Hi all,


In my Spartan6 board design, I want to use a Xilinx platform flash to
configure it.
My Spartan6 is a XC6SLX150 (32.2Mbits configuration memory) and the
flash is a XCF32P (32Mbits).
I' ve several questions :

Is the flash big enough or should I have to use decompression option?
How to program the flash with a microcontroller, is it possible with
serial or parallele interface, with jtag interface?

what other solution would you choose for the memory configuration and
which can be updated with a microcontroller?


Thank you

I don't know the Spartan 6 family per se, but my application is using
a Spartan 3A and I use the SPI Flash configuration option. Quite nice
and easy to update from a microcontroller, or even the FPGA itself if
you wanted (I do my updates over a radio module).
