Hello, I download xilinx answer 65444 and I follow the ''Usage'' section flow of readme.txt file.
When I execute run_test.sh file, I meet problem below.
Can anyone help me to fix it? Thank you for your advice!
I modify the transfer size value from 1024 to 8192 of run_test.sh file and it test pass when transfer size value is 1024.
I do not know what the wrong message means.
