Using CRCgen on Microcontrollers

To use the CRCgen utility, perform the followings steps.

  1. Create a file calc_crc.crc in the Project/Project_Settings/Linker_Files directory.
  2. Configure the post-linker to use it.

    Listing: Command line for post build
    "${MCU_TOOLS_HOME}/bin/crcgen.exe" "${BuildLocation}/
${BuildArtifactFileName}" -crc "${ProjDirPath}/Project_Settings/
Linker_Files/calc_crc.crc" -o "${BuildLocation}/
${BuildArtifactFileName}.crc.elf"

    This command line uses several Eclipse variables:

    • ${MCU_TOOLS_HOME} : Points to the MCU folder inside the CodeWarrior for Microcontrollers v10.x installation.
    • $(BuildLocation} : Points to the output folder inside the project of build where the ELF file is located.
    • ${BuildArtifactFileName} : Points to the variable that contains the ELF file.
    • ${ProjDirPath}:Points to the project folder.
  3. Build the project.

    The post build step is executed and CRC of the application is calculated.
