As for DMA usage, you can refter to linux BSP for i.MX28, in some device drivers, DMA was used.</P><P></P><P>Regards,</P><P>Weidong</P></BODY></HTML> Thu, 12 Nov 2015 07:14:15 GMT https://community.nxp.com/t5/i-MX-Processors/How-to-accelerate-to-read-or-write-FPGA/m-p/402777#M59656 weidong_sun 2015-11-12T07:14:15Z
