[FAQ] TDA4VL-Q1: How can I port a C7x algorithm using Code Composer Studio?

Prerequisites:

1. Install CCS : https://www.ti.com/tool/download/CCSTUDIO/12.8.1
2. Install J721S2 Processor RTOS SDK :  https://www.ti.com/tool/PROCESSOR-SDK-J721S2
3. C7x CGT : https://www.ti.com/tool/C7000-CGT#downloads
4. Linker script  :  For J721S2 platform builds, use the linker script located at:  "dsplib/cmake/linkers/C7120/lnk.cmd", For builds targeting different C7x DSP variants, use the appropriate linker script found at: "dsplib/cmake/linkers"
5. Please follow the steps mentioned here to create a target configuration file for J721S2.

CCS Workspace for C7x Development ( Using existing example.cpp from DSP Library) :

Please complete the following steps to set up a new CCS project. 

• File → New → Project 

• A dialog box will appear. Select CCS Project from the options, and then click Next.

• Fill in the following fields for the newly created CCS Project:

  • Target: Select Custom C7000 Device/ Specify the EVM
  • Project Name: For example, DSPLIB_add_example
  • Compiler Version: Choose the appropriate C7x compiler version from the drop-down menu
  • Project Template: Select Empty Project, then click Finish

• The project workspace named DSPLIB_add_example will be created and displayed in the CCS Project Explorer window as follows:

• To add example.cpp and the linker script from the SDK:

  • Right-click on the project in Project Explorer
  • Select Add Files
  • Browse and select the required files from your local SDK directory, adding them one by one

• After adding all the required files, the project workspace will appear as shown below:

• Next, configure the project properties:  Right click on the project workspace → Properties
  • Under Build → C7000 Compiler, update the following settings:

Include dsplib → src path in the include option of C7000 compiler : 

Under Build → C7000 Linker, Include the lib paths as follows: 

• Then click on "Apply and Close"
• To build the project → Right Click on the project workspace → Build Project 
• After the build completes, an executable file will be generated in the corresponding build configuration folder (Release or Debug) within the project.
