Hi

I'm trying to develop an IoT board with XC3S400AN-5FTG256C.

I bought 5 XC3S400AN-5FTG256C chips from China online market. I soldered them to my customized board. When I try to write mcs file using iMPACT, I see "SPI not found" error message. Also, the chip is recognized as 400A from iMPACT, not 400AN. I'm using ISE 14.1.

I have used 50AN chip  in my previous projects. It worked well, but I have no experience in 400AN. So I'm not familiar with it.

I'm hoping someone can give me some sensible advice on the cause of this.

Looking forward to hearing from you soon.

Thanks.

That board XC3S400AN-5FTG256C is a FPGA board so most likely you need to go to Xilinx website that deals with everything to do with AMD's FPGA hardware.
