I have purchased ML505 virtex5 based kit for PCIe testing. It has one pre-loaded compact flash with some in-built testing environment. My uses is PCIe testing which this compact flash doesn't have the testing utility nor Xilinx having any utility for the same. I have contacted Xilinx but didn't get any proper answer. As per user guide it requires external CF reader for copying .ace file to compact flash after executing using core gen for PCIe. Does any body know how to read/write compact flash on-board(ML505), any utility to copy any file to compact flash, anybody having?? I don't have CF reader. I want to copy generated .ace file to CF using on-board ML505. Your early reply is highly appreciated.
