I'm facing an issue with reading and writing data on an SD card using SPI and FATFS on an STM32F767ZIT6 microcontroller. When I don't enable FreeRTOS, the SD card operations work fine. However, when I enable FreeRTOS, the SD card operations fail. Dur...
HI All,I have created a project to integrate sd card with STM32G474RE nucleo board while using SPI interface. After running the project I am able to initialize the sd card properly but while mounting the sd card, I am getting one error like: "FR_DISK...
Dear all,I try to read out ADC-Data, that is streamed from an external adc (AD7768) out to the uC. What I want to do is to more or less directly stream out the data via USB CDC.Therefore, I planned to use the DMA between the SPI and USB. However, thi...
Hi everyone!I'm trying to transmit some data using SPI2 on a NUCLEO-H743ZI board (only TX). To do it fast I'm using DMA with HAL_SPI_Transmit_DMA(), but it returns with an error (from line 1465 in stm32h7xx_hal_spi.c):/* Packing mode management is en...
Hello,I need to transfer more data, than I could afford to store in memory with an SPI Master. So I thought to use the circular DMA to update the data using HAL_SPI_TxHalfCpltCallback and HAL_SPI_TxCpltCallback.But how can I stop the SPI transmission...
Hi guys, I'm hoping to find a wizard at FatFS who can help me. So my current set up is, stm32f446re microcontroller, with this micro SD card adapter, I have two SD cards at my disposal, a 2GB Sandisk card and a 16GB Samsung SDHC card. Both cards have...
I have a application with STM32F429 with RTOS and SPI µSD .I have a singke task forr write in SD card and some time goes in HardFault_Handler ()It is possible thei is caused by stack overflow ?How can I check if the stack pointer goes in overflow ?Th...
I have SPI set in Master Receive Mode Only and my code does work when not passing data to DMA.
my host interaction with STM32G431C8T6 SPI bootloader are functioning for a lot of jobs such as RW, but not for the whole-chip CRC. Here is the Logic analyzer captured data:Host=>BL, BL=>Host5A, A5A1,A55E,A5 cmd to run whole chip CRC00,A5......00,A50...
When doing triggered (EXTI2 line) DMA transfer with SPI in circular mode I often don't get the expected result. If I do the DMA transfer (non-circular) from the EXTI2 interrupt everything is fine.Code transmit 10 bytes, receives 10 bytes each transfe...
