program hangs after using SPI_TransmitReceive_DMA

[Dvan .8]

My program hangs after the return statement.

        pDataDMA = pData->data();
        HAL_StatusTypeDef val = HAL_SPI_TransmitReceive_DMA(&spih, pDataDMA, pDataDMA, pData->size());
        if (val != HAL_OK) {
            Error_Handler();
        }
        return;

Found the problem. Had a while(1) in the callback
