AXI Transer between linux and FPGA

shanbhagm

Hi,

My requirement is to transfer data from FPGA to ARM(linux) and back. I want to use the AXI bus interface.

Can some one point me to aworking example of data transfer from linux to the FPGA and vise versa.

A quick help will be appreciable.

    I installed 2017.4 and I get same error:

    Are you sure it worked with 2017.4?
