Introduction

Use Cases

Supported Combinations

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run

Steps to Test the Example

• CCM example should only be tested in QSPI boot mode and should not be tested in no boot mode with debugger connected.
• Follow the below procedure to test the CCM and CCM_VIM example.
  1. A quick recap of steps done so far that are needed for the flashing to work
     • Make sure the UART port used for terminal is identified as mentioned in Setup UART Terminal
     • Make sure python3 is installed as mentioned in Python3
     • Make sure you have the EVM power cable and UART cable connected as shown in Cable Connections
  2. Build the hello world application as mentioned in Build a Hello World example, Build a Hello World example
  3. As part of the build process in the final step a file with extension .appimage is generated. This is the file we need to flash.
  4. When building with makefiles and single-core projects, this file can be found here

        ${SDK_INSTALL_PATH}/examples/sdl/ccm/sdl_ccm_example/{board}/r5fss0-0_nortos/ti-arm-clang/sdl_ccm_example.release.appimage
     

  5. A default configuration file can be found at below path. You can edit this file directly or take a copy and edit this file.

        ${SDK_INSTALL_PATH}/tools/boot/sbl_prebuilt/{board}/default_sbl_qspi.cfg
     

  6. Edit below line in the config file to point to your application .appimage file. Give the absolute path to the .appimage file or path relative to ${SDK_INSTALL_PATH}/tools/boot. Make sure to use forward slash / in the filename path. –file=../../examples/sdl/ccm/sdl_ccm_example/{board}/r5fss0-0_nortos/ti-arm-clang/sdl_ccm_example.release.appimage –operation=flash –flash-offset=0x80000
     • NOTE : edit sdl_ccm_example to sdl_ccm_vim for ccm vim example testing.
  7. Save and close the config file.
  8. Flash the application by follow the steps mentioned in the page, Flash a Hello World example
