Hi all,I've been struggling so much to get wake from uart working on this board. It looks like it should be simple, I have this code which I am pretty sure should be everything needed, but it just doesn't wake up when I send data to the serial port.C...
Hi,Looking into STM32CubeN6\Projects\STM32N6570-DK\Examples\SD\SD_ReadWrite_DMA example,I see that quite heavy operations are used:SCB_CleanDCache_by_Addr (aTxBuffer, BUFFER_SIZE); // ... SCB_InvalidateDCache_by_Addr (aRxBuffer, BUFFER_SIZE);while th...
I'm running into a pixel mismatch issue when trying to capture frames over DCMI from a [B-CAMS_OMV with an OV5640 sensor board attached. I've used CubeMX and the stm32-disco F746 development board to successfully collect RGB565 and JPEG image compres...
Hello,I have 2 STM32 Nucleo F746ZG boards, and I am trying to use one board (MCU 1) to program the second board (MCU 2) through its default bootloader through code. To do so, I used the following command in the MCU2 to start its default bootloader:#d...
I use the stm32g0b1 microcontroller to USB Host. I use the HAL library from STMicroelectronics. Class for FS IP: Communication Host Class (Virtual Port Com). And it works great with other microcontrollers that use Class for FS IP: Communication Devic...
Hi everyone, I'm working on a project using an STM32H743 and LwIP (v2.1.2) without an RTOS (NO_SYS=1), and I've been debugging persistent issues related to LwIP's heap allocation and MPU configuration. After days of digging, I’d really appreciate the...
Hello,I'm using NucleoU575 with CubeMx and I want to make a file system on my SD card.I want to use FreeRtos but there are no Fatfs in CubeMx and the FileX cannot work with FreeRtos (image). Is there anyway i can use Fatfs with STM32U5 ?Thank you.
Hello,What is the simplest and best way to implement encrypted firmware update via DFU? I plan on building a custom bootloader but have not found any recent existing projects. I tried STM32-AES-Bootloader but it is setup for STM32F10 and I am using...
I have a project working on the NUCLEO-N657X0-Q with FSBL and an application. In total I am using under 1MB of the 64MB flash this board has. I was wondering if it was possible to segment off the rest of the flash to be used as a mass storage device ...
Hi ST Community,I'm encountering an issue using the following function in STM32Cube HAL v1.11.3: HAL_UARTEx_ReceiveToIdle_DMA(&CLI_PORT_HANDLER, (uint8_t*)&cliPortRxBuff, sizeof(cliPortRxBuff)); HAL_UART_RegisterRxEventCallback(&CLI_PORT_HANDLER, (p...
