Spartan series impact downloader program download problem [Copy link]

Hello everyone. I recently encountered a problem while doing xilinx development and would like to ask for advice. I am using the spartan series XC3S200A chip, programming with VHDl language, the downloader is Platform Cable, the circuit board download interface is designed with IDC10 core, the downloader interface is IDC14 core, a small adapter board is used in the middle, and the circuit board is electrically connected to the burner with a green light. When using impact to download the bit program to create a new one, an error is reported. The error is as follows: There are many unknown devices being detector. Press yes to continue or press no to stop. Then the downloader cannot detect the download failure. How can I solve this problem? Please advise.

Maybe your line is connected wrongly. Please check the connection instructions of Xilinx.

Are you referring to the wiring of the circuit board or the wiring of the downloader adapter?

Does it refer to the link method of the chip, programming eeprom, and JTAG?
