Development, compilation and configuration of MACL and EB based on MPC5744P

Summary

This note mainly records the development, compilation and configuration of MACL and EB based on MPC5744P.

Preparation

Prepare a project configured under EB. Here we take a routine as an example to illustrate.

Install and configure the compiler GreenHills or other compilers. Here we take GreenHills as an example.

Import routine

Open the EB tool, import the routine, click file->import and import according to the path. I have imported it here

Compile project:

The generated configuration code is under the file configured in EB, which is the output folder of the project.

This is code generated based on AUTOSAR 4.0.3. These codes can be used by compiling them with the upper-level code. Here, we use the command line to compile together with the application code of the routine.

Let’s take a look at the routine folder first

The toolchains folder toolchains contains

If there is no build.bat in the project, we need to create a new one and add the following content to copy the code generated by EB to the cfg directory.

Build.bat will call launch.bat

Here we need to modify launch.bat

According to the instructions, if there are no paths to these tools in the environment variables, you need to modify the EB and compiler paths. If these already exist in the environment variables, there is no need.

Open the command line window, go to the project directory, execute build.bat, and compile.

If everything is configured correctly, the elf file will be generated after compilation is completed,

These intermediate generated .o files, the final elf file and the map file are all located in the bin directory.

You can modify the configuration and recompile to adapt to your own board. At this point, the entire process has been introduced.
