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... Jonathan Cormier

Thank you for answer.
(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... Kyungguk Bok

> If you try to write code related to EMIF in CCS, you will need a header file called csl.emifa.h. How can EMIF be performed without the need for a header file? I would like some basic information about EMIF.

Thank you for answer.
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... Kyungguk Bok

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. Jonathan Cormier

Thank you for answer.
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... Kyungguk Bok

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... Gregory Gluszek

KB 08:02 AM Software Development: DSP EMIF Example Code

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... Kyungguk Bok
