DMA transfer program

Former Member

Hi, I am trying to learn DMA transfer.
And I want to read data from DMA, but I don`t know what should I do.(I am beginner at zedboard and embedded programming)

I think I should use Xilinx SDK, so I try to include header file #include <linux/dma-mapping.h>.
However, it makes error: fatal error: linux/dma-mapping.h: No such file or directory...

what should I do?...
