4. CCS Setup for J721S2¶

4.1. CPU names used in PDK vs CCS¶

Below table shows the mapping of names in PSDK RTOS and CCS

4.2. Step 1: Install CCS¶

1. Install CCS v11.0 : CCS can be downloaded from https://software-dl.ti.com/ccs/esd/documents/ccs_downloads.html#code-composer-studio-version-11-downloads

2. CCS installation details are available on https://software-dl.ti.com/ccs/esd/CCSv11/CCS_11_0_0/exports/CCS_11.0.0_ReleaseNotes.htm

3. This release is tested on below CCS version 11.0.0.00012

4. During installation, there is a ‘Setup’ step where you can select components. Be sure to select: “TDAx Driver Assistance SoCs & Jacinto DRAx Infotainment SoCs” as shown below:

5. Here after we’ll be referring to the CCS installation directory as ${CCS_INSTALL_PATH}

   In Linux, this will be

   ${HOME}/ti/ccsv1100/ccs
   

   In Windows, this will be

   C:\\ti\\ccsv1100\\ccs\
   

4.3. Step 2: Install CCS Chip Support Package and Emulation packs¶

4.4. Step 3: Setup CCS target configuration and GELs files¶

1. Create a CCS target config, you can name it J721S2_EVM.ccxml.

   • In Code Composer Studio, go to the File menu and select New -> Target Configuration File

   • Name the Target Configuration file as J721S2_EVM.ccxml and click Finish

   • Select Connection as Texas Instruments XDS110 USB Debug Probe, if you are using on board debugger (J3 usb connector)

   • Select Connection as Spectrum Digital XDS560V2 STM USB Emulator, if you are using Spectrum digital XDS560 USB debugger connected to JTAG Mipi connector (J16)

   • Select the Board as Jacinto7AEP shown below

2. Load the initialization script of the Cortex_M4F_0 core with the J7AEP Gels as shown below.

   • Open the Advanced tab of the target configuration file J721S2_EVM.ccxml

   • Go to CORTEX_M4F_0 under SMS_TIFSM

   • Set the initialization script

   • Gel files can be found at below path

     **${CCS_INSTALL_PATH}/ccs_base/emulation/gel/J7AEP_TDA4AL/J7AEP_SI.gel

4.5. Step 4: Load RTOS/baremetal application binaries thru CCS¶

1. GEL initialization

   • Open the launch.js script in an editor. Script is present in below path:

     ${PDK_INSTALL_DIR}/pdk_j721s2_{version}/packages/ti/drv/sciclient/tools/ccsLoadDmsc/j721s2/launch.js
     

   • ${PDK_INSTALL_DIR} is the path to your PDK installation

   • Edit the variable “pdkPath” with the absolute path of the pdk package, i.e ${PDK_INSTALL_DIR}/pdk_j721s2_{version}/packages

   • Open Code Composer Studio and launch the Target Configuration previously setup

     

     Fig. 4.5 CCS: Launch CCS Target Configuration

   • Go to the View Target configurations and launch a target configuration is done by right clicking on it.

   • Open the scripting console in CCS - Go to the View menu and then select Scripting Console

   • Load the launch.js script as shown below.

     

     Fig. 4.6 CCS: Launch script

   • Wait till the script finishes. This step can take considerable time as it configures PLL etc. in the SOC via GEL files and configures DDR. This will connect to the MCU_Cortex_R5_0 core.

   • After script completes execution you should see below in Debug window

2. Load and run the binaries in CCS. Debug as usual using CCS.

   • Now you can connect to any core and load the corresponding application binaries.

     

     Fig. 4.10 CCS: Loading the demo application binary

   • Go to the Run menu and then select Load -> Select Program to Load

   • In the Load Program window, browse to application binary you want to load.

   • Go to the Run menu and then select Resume to start executing demo binary.
