I have an STM32F103VET6 with multiple DMA Channels like UART2_RX, ADC, UART3_RX, UART3_TX, all at different priorities. The first one or two bytes of every DMA Channel becomes incorrect all of a sudden in runtime and corrects back only after power re...
Hello, We are using STM32H573AII3Q in our application. One external IC is interfaced with this uC through SPI lines. We are observing a tristate on MISO line. To investigate we isolated the uC and checked the MISO line. It is having a voltage level ...
Hello I'm developing RTOS environment of dual-core in STM32H757.In OpenAMP communication mode, CM4 is the master and CM7 is the slave, and I used SRAM4 to create SHMEM.I could refer to the examples provided by STM32, and I read the application note A...
Hello Error Definition1 : the return value of the OPENAMP_send function is 4. // RPMSG_ERR_NO_MEM?Error Definition2 : the return value of the OPENAMP_send function is -2007. // RPMSG_ERR_ADDR I'm developing RTOS environment of dual-core in STM32H757....
I use the internal RTC with MCU P/N:STM32U575.The schematic has two power supplies,RTC uses the VBAT power supply, others use the main power supply.My problem is that the RTC can count time normally, but when the main power is powered off and VBAT is...
Hi,I'm developing a custom bootloader.My freertos appl. is running well on debug mode in stm32cubeide while my freertos appl is on 0x08008000.MEMORY{RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K - 8/*FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 512K*/F...
Hi,I am trying to create a reliable communication in a noisy environment using RS-485 between 2 STM32 boards, one with STM32F302 that is receiving data from several sensors, performs some calculations and then send the data to a STM32H723 Board. On b...
Hello.STM32G431CBT6Is it possible to route the output from the comparator to the input of the Timer input? The reference manual says that this is possible, but there is no description. And in the comparator register there are no options for choosing ...
Hello, i'm wondering if it is possible to copy data from RAM to flash using DMA after unlocking the FLASH memory static const uint32_t src[4] ={80,20,30}; static uint32_t dst = 0x080E0000; __HAL_RCC_DMA1_CLK_ENABLE(); dma_handler.Instance = DMA1...
I want to use input capture mode in my stm32l432kc nucleo-32 board to measure the length of a signal from a sensor of mine. I have set it up the following way:int main(void) { // ... MX_USART2_UART_Init(); MX_TIM16_Init(); HAL_TIM_IC_Start_IT...
