Subject: Re: [openrisc] Quartus & OR1200
Dear Christian,
sounds like a pin allocation problem of some sort.
maybe you should check out the quartus help file for some explanation.
press with your right-mouse button on the error message and press help.
What I'm about to say may offend you and seem arrogant of me, therefor
I'm apolagize, Christian, but I'm having the impression that you are a
FPGA-digital logic beginner. Damjan Lampret (project maintainer of OR)
already warned people before that OpenRISC isn't a one-click solution!
You should really have some experience to implement not only OpenRISC,
but any softcore processor. I share his opinion.
Therefor I suggest 2 things:
1) get a course on FPGA's and verilog/VHDL. If you already did this: try
to first build an asynchronous circuit and then a synchronous
state-machine. (simulate and also implement it in real life on a FPGA
development board and try to blink some leds on it)
2) Then start with 'easy' softcore processors (Nios and Microblaze),
just to get some experience in the softcore based embedded systems...
Best of luck,
sincerely,
Dries
