I have my FPGA (Vertex 5)-XC5VLX110 connected to ISP-XCF32P in master serial mode. Downloading MCS to ISP done successfully through JTAG. But once I restart my system my ISP is not configuring my FPGA.
I checked the status of fallowing pins:
1. INIT goes high and stays at high.
2. PROG Pin goes high and stays high but
3. There is no BIT toggling in DIN pin
4. My CCLK continuously toggling at 2.73MHz
5. My DONE pin did not go high at all
6. My Status register is as fallows.
