Is it ok to use interrupt vectors which are 'reserved' inside or even beyond the vector table?We need to put an RTOS semaphore from an interrupt with higher priority than kernel scheduler interrupt (which is forbidden). Currently we use an interrupt ...
Hi,please help me figure out priorities in my project.So, I'm using:SDIO 4 bit + DMAUSB Composite Device = CDC + MSC with VBUS detection on PA9 pin.I configured PA9 as EXTI on Rising/Falling edge. For now i just want to light a diode when USB conecti...
Hi guys, looks after using "portYIELD_FROM_ISR(pxHigherPriorityTaskWoken);" the program gets thrown into this PORT: ARM_CM7 HEAP: HEAP4 .section .text.Default_Handler,"ax",%progbits Default_Handler: Infinite_Loop: b Infinite_Loop .size Default...
Hi,I have used FreeRTOS_AMP_Dual_RTOS as example and I can sent a single interrupt from CM7 -> CM4, but I cannot clear the line after the first interrupt so that I can sent a second one. Do you have an example to sent cyclic interrupts?BR
Hello! We are having problems with F303 during the task of updating form STM32F072RBT6 to the STM32F303RBT6 of MCUs .I have tried all firmware with the use of NUCLEO-F303RE .To test it out more ,I have designed an application that make NUCLEO LED per...
The HAL driver, HAL_HSEM_IRQHandler() disables itself by clearing bits in it's IER register. I don't want it disabled so I have to re-enable it in my HAL_HSEM_FreeCallback(). Is it desirable that it is disabling itself? I'm using the STM32H755.
I’m using STM32Cube MX 6.2.1, STM32Cube IDE 1.6.1 and STM32Cube_FW_H7_V1.9.0 for a STM32H7A3 project. As recommended, I configured the HAL time base source to a timer other than systick. (TIM17) If I understand correctly, FreeRTOS uses systick and se...
Hello, I am working on a project with an STM32f446 and I need to disable all interrupts while executing a specific critical function. I put in my code the following lines : __disable_irq(); Critical_function(); __enable_irq();But I still...
I want to use external event interrupt in freertos v2. I found when I set one pin with external event interrupt with freertos enable in stm32cubemax, I will miss exti1_handler() global interrupt function.right? is it possible to enable it in freertos...
Hello Everyone,Hope all are doing well.I am currently working with a board based on STM32L4R5 in FreeRTOS environment.I have two UARTS and some GPIO connected.I have one task monitoring the UART data. Both UART have an associated ISRThese ISR place t...
