I'm really not a specialist in FPGA :-)
For several years now I have a microbalze SoC running on a Digilent Spartan
-3 Starter Kit Board with a XC3S200 FPGA. The board acts as the digital con troller of a NMR spectrometer. Since I need more uC memory to update my cod e (only have 16 K in this implementation) I purchase from Diligent another S3SKB with a XC3S1000FT256-4 FPGA that was been sitting at my desk for four years now.
I finally decided to migrate the design from my old board to the new one. T o make sure I knew what to do, I started with one of those MB tutorials fou nd on the web, compile it and download the bit file to the old board using impact. The application run as expected. I then went back to XPS and change d the device size on system->project option, recompiled the design, and aft er downloading, nothing happens. Actually, all leds on the board lit up and stay that way.
So, I guess my questions are:1 - The new board came with a design loaded on the platform PROM. Do I need to change anything to force MB to load from BRAM? 2 - Besides changing the device size on XPS, do I need to change anything e lse on my project.
Any other ideas?
I'm using XPS 7.1 (it works for me !)
