There is a rare issue where the DMA operation occasionally stops during the burst transfer of data from external SDRAM to eMMC via DMA. I’m having difficulty identifying the exact cause, so I’m posting here to see if anyone has any good ideas.The har...
I am a noob in electronics and i am trying to make a quadcopter drone.I found about stm32f411ceu6 inav firmware on internet github. I only used arduino before and this stm32f411ceu6 was my first one.I connected it with my laptop in dfu mode and used ...
Hello,I am implementing UART RX reception using DMA, but I am encountering an issue where the data is not correctly updated in the memory buffer connected to the DMA. Below is the code I configured. #define DMA_BUFFER_SIZE 10 uint8_t dma_buffer[DMA_...
Hi,This is using the STM32H7S78-DK.So I have a stm32cubeide project containing two sub projects1. `STM32H7S78-DK_Appli`2. `STM32H7S78-DK_Boot``STM32H7S78-DK_Boot` is not changing, code changes are in `STM32H7S78-DK_Appli`.The only way I can find to d...
I am progressing on porting the CubeU5 project for STM32U575I-EV as Ux_Device_CDC_ECM to a NUCLEO-U575ZI-Q board: The USB enumeration seems to work: I hear the sound and I see also an USB "STM32 CDC ECM" device.BTW: very important to go with the righ...
My USB ECM project on NUCLEO-U575 and NUCLEO-U5A5 - it works now, on all OS platforms.https://github.com/tjaekel/STM32U5xx_USB_ECM This project and demo for a STM32U575I-EV (where I have converted from) needs a vendor driver on Windows.Windows does n...
Hello,I am using a bog standard, new, out of the box Nucleo-wba52cg.For some reason I can't get PA8 aka GPIO_23 to pull lower than about 1.6V?I discovered this when running the TIM_OCToggle example program. TIM_OCToggle uses TIM2 to toggle pins on e...
The manual I have for the STM32U585 describes the Independent Watchdog (IWDG) peripheral and says it has an Early Wake-Up Interrupt (EWI) feature. The manual says "Wake-up from Stop with interrupt is supported only in Stop 0, Stop 1, and Stop 2 mode...
I'm new to STM32. I made a custom board using STM32H7S3V8T6, but I think the HSE OSC configuration is failing. If I build main.c in (in Boot, not Appli), if (HAL_RCC_OscConfig(&RCC_OscInitStructure)!= HAL_OK) This part doesn't make HAL_OK, so this go...
Posted on April 14, 2018 at 23:13Hey everyone,My app based on STM32CubeF7 Firmware Package V1.11.0 / 23-February-2018 gets stuck in SDMMC_GetCmdResp1() during directory scan randomly - it can stuck just after switching on or after 2 minutes of worki...
