CCS Launch, Load and Run

The steps on this page should be done each time EVM is power cycled or when a new CCS session is started.


A quick recap of the steps that need to have been done before you proceed

  • Make sure you have installed CCS as mentioned in Download, Install and Setup CCS
  • Make sure the UART port used for console is identified as mentioned in Setup UART Terminal
  • Make sure you have the EVM power cable, JTAG cable, UART cable connected as shown in Cable Connections
  • Make sure you have done the steps for a SOC initialization method as per SOC Initialization
  • Make sure the UART or CCS console logs on doing EVM POWER-ON indicate that SOC initialization is successful
  • Make sure you have built the example of interest as mentioned in Build a Hello World example

Launch CCS

Launch Target Configuration
  • You will see the AM62X target configuration in the "Debug" window as shown below

Target Configuration After Launch

Load and run example binaries

  • POWER-ON the EVM
  • If SBL NULL is flashed on the board by following steps in Flash SOC Initialization Binary, wait for the following messages from UART
      Starting NULL Bootloader ...
      DMSC Firmware Version 8.4.7--v08.04.07 (Jolly Jellyfi

  • If initialization is done by following steps in SOC Initialization Using SPL, wait for the Linux to be up on the A53 core.
    Linux terminal
  • Connect the target CPU of interest if not already connected. For the "hello world" example this is BLAZAR_Cortex_M4F_1

Connect CPU
  • Reset the CPU

Reset CPU
  • Load program on the CPU

Load Program
  • When using makefiles to build,
    • In the "Load Program" dialog, select "Browse" and select the program from examples/{example folder}/{board}/{cpu}_{os}/{compiler} as shown below for the "hello world" program.

Select Program for Makefile Build
  • When using CCS projects,
    • In the "Load Program" dialog, select "Browse Project", select the project and then select the program as shown below,

Select Program for CCS Projects Build

Select the Program from CCS Project
  • After the program is loaded, you will see the program is halted at "main" as shown below

Program at main()
  • Depending on the example you are running, you may need to load more programs on other CPUs for the example to work as expected. Typically, this is needed for multi-core interprocessor communication (IPC) examples. For the "hello world" program shown above, no more programs need to be loaded.
  • Select "Resume" to run the program and debug using the various CCS debug options

Run the Program
  • The program output will be seen on CCS console, and/or UART terminal, if enabled. Below shows a sample output on both CCS console and UART console, after running the "hello world" program.

Run the Program

Re-load and run example binaries

  • Here simply repeat the steps shows in Load and run example binaries
  • It is especially important to "reset the CPU" before reloading the program.
  • In most cases, you don't need to power-cycle the EVM to reload the program or load a new program.
  • In some cases, depending on whether the previous program execution was successful or not, the CPU or some SOC peripheral may be in a exception or hang state. In this case program reload may not work.
    • SOLUTION: Power cycle the EVM and repeat all steps shown on this page.
