Honored ContributorI check idea with change the ALT_DMA_RX_STREAM_ON to ALT_DMA_TX_STREAM_ON in the IOCTL request.
All init steps passed correctly. But program haalted after call "alt_dma_rxchan_prepare". Program passes to an infinite cycle of ISR from DMA (i set break point in alt_avalon_dma_irq function). The first time ISR ocurred before programm return form alt_dma_rxchan_prepare, after write to DMA_CONTROL register. In ISR apdated DMA slot information, and programm go to infinite ISR cycle, however request for data send to SHARC processor not sended and no data was sended to SPI. This is HAL bug?
