I am trying to use SPI and DMA in a STM32H7, but it is not worling. 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...

Sorry for the late. In the end i had to change it in order not to use DMA and i could not test it more time. I did not find the issue. Thanks for the help

SPI initialization: hspi2.Instance = SPI2; hspi2.Init.Mode = SPI_MODE_MASTER; hspi2.Init.Direction = SPI_DIRECTION_2LINES; hspi2.Init.DataSize = SPI_DATASIZE_8BIT; hspi2.Init.CLKPolarity = SPI_POLARITY_LOW; hspi2.Init.CLKPhase = SPI_PHASE_1...
