Introduction

This example demonstrates the usage of the SDL R5 CCM module. The example shows how to setup and use the R5 CCM Safety Diagnostic operation.

Use Cases

Use Case	Description
UC-1	self test on R5 CCM.
UC-2	self test with error force on R5 CCM.

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am263x-cc
Example folder	examples/sdl/ccm/sdl_ccm_example/

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
