- Attention
- As the wake-up R5 is the device manager, it needs to be started by the SBL. So it can not be loaded through CCS. It should be flashed and booted through SBL. This section is only applicable for MCU R5F Core.
- Note
- The steps on this page should be done each time EVM 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
Launch CCS
Launch Target Configuration
- You will see the AM62AX 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 ...

- 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
MCU_R5FSS0_0
Connect CPU
Reset 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.
