WebI had a very similar issue. First call to HAL_I2S_Transmit_DMA worked. If i called it again in the completion handler also ok. Every now and then due to other things going on i did not process the interrupt in time so I had some recovery code that re-initiated the transmit by calling HAL_I2S_Transmit_DMA again ... but although it returned ok the completion … Webhspi->RxXferCount = (hspi->RxXferCount >> 1) + 1; /* Set the SPI Rx DMA transfer complete callback because the last generated transfer request is the reception request (RXNE) */
