I modified the part you mentioned and changed it to 0x66000080, but it still doesn't work.

Okay, so that should mean your fpga code is fine. Note its a good idea to make sure the fpga_gpio.ko kernel module isn't loaded if you are trying to control it from the DSP. They could fight each ot...

- hello.
I am having a problem controlling GPIO with MityDSP-L138F through DSP and FPGA EMIF communication, so I am leaving a question.

constant CORE_TS_MODULE : integer := 5;

Yup, so you should be able to export gpio 144 and access the gpio

_It's not a bad idea to make sure you can control the gpio from Linux before operating it on your DSP._
I think that's a good thing to say. I think it's a good idea to solve problems one by one.

I'm pretty sure the EMIFA will get configured before fpga_ctrl.ko and fpga_gpio.ko module files are loaded. So they aren't strictly required as long as the fpga is loade... - KB 04:36 AM Software Development: RE: DSP EMIF Example Code

(using MityDSP-L138F Devkit)
When using EMIFA to control the LED by controlling the FPGA's GPIO, I found out that EMIFA is set in the kernel when the fpga_ctrl.ko and fpga_gpio.ko module files are loaded. I also f...

Currently working on MityDSP-L138F.
The kernel is loaded on ARM, and HelloworldDSP and FPGA from Wiki have been converted to .bin files so that they are automatically loaded upon booting.
If you try to write code...

- Could you provide an example of what you are trying? I don't believe you should need any special headers, assuming the kernel is loaded and configured the EMIF bus on the ARM.

The environment I am currently studying is Linux (Ubuntu).

- 답변 감사합니다.
지금 제가 공부하고 있는 환경은 리눅스(우분투)입니다.
(wiki에서 다운 받아 설치한 .ova파일)
code composer studio 7.5.0을 사용하고 있습니다. 이 환경에서 DSP로 EMIF에 관해 코딩하려고하니, csl_emifa.h 파일이 필요하다고 합니다.
.ova에는 EMIF에 관해 코드를 진행하기 어려운 상황입니까?
우선 CSL에 관해 필요한 include파일을 설치하고 첨...

- Hello Kyungguk Bok,
From the FPGA perspective the base_module component handles the EMIF transactions and converts then to an internal bus format so that you can have multiple FPGA components (or Cores as we call them) that sit on th... - hello everyone
I am a first time user of MityDSP-L138. Ultimately, I am studying with the goal of receiving ADC data from FPGA and processing it in DSP.
I solved the problem by running the DSP and ARM Eaxmple on the wiki page and loa...
