Hi all, I'm trying to load the .mcs file into a SPI FLASH PROMs(M25P40) using the Xilinx Platform Cable USB II. The problem is, I was able to load the .bit file into FPGA but I can't load .mcs file into SPI FLASH. there is always error message:

Could you please help me to solve this? Thanks.

hi zhgwork,

the issue is IDCODE check failure.

'1': IDCODE is '00' (in hex).
'1': ID Check failed.

The IDCODE iMPACT reads from SPI is 00, which means the MISO is always low.

you can probe the pin with an oscilloscope and check to see if the MISO toggles when you perform programming operations.

Thanks. borisq

Yes. The MISO signal is always low. But the MOSI is always HIGH.

Addationally, the CSO and CCLK signals is corrected.

I review your schematic.

I see you connect CMPMOSI to the SPI.

you should use MOSI, not CMPMOSI.

Hi 

had the same problem , turned out that the wrong CS* was connected. (CSI_B_0 instead of FCS_B)
