VJ 08:29 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: eMMC and bus width 8

Hi Dan
Yes, the preloader and uboot has been rebuild after changing the interface in platform designer. If I change to 4 bit in the dts file everything works fine.
We are using Quartus 17.1.

DV 07:24 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: eMMC and bus width 8

Hello,
We haven't tried interfacing to a 8 bit eMMC with the 5CSx SOM. Just to double check did you rebuild your preloader and u-boot when you made the 4 bit to 8 bit change in platform designer? Also are you able to boot to Linux if ... Daniel Vincelette

VJ 12:36 PM MitySOM-5CSX Altera Cyclone V Software Development: eMMC and bus width 8

Hi
Has anyone managed to interface an eMMC using 8 bit?
According to Cyclone V HPS "MMC Support matrix": https://www.intel.com/content/www/us/en/docs/programmable/683126/21-2/mmc-support-matrix.html 8 bit bus and 50MHz clock is support... V J

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).
(.ova file downloaded and installed from wiki)
I am using code composer studio 7.5.0. When I try to code EMIF with DSP in this environment, it says I nee... Kyungguk Bok

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

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
