Spartan 6 Configuration Solution

Since Xilinx have decided to discontinue the Platform Flash devices but continue with Spartan 6 is their a recommended solution for configuration.

The configuration guide explains that SPI programming is supported but it would appear you are on your own when choosing a device. The iMPACT tools use to support the programming of a connected SPI device. However most of the listed PROMs are obsolete and therefore even if I choose a suitable device I have no method of actually programming it.

Hi @OldXilinxUser 

I believe https://forums.xilinx.com/t5/FPGA-Configuration/SPI-supported-flash-for-Spartan-6-FPGA/m-p/897492/highlight/true#M10092 and https://forums.xilinx.com/t5/FPGA-Configuration/Obsolete-NOR-Flash/td-p/954662 forum post will be helpful for you. 

In short, you can use upgraded version of flash supported by Spartan-6 from same flash manufacture having same command set with SKIP IDCODE workaround. Although you need to characterize and verify it by yourself.

Regards,
Bhushan
