12.8. Summary

In this chapter, we got down to the practical aspects of using eCos by running through some examples. We started with an overview of the eCos build process, which we use for generating eCos libraries or RedBoot images.

After covering the details of the build procedure, we began our examples with a build and install of the RedBoot ROM monitor. This provided us with a method for downloading our application code onto our target hardware, as well as providing GDB debugging support on the target.

We then proceeded to construct an eCos library from our configuration. The eCos library was used to build our application. Next, we focused on loading our application using first RedBoot directly and then using GDB for debugging.

We concluded this chapter with a brief look at the eCos test suite and the simulators provided in the eCos framework. Although these examples were basic, they are good starting points for understanding the eCos development environment and provide a baseline for extending the functionality to meet your own requirements.

These examples enable you to evaluate the eCos real-time operating system and become familiar with the build and debug tools available. Moving on to more complex examples by incorporating additional features into the eCos configuration is a good next step.
