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
To run the example on a53ss0-0, a53ss0-1, a53ss1-0 and a53ss1-1 in FreeRTOS-AMP mode, run the hello_world_freertos-amp_sbl_uart_hs_fs.cfg file using SBL UART or load and run through CCS individually

Sample Output

Shown below is a sample output when the application is run,

Hello World!

FreeRTOS-AMP Sample Output

Attention: Output from a53ss0-1, a53ss1-0 and a53ss1-1 cores are log to the Shared memory, can be viewed via a53ss0-0 on which log reader is enabled

Shown below is a sample output on UART0 console when the application is run,
