- John,
Taking a look at your output it appears like you successfully recompiled the SPL and UBOOT. The differences you are noticing are due to the SD card provided on the development kit having an older release of the software on it. Y... - JI 02:19 AM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX
- Hi, so I was able to make uboot and an sd card image. I took the image and loaded it to a blank sd card and powered up the board. I stopped it at the autoboot countdown.
Then I swapped out the sd card to the one that was provided in t...

- Hi Mike,
Thanks for your quick reply.
Here’s what I’ve tried and what I’m seeing:
Reseated the SOM in the DIMM connector → same behavior as before.
Swapped SOMs between kits → when I install the good SOM into the known-problematic... - JI 12:32 AM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX

Thanks. Understood.

- 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... - AF 03:41 PM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: MitySOM-5CSX (5CSX-H6-42A-RI) stops at “Deasserting all peripheral resets” — request for guidance

Thank you for the thorough debug details.

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...

- SL 07:30 PM MitySBC-Agilex5 FPGA Development: RE: MitySOM-A5E PCIe HIP configuration qudstion
- Yes, agreed. It would be a good upgrade path without jumping the SOC family.
- MW 07:05 PM MitySBC-Agilex5 FPGA Development: RE: MitySOM-A5E PCIe HIP configuration qudstion
- Hi Sung,
With a higher speedgrade option, you can get PCIe x4 gen 4 if bandwidth is a concern and the other end point / root port supports it.
With regards,
Mike - SL 06:39 PM MitySBC-Agilex5 FPGA Development: RE: MitySOM-A5E PCIe HIP configuration qudstion
- Thank you again for the prompt response. PCIe x4 gen 3 (4GB/s bus limit) should be sufficient for this generation of products.
- MF 05:11 PM MitySBC-Agilex5 FPGA Development: RE: MitySOM-A5E PCIe HIP configuration qudstion
- Sung,
All of our current Agilex 5 platforms are E-Series, Device Group B devices. Therefore, they only support up to PCIe x4 configurations (not x8). You need a D-series device to support x8.
- Mike - In the MitySOM-A5E datasheet, "up to six x4 PCIe 4.0 hard IP blocks" are supported.
Can some of the PCIe be configured as x8 (three x8 instead of six x4, for example)?

Just checking in on this, were you able to find supply to meet your needs?
Is your board already designed, or can you work with one of the suggested alternates?
Finally, does your design use the Hirose DF40 co...

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.

I have not checked for stock. - Hi,
Please suggest any substitutes for "JAE MM70-314B1-2-R300: card edge receptacle" as this part is out of stock in Digikey and Mouser for longer time.
