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...
Hi. First time using this forum.I'm using an STM32F103C8 (genuine, not bluepill clone).I've easily used DMA to take sensor data and store it in a buffer, this has worked without issue (see below): void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { if ...
Hi. I discovered an issue on UM3292 while trying to get PCF8574 I2C LCD module to work with my STM32U083C-DK. On page 22, it is stated that D14 is connected to PB9. However, it is actually connected to PB7. I have the MB1933C version. When I replaced...
I have a Beaglebone Computer configured as SPI Masted, and an STM32F446 configured as SPI Slave. I am simply sending 'HelloWorld' from the Beaglebone to the STM32, and trying to send 'ABCDEFG!' from the STM32 to the Beaglebone. The STM32 receives the...
