cortex-A8 / TI DM3730 based BeagleBoard-xM and the Flyswatter2 JTAG Debugger. As part of my introduction to the environment, I modified the XLoader boot loader and developed a set of tools by borrowing from the Windows 8 DDK/SDK and Visual Studio C++ (MSVC) ARM compiler and assembler.  Using this Microsoft ARM tool chain generates COFF based images rather than ELF as with the GNU toolchain.  To address COFF images, I also created a coff2bin tool to generate the loader image from the linked image.

My plan is to modify the loader to expose a KD interface so that debugging can be performed with WinDBG rather than GDB.

These efforts are really only intended to gain more low-level experience on the ARM hardware, demonstrating how to configure the MSVC tool chain to generate the relevant Thumb-2 code.

My current public GIT repo is at https://github.com/bawoodruff/BeagleBoard where I will keep a shadow of the MSVC build environment that I’m using and a set of scripts to populate the tools directories based on installed DDK/SDK/MSVC tool chains.
