6678 EMIF Simple Project Request

Hi Raja 

You are right but EMIF is an interface better than GPIO for transferring data. In some project maybe users don't want to use it for memory devices. It will be better if  the users can use your simple projects for transferring data. 

Thank you.

Hi Titusrathinaraj

Thanks for your answer but I tried it before and this way has a very low rate(~500KSPS). I want use EMIF for sending data from DSP to FPGA and I think I had to use FPGA like a memory. Is it right? If I want send data with address from DSP, May I use EDMA and lld libraries or not? Do you have simple project for doing this?Do you know how can I add lld libraries to the project?

Thank you really. Your good helps is always effective.

I also would like to add the following code.
EDMA3 based NAND EMIFA code.
C:\ti\OMAPL138_StarterWare_1_10_04_01\examples\lcdkOMAPL138\nand\nandDma.c

Its bare-metal code for OMAPL138 Soc (ARM+DSP), you can also use this as reference for EMIFA DMA.

When you have to send data to FPGA, then you should set EDMA source address as "CS address space" and EDMA destination address is FPGA.
When you have to receive data from FPGA, then you should set EDMA source address as FPGA and EDMA destination address is "CS address space".

Thanks Titu

I didn't work with EMIF and EDMA before. Let me work on the codes which you said and if I face with a problem, I ask you later. Thanks for your good helps.
