在XPS中为我的系统生成的比特流下载到我的目标板时出现错误，请问如何解决？

大家好，
当我将在XPS中为我的系统生成的比特流下载到我的目标板时出现错误.jtag链是串行链，设备1是来自ACTEL的aglp125vs CPLD，设备2是目标FPGA SPARTAN3ADSP3400A.falowing是信息。

---------- INFO：iMPACT：583  - '2'：从设备读取的idcode与bsdl File.INFO：iMPACT：1578  - '2'中的idcode不匹配：Device IDCODE：00000001110000100111000001001001INFO
：iMPACT：1579  - '2'：预计IDCODE：00000011100001001110000010010011制作：*** [下载]错误1
我更改了download.cmd，如下所示：
setMode -bscansetCable -p autoidentifyaddDevice -p 1 -file etc / aglp125.bsdassignfile -p 1 -file etc / aglp125.bsdassignfile -p 2 -file implementation / download.bitprogram -p 2quit
但是当我用IMPACT下载比特流时，程序就成功了。
当我使用sdk编程fpga时也出现错误。错误显示如下：
程序FPGA failedERROR：无法下载位文件。
有没有人可以帮助我？
谢谢提前！

hi all,
there was a error when i download bitstream which generated for my systerm in XPS to my target board .the jtag chain was a serial chain ,which device 1 was a aglp125vs CPLD from ACTEL and device 2 was the target fpga SPARTAN3ADSP3400A.the falowing was the info.

   in the bsdl File.
INFO:iMPACT:1578 - '2':  Device IDCODE :        00000001110000100111000001001001

make: *** [download] Error 1

I has changed the download.cmd like the following:

setMode -bscan
setCable -p auto
identify
addDevice  -p 1 -file etc/aglp125.bsd
assignfile -p 1 -file etc/aglp125.bsd
assignfile -p 2 -file implementation/download.bit
program -p 2
quit

But when I download bitstream with IMPACT,the program was successed.
there was also a error when i use sdk to program fpga .the error was shown like this:
Program FPGA failed
ERROR: Failed to download the bit file.

is there anyone can help me ?
thanks advance !      -----------wangqueping
