My spartan 3E with xc3s500e FPGA,xcf04 PROM and xc2c64a CPLD come across some problems when programming!When I burn bit file into my board,the ISE show"program successed",the xc_done lighting and work normally,but when I burn mcs file into my board ,software shows “program successed",the xc_done doesn't lighting!
Someone says that maybe I have erased the initial CPLD data,so I try to recovery it.
I burned "original_CPLD_design.jed" into my board,turn up a warning "the idcode read from the device does not match the idcode in the bsdl file"!(so sorry for my poor English!)
what can I do next?
ps:the CPLD xc2c64a package mode is VQ100
