Hi Atef,
It sounds like based on your findings the SOM module is the issue. It looks like you may have tried to reply to this post via email, which I do not think works for attachments. Can you either reply again and type the serial n... Mike Fiorenza

Hello Critical Link Support,
I’m evaluating a MitySOM-5CSX module (part number 5CSX-H6-42A-RI) and I’m trying to run a test bitstream on the Cyclone V FPGA. I used the SD-card image from your wiki for this module:

John,
For some background, we have a single Quartus reference design project we have setup for the Cyclone V platform. In order to make it easier for end users, we generate this project for every variant of the platform we have and th... Mike Fiorenza

Hi John,
I appreciate all the info, no need to be sorry whatsoever! I'll go ahead and try and answer your questions and concerns below.

I am using:
Quartus prime 23.1
Ubuntu 24.04.2 LTS ( I noted that this was tested on Ubuntu 22.04...)

Ok, Thanks, I'll look into it.
Just so you know, I am quite the novice with this, so, I ask that you please be patient with me if I ask very basic questions. John Iannuzzi

Hi John,
On the main wiki landing page, https://support.criticallink.com/redmine/projects/mityarm-5cs/wiki, there are links for full SD pre-built SD cards (which include images of the reference filesystems) as well as a tar-ball of th... Michael Williamson

Hi Seth,
As mentioned, I have been able to build uboot. I am now studying the steps to build the file system with Yocto. It appears that there a quite a few steps here and, as usual, with Linux, opens the flood gates for mistakes.

Hi Seth,
Thanks, I got u-boot to build. At this point, I have a basic question: If I continue to follow thru the guide for Quartus 23.1, going thru all the steps and build the SD card, what will I have?, i.e. At the end of all this, w... John Iannuzzi
