- Hi Dmitry,
The REFCLK_GXBL_ signals are AC coupled to the PLL chip, so the common mode
should be less of an issue.
With regards,

- Hi, Dan
I found discrepancy:
In Arria 10 and SI5338 datasheets voltage values are significantly different.
May be this is the reason why I don't see REFCLK_GXBL_... signal in Signal tap after divider?
Br, Dmitry.

- Hi, Mike
I found than dedicated pins i2cemac2 were not configured well.
After fix this I saw the correct status 0x06 on the I2C bus and saw SI5338 is reconfigured.
Thank you.
Br, Dmitry.

- Hi Dmitry,
Have you modified the HPS pin configuration from the reference project?
We are wondering if the I2C bus pins are not configured in the quartus project you are using for the I2C connected to the PLL chips. The chips shou... - DK 03:22 PM Software Development: RE: Replacement UBoot 2014.10 on 2021.04

I will wait.
Additional info.
During the while cycle i2c status is 0x00.

- Hi Dmitry,
I see your request. I am consulting with some engineers here to figure out what is going on.
When I have an answer, I will post.

- Hi, Mike
I found the reason why PLL is not configured.
UBoot did not get access to I2C bus. The bus id busy.
I added debug output to source code and find function in which this arises.

Thank you for help. I has some progress!!!
I was in project folder, but Makefile was absent in it.
I got Makefile from Mitysom project, got UBoot compiled and write it to SDcard.

Try to CD into your software/bootloader directory and just run:
make TGZ=uboot-socfpga.tar.gz SOCFPGA_BOARD_CONFIG=mitysom_a10s_dsc_defconfig
Our example expect that you are using our FPGA reference design, which has a ... - DK 01:08 PM Software Development: RE: Replacement UBoot 2014.10 on 2021.04
- Hi, Mike
Thank you for reply.
I did the instruction https://support.criticallink.com/redmine/projects/mitysom_a10s/wiki/Building_U-Boot_for_MitySOM-A10S
And got error on compilation
How I can correct?
Br, Dmitry. - MW 11:44 AM Software Development: RE: Replacement UBoot 2014.10 on 2021.04
- Hi Dmitry,
mitysom_a10s_dsc_defconfig
Follow these instructions when using Quartus 18.0.

- Hi Dmitry,
I believe the DTS is auto generated for u-boot from the quartus tools. I think the bsp-editor is what generates it.
Dan - DK 04:37 PM Software Development: RE: Replacement UBoot 2014.10 on 2021.04
- Hi, Dan
Thank you for reply.
Can I use DTS as in attachment for "mitysom_a1" branch? I get him from ArrowElectronics.
If not than where I can get right DTS or DTB for UBoot compiling?
Thank you very much in advance.

The ADRV9009 demo was built using quartus 18.0 and using uboot 2014.10. Critical Link has a uboot 2014.10 that supports programming the PLLs the branch is called "mitysom_a10": https://support.criticallink.com/gitweb/?p=u-b... - Hi All

- Hi Dmitry,
You're "After correction.jpg" looks to be correct. Have you also checked if U15 CLK1 behaves the same way?
Can you send me your FPGA project or a simplified version for me to review?
Thanks,

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...

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...
