Stm32h7 spi dma not working

The spi handler goes to "HAL_SPI_STATE_BUSY_TX_RX" state as soon as i call the function "HAL_SPI_TransmitReceive_DMA" and it does not do anything, it does not even generate the clock signal. stable diffusion intel arc gpuThe CPU IChache and DCache are disabled and MPU is not used. english setter lemon belton

Step3: Go To The RCC Clock Configuration. The latest SPI versions feature embedded counters, hence SPI takes over control of programable counters actions via the SPI configuration. Unfortunately this memory is used as default in some projects including examples. Sep 18, 2018 · On other STM32 controllers you can select the DMA trigger interrupt to be e.

Problem is, after the trigger has started your first DMA transfer it has to be changed to SPI RX buffer empty trigger which can not be done automatically.

So, I have bought 2 NUCLEO-H743ZI, one to be the master, the other to be the slave.

In this document, the set of control signals required for the DMA request/acknowledge protocol is not explicitly described and it is referred to as peripheral DMA request line.

Cite. I did get the SPI to work with LL drivers without DMA, so I believe that at least my wiring is correct. Mar 27, 2019 · for signal generation with synchronization from TIM6 and DMA). Please have a look at this article DMA is not working on STM32H7 devices, which explains the memory layout of the platform and the cache that have an impact on the DMA usage.

This will help other users find that answer faster. c), when it comes to SPI6, it uses a different DMA engine (DMA2) and goes through a mux BDMA_REQUEST_SPI6_TX/RX. .

You may find that by enabling the interrupts, the HAL state is able to reset your BUSY state back to READY, after that initial transfer completes.
