STM32H7 SPI configured as Master with the Clock Phase and Clock Polarity 0 (mode 0). During the HAL_SPI_TransmitReceive() call, before the CLK the pulse is observed on the MOSI signal. Due to this the slave device is behaving differently. Agree the...

Thanks, Waclawek.jan for your suggestions. I couldn't find any information related to this in RM. Regarding the workaround, our system is not only generating the waveform, in parallel we also need to capture the data using the MISO line.For more info...

I would like to know the problem for hdma_memtomem_dma2_stream1.State not in HAL_DMA_STATE_READY after the data transfer. Is there any thing I am missing in the mentioned code.

STM32H7 SPI MOSI Signal changing before the CLK and observed the pulse

Using STM32CubeIDE project and MCU STM32H750. After calling HAL_DMA_Start() data is transferring, but the hdma_memtomem_dma2_stream1.State is still in HAL_DMA_STATE_BUSY. So calling the abort HAL_DMA_Abort() and transferring the next set of data
