xilinx Spratan 3配置下载的问题

cqm239

于Xilinx的spratan3的下载问题在下载SPRATAN 3 的FPGA时,所有的配置芯片是XCF08P VO48 ,配置时经常出现下面的错误: PROGRESS_START - Starting Operation.
Validating chain... Boundary-scan chain validated successfully. '
1': Putting device in ISP mode... done. '1': Erasing device... done.
'1': Erasure completed successfully.

'1': Verifying device... '1':
Verifying Revision# '0'
Failed at address, 20612920
'1': Verification Terminated PROGRESS_END - End Operation.
Elapsed time = 55 sec.
请问是什么原因造成的呢?有时需要下载很多次才能下载成功.

估计是下载电缆不好
