Spartan 3an Bootloader Question

Hi, I am using a spartan 3an and was wondering if it is possible to store the configuration file in ISF and boot the user application code in external spi flash?  On startup, I want the FPGA to run a small bootloader in ISF and grab the application code in external spi flash and copy it to RAM.  Can this be done since the ISF is already using spi?  Also, I cant perform indirect programming to external spi via iMPACT because of ISF. 

 

Thanks

HV

Re: Spartan 3an Bootloader Question

As I can understand, you will need to programme external SPI Flash connected to Spartan-3AN using IMPACT. There is one problem, IMPACT does not (now?) support indirect programming of external SPI Flash for Spartan-3AN. How to overcome the problem is written here:

I hope this helps you.

Almost 2 years too late, I'm afraid.
