KB 09:50 AM Software Development: RE: I have another question regarding EMIF.

I have additional questions.
I would like to perform EMIF communication only with DSP and FPGA, without ARM.
If you proceed without fpga_ctrl.ko, does EMIF communication proceed without ARM?
DSP informed me
void ReadFromFIFOo... Kyungguk Bok

Thank you for answer.
I'm still a beginner, so my questions may be basic.
If I input o_DBus<= Data in FPGA, will data be transmitted?
As far as I know, EMIF has an address and data, but the example above only has a CS address.

MW 11:22 AM Software Development: RE: I have another question regarding EMIF.

If you have the FPGA portion working by decoding the address to the FIFO using the base_module.vhd file, which generates a read strobe and an enable, etc., then for the DSP all you need to do is create a basic integer pointer and derefer... Michael Williamson

Hi. Can you give an example of what you are trying to do? Your question
isn't making sense to me. Jonathan Cormier

KB 01:24 PM Software Development: I have another question regarding EMIF.

hello
I have another question regarding EMIF.
Currently, we have performed an EMIF communication GPIO example using MDK.
mpGpio = new tcDspFpgaGpio((void*)0x66000280);
From a DSP perspective, we proceeded by entering the phys... Kyungguk Bok
