I returned to start Mitysom project downloaded from git.
After first compilation I see inconsistency between Pin Planner and Assignments from one side and results in Input Pins (Fitter report) on another side. You can see all...

- Hi Dmitry,
Your pin out and clock project look to be correct. If you're seeing clocks on the output of U15 then I would say it's programmed correctly. To double check that the FPGA receives it can you route one of the clocks to an FP...

- Hi
You are right. My board is rev 4.
I changed the U15 configuration and currently I use CLK0 (pins R24/R23) and CLK1 (pins AB15/AA16).
But result is the same ((
I see signals on the pins of SI5338, but don't see the signals in sig...

The revision is at the end of the 80-# number of the white tag. For example, 80-001124RC-*4*A is a rev 4 of the 80-001124 part number.
My recommendation is the following:

- Hi
I have rev 9 board and working in accordance with datasheet pointed by you.
You can make sure in that by screenshots attached by me.
Best regards.

- Hi Dmitry,
It looks like you are using the pinout from the rev 8 of our SOM but I believe you have an earlier rev of the SOM.
Your SOMs should follow the clocking that is in our datasheet (Figure 2).

Thank you for the reply.
I added proposed assignments.
I recreated the differential signals on pins. Quartus automatically added paired signals with '(n)' in the end of names.

Do you have differential terminations enabled for these signals? If not that might be the issue. The syntax for adding these to qsf looks like the following: - DK 05:11 PM MitySOM-A10S Altera Arria 10 Software Development: RE: Mitysom a10s does not start under U-Boot 2021.04

SI5338 is working correct, I see right frequencies on output pins (CLK0A, CLK0B, CLK2A, CLK2B) of chip U15.
But FPGA project does not receive these signals.

I had edited my previous post to correct. Yes it is:

The 80-001317RH-5_SCH_RevA.PDF should properly connect the USB-3. You can assume it is OK.

On P29 and P31 of the DataSheet.
You find "Error! Reference source not found."
Please update document.

Our application is MitySOM-5CSx based. We are trying to use FVP or QEMU for simulation during firmware development.
I have been trying to get the ARM FVP with AC5 to work but no success so far. How can I achieve this?
