Hi, I see that xSemaphoreGiveFromISR() not functional from ISR in STM32F746G-DISCO board
HAL_GPIO_TogglePin is working fine when it is called in ISR. But, xSemaphoreGiveFromISR is not working.
Is there any STM32F746NG configuration is missing to make it work with STM32F746NG?
NOTE:
1. Target board & CPU: STM32F746G-DISCO, STM32F746NG
2. FreeRTOS project is created from STM32CubeMx
3. Used TIM3 for Timebase Source and TIM2 for 1sec interrupt generation using internal clock
4. Refer below section for definition of configKERNEL_INTERRUPT_PRIORITY and configMAX_SYSCALL_INTERRUPT_PRIORITY

HAL_GPIO_TogglePin(GPIOI,GPIO_PIN_1);
HAL_UART_Transmit(&huart1, txData, 20, 5);
osDelay(100);

HAL_IncTick(); //TIM3 used for Timebase Source

LED blink working fine when below SemaphoreGiveFromISR commented */
xSemaphoreGiveFromISR(myBinarySem01Handle,NULL);
