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...
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[D...
Can Single DMA channel be used for multiple DMA Streams?As per Table 43. DMA1 request mapping in reference manual, Can I use Channel 6 for Stream0 (TIM5_CH3), Stream 3(TIM5_CH4), Stream 4 (TIM5_CH2).I understand that Single stream I cannot use more t...
Hello,I have been utilizing the OTG_HS peripheral on an STM32U5A5 to act as a USB host. I am using the USBx stack in a non-secure application and initializing the peripheral as follows: VOID USBX_APP_Host_Init(VOID) { MX_USB_HCD_Init(); ux_host...
Hi all,I'm using an STM32F413 to write to an uSD card via DMA over SDIO. I'm using the FATFS (R0.12c). Up until now, I've been writing to the SD card by firstly mounting, opening the file, write, write, write... then closing and unmounting. I'm writ...
Hi All,Probably easy question, I would like to use DMA with QSPI (e.g. HAL_QSPI_Receive_DMA) but STM32CubeIDE/MX (1.16.0) is not giving me any options to configure it.There are no options, my parameter settings are belowQSPI is working fine in Indire...
Hello, I have been prubbing to run SPI transmission using DMA for some time now. So far I am trying to send a variable, but something is not working. Without DMA it works without any problem. Would anyone be able to help?
I am using stm32f779I eval kit. I am using example UART_HyperTerminal_DMA by en.stm32cubef7.I am trying to implement UART in DMA mode to transmit a simple string.So I have used CubeMX to generate the code and I have configured UART1 TX DMA in normal...
I have a couple dozen of custom boards with STM32G4s on them. These boards are all 'identical' and the software being loaded on them is the same. BOOT0 pin is currently floating so on my initial load I held it to ground and changed the option bytes v...
I am using STM32H7B0VBT6 MCU.i want to transmit data using UART with DMA in normal mode.i am using "HAL_UART_Transmit_DMA(&huart4, &UART4_array[0], UART4_ARRAY_SIZE);"it sends only once , next time it do not work. Where i am doing wrong ? am I using ...
