MinimigTg68 in Xilinx FPGA's   Message List

Re: [minimigtg68] Re: MinimigTg68 in Xilinx FPGA's

I tried that a couple of weeks ago, but did not get the expected result. I've only tried it in a Basic test but I had problems getting the lm32 to run on my board.
But I'm both new to DDR-controllers and to the lm32-project so maybe I done something wrong.. I think I'll try it again. I both need it for a seperate hobby-project and it would be GREAT fun to get the TG68-minimig running on the 1600E!

hi,

I am following this thread...

You will find a sopc project using the controller here : https://roulette.das-labor.org/bzrtrac/wiki/soc-lm32

You are correct! It is DDR-memory and the 1600 is a "bigger brother"
of the more common 3E-Starter Kit with its 500K-device.

Thank you for the tip about the DDR-controller. I've seen it but I
would really like a good example of it in use.. Have you seen some?
I'm used to working with SRAM so if it only could be just as simple..

Best Regards
Magnus
