FRET-FreeRTOS/FreeRTOS/Demo/ThirdParty/Template

Create a Test Project

Initial Setup

1. Create a new directory in the FreeRTOS Partner Supported Demos Repository or FreeRTOS Community Supported Demos Repository. The suggested name for the directory is <hardware_name>_<compiler_name>.
2. Create a project for your hardware and tool-chain in this directory.
3. Copy all the files in the FreeRTOS/Demo/ThirdParty/Template directory to your project directory:
   • IntQueueTimer.h
   • IntQueueTimer.c
   • TestRunner.h
   • TestRunner.c
   • RegTests.h
   • RegTests.c

Project Configuration

1. Compile the following additional files in your project:
   • All files in the FreeRTOS/Demo/Common/Minimal directory except comtest_strings.c, crhook.c , comtest.c ,crflash.c,flash.c, flash_timer.c and sp_flop.c.
2. Add the following paths to your include search path:
   • FreeRTOS/Demo/Common/include.
3. Call the void vStartTests( void ) function from your main function after doing all the hardware initialization. Note that this function starts the scheduler and therefore, never returns.

#include "TestRunner.h"

void main( void )
{
    /* Startup and Hardware initialization. */

    /* Start tests. */
    vStartTests();

    /* Should never reach here. */
    for( ; ; );
}

Set up FreeRTOSConfig.h

1. Enable tick hook by adding the following line in your FreeRTOSConfig.h:

#define configUSE_TICK_HOOK 1

2. Set the task notification array size to 3 by adding the following line in your FreeRTOSConfig.h:

#define configTASK_NOTIFICATION_ARRAY_ENTRIES 3

3. Enable printing by mapping configPRINTF to your print function. Note that configPRINTF calls are wrapped in double parentheses to support C89. If you have a thread-safe printf function, the following is what should be added in your FreeRTOSConfig.h:

#define configPRINTF( X ) printf X

4. Add the following defines in your FreeRTOSConfig.h:

#define configSTART_TASK_NOTIFY_TESTS             0
#define configSTART_TASK_NOTIFY_ARRAY_TESTS       0
#define configSTART_BLOCKING_QUEUE_TESTS          0
#define configSTART_SEMAPHORE_TESTS               0
#define configSTART_POLLED_QUEUE_TESTS            0
#define configSTART_INTEGER_MATH_TESTS            0
#define configSTART_GENERIC_QUEUE_TESTS           0
#define configSTART_PEEK_QUEUE_TESTS              0
#define configSTART_MATH_TESTS                    0
#define configSTART_RECURSIVE_MUTEX_TESTS         0
#define configSTART_COUNTING_SEMAPHORE_TESTS      0
#define configSTART_QUEUE_SET_TESTS               0
#define configSTART_QUEUE_OVERWRITE_TESTS         0
#define configSTART_EVENT_GROUP_TESTS             0
#define configSTART_INTERRUPT_SEMAPHORE_TESTS     0
#define configSTART_QUEUE_SET_POLLING_TESTS       0
#define configSTART_BLOCK_TIME_TESTS              0
#define configSTART_ABORT_DELAY_TESTS             0
#define configSTART_MESSAGE_BUFFER_TESTS          0
#define configSTART_STREAM_BUFFER_TESTS           0
#define configSTART_STREAM_BUFFER_INTERRUPT_TESTS 0
#define configSTART_TIMER_TESTS                   0
#define configSTART_INTERRUPT_QUEUE_TESTS         0
#define configSTART_REGISTER_TESTS                0
#define configSTART_DELETE_SELF_TESTS             0

Create and Run Register Tests

1. Fill the definitions of the following functions in the RegTests.c file copied in the Initial Setup step:
   • prvRegisterTest1Task
   • prvRegisterTest2Task
   • prvRegisterTest3Task
   • prvRegisterTest4Task
2. Define configSTART_REGISTER_TESTS to 1 in your FreeRTOSConfig.h:

#define configSTART_REGISTER_TESTS                1

3. Build and run the register tests. The output should look like the following:

No errors
No errors
No errors
No errors

Setup and Run Interrupt Nesting Tests

1. If your hardware does not support interrupt nesting, skip this section.
2. Fill the void vInitialiseTimerForIntQueueTest( void ) function in the IntQueueTimer.c file copied in the Initial Setup step to initialize and start a hardware timer. Make sure that the timer interrupt runs at a logical priority less than or equal to configMAX_SYSCALL_INTERRUPT_PRIORITY. The following is an example for ARM MPS2 which starts TIM0 timer:

void vInitialiseTimerForIntQueueTest( void )
{
    /* Clear interrupt. */
    CMSDK_TIMER0->INTCLEAR = ( 1ul <<  0 );

    /* Reload value is slightly offset from the other timer. */
    CMSDK_TIMER0->RELOAD = ( configCPU_CLOCK_HZ / tmrTIMER_0_FREQUENCY ) + 1UL;
    CMSDK_TIMER0->CTRL   = ( ( 1ul <<  3 ) | ( 1ul <<  0 ) );

    NVIC_SetPriority( TIMER0_IRQn, configMAX_SYSCALL_INTERRUPT_PRIORITY );
    NVIC_EnableIRQ( TIMER0_IRQn );
}

3. Either install void IntQueueTestTimerHandler( void ) function as the timer interrupt handler or call it from the timer interrupt handler of the above timer. The following is an example for ARM MPS2 which calls IntQueueTestTimerHandler from the TIM0 handler:

void TIMER0_Handler( void )
{
    /* Clear interrupt. */
    CMSDK_TIMER0->INTCLEAR = ( 1ul <<  0 );

    IntQueueTestTimerHandler();
}

4. Define configSTART_INTERRUPT_QUEUE_TESTS to 1 in your FreeRTOSConfig.h:

#define configSTART_INTERRUPT_QUEUE_TESTS         1

5. Build and run the tests. The output should look like the following:

No errors
No errors
No errors
No errors

Running All Tests

1. Define all the configSTART_<Test_Name>_TESTS macros to 1 in your FreeRTOSConfig.h.
2. Build and run the tests. The output should look like the following:

No errors
No errors
No errors
No errors

3. If you cannot fit all the tests in one binary because of Flash or RAM space, you can run tests one by one or in groups by defining configSTART_<Test_Name>_TESTS macros to 0 or 1 as needed.

Add README

Add a README.md file in the project directory with the following information:

• Link to the hardware page.
• How to setup tool-chain.
• How to build and run the project.
• Any other relevant information.
