@Frantz LEFRERE ,
I have done the following changes for the timer test.
In stm32l5xx_hal_conf.h file uncommented HAL_TIM_MODULE_ENABLED file.
Add FOllowing API in Nonsecure application main.c and called it after HAL_Init().
HAL_StatusTypeDef test_timer()
{
uint32_t TickPriority = TICK_INT_PRIORITY;
RCC_ClkInitTypeDef clkconfig;
uint32_t uwTimclock = 0;
uint32_t uwPrescalerValue = 0;
uint32_t pFLatency;
/*Configure the TIM6 IRQ priority */
HAL_NVIC_SetPriority(TIM6_IRQn, TickPriority ,0);
/* Enable the TIM6 global Interrupt */
HAL_NVIC_EnableIRQ(TIM6_IRQn);
/* Enable TIM6 clock */
__HAL_RCC_TIM6_CLK_ENABLE();
/* Get clock configuration */
HAL_RCC_GetClockConfig(&clkconfig, &pFLatency);
/* Compute TIM6 clock */
uwTimclock = HAL_RCC_GetPCLK1Freq();
/* Compute the prescaler value to have TIM6 counter clock equal to 1MHz */
uwPrescalerValue = (uint32_t) ((uwTimclock / 1000000U) - 1U);
/* Initialize TIM6 */
htim6.Instance = TIM6;
/* Initialize TIMx peripheral as follow:
+ Period = [(TIM6CLK/1000) - 1]. to have a (1/1000) s time base.
+ Prescaler = (uwTimclock/1000000 - 1) to have a 1MHz counter clock.
+ ClockDivision = 0
+ Counter direction = Up
*/
htim6.Init.Period = (1000000U / 1000U) - 1U;
htim6.Init.Prescaler = uwPrescalerValue;
htim6.Init.ClockDivision = 0;
htim6.Init.CounterMode = TIM_COUNTERMODE_UP;
if(HAL_TIM_Base_Init(&htim6) == HAL_OK)
{
/* Start the TIM time Base generation in interrupt mode */
return HAL_TIM_Base_Start_IT(&htim6);
}
else
{
printf("Fail to init Timer \r\n");
}
/* Return function status */
return HAL_ERROR;
}
Also, Add the following API in the stm32l5xx_it.c file
void TIM6_IRQHandler(void)
{
/* USER CODE BEGIN TIM6_IRQn 0 */
/* USER CODE END TIM6_IRQn 0 */
HAL_TIM_IRQHandler(&htim6);
/* USER CODE BEGIN TIM6_IRQn 1 */
/* USER CODE END TIM6_IRQn 1 */
}
The callback is also written in the main.c file as following
void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)
{
/* USER CODE BEGIN Callback 0 */
/* USER CODE END Callback 0 */
if (htim->Instance == TIM6) {
u32counter++;
}
/* USER CODE BEGIN Callback 1 */
/* USER CODE END Callback 1 */
}
All above modifications are done in a nonsecure application
Am I missing or missconfiguring anything?
