A template for projects based on the TMS570 microcontroller (Launchpad XL2, TMS570LS1224).

You can install it from here.

TMS570 is a big-endian part (BE32), GCC libraries are compiled only for little-endian systems. Recompile the gcc libs is required.

This tool has the big endian libs so no workaround is needed with this option.

• project/cmake : Contains the toolchain (compiler, linker and options definition), the linker script and some project specific cmake variables.

• project/BSP/HALCoGen : Software component containing the basic software package, this package is generated from HALGCode Tool, here there are multiple examples of projects that can be imported into HALCoGen to reconfigure and generate a new BSP.

CMake is a tool for generation and automation of code. The name is an abbreviation of cross platform make. It is a multiplatform, open-source tool that can generate Makefiles (or different build system projects like Ninja) from a simple and more readable configuration file. CMake in a nutshell is a syntax to describe a project and the compiler environment so it can be abstracted from the final build system file (Makefiles, Ninja.build, Eclipse .cproject, etc)

Ninja, in other hand, is a build system tool meant to replace Makefiles. It is focused by design to run as fast as possible. It already knows the number of cores of your machine, so it dynamically decides when and how to parallelize the build process.

The build process is pretty straightforward, just create a build folder, invoke CMake over the project folder and then run ninja (I recommend to use Ninja instead of Make).

$ #Assuming you are at the root folder of this repo:
$ mkdir build
$ cd build
$ cmake ../project -GNinja
$ ninja

After the compilation, the artifacts are located at the new build/bin folder. This will generate ELF, S19 and HEX files. You can now load the binary to the microcontroller using OpenOCD and see the leds blinking.
