CCS Launch, Load and Run

Table of Contents

• Prerequisites
• Launch CCS
• Load and run example binaries
• Re-load and run example binaries

Note

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

Prerequisites

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 IDK power cable, JTAG cable, UART cable connected as shown in Cable Connections
• Make sure you have done the steps for a SOC initialization method
  • Recommended method is Run the SOC Initialization Script
• Make sure EVM boot mode switch is setup correctly based on the SOC initilization method
  • For the RECOMMENDED method, Run the SOC Initialization Script, the boot mode should be NOBOOT MODE
• Make sure the UART or CCS console logs on doing IDK POWER-ON indicate that SOC initization is successful
• Make sure you have built the example of interest as mentioned in Build a Hello World example

Launch CCS

• Launch the target configuration created with Create Target Configuration

Launch Target Configuration

• You will see the AM65X target configuration in the "Debug" window as shown below

Target Configuration After Launch

Load and run example binaries

• POWER-ON the IDK
• Connect the target CPU of interest if not already connected. For the "hello world" example this is MAIN_Cortex_R5_0_0

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 dont need to power-cycle the IDK 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 IDK and repeat all steps shown on this page.
