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.

    Hi,
     
    I have followed the step with Xilinx_Vivado_SDK_Web_2018.2_0614_1954_Lin64.bin and petalinux-v2018.2-final-installer.run.
     
    When I try to build peta linux I get the following error in Lab1 .
     
    Can you help me on same.
