Load Example Binaries on J721E

Note: Please configure EVM in NOBOOT mode for connecting and loading binaries via CCS. As EthFw demos are run via CCS, please configure J721E EVM in NOBOOT mode.

  1. Open Code Composer Studio and launch the Target Configuration previously setup

    Launch CCS Target Configuration
  2. Go to the View Target configurations and launch a target configuration is done by right clicking on it.
  3. Go to the View menu and then select Scripting Console

  4. Run the launch.js script located in the pdk_xx_xx_xx/packages/ti/drv/sciclient/tools/ccsLoadDmsc/j721e/ on scripting console to load and execute DMSC firmware binary. This step can take considerable time as it configures PLL etc. in the SOC via GEL files and configures DDR.

    After script completes execution you should see below in Debug window
