Several days ago, you give me the answer that libiio can be compatible with xilinx dma.
yesterday I successfully lauched the dma to transfer using libiio with xilinx simple dma,
the driver used with dma is xilinx_dmac(I noticed that this driver belongs to you, "analog
2012 copyright , larsc ",), but the xilinx dma driver doesn't fit for iio device(if I use xilinx
dma driver, the boot process will not find ad9265_lpc iio device).
Now with analog dma driver, everything seems go right, except that when I call "iio_buffer_refill",
the returned bytes length can't exceed a maxim number 64KB, I don't know why, I need a 8MB
buffer .In my hdldesign, the address assigned to dma register is 64KB, is it due to that the issue
