TE0807 Starterkit reference design with added VCU doesn't work

[michielm]

After using this reference design succesfully:
https://wiki.trenz-electronic.de/display/PD/TE0807+StarterKit
together with this SOM:
https://shop.trenz-electronic.de/en/TE0807-03-7DE21-AZ-MPSoC-Module-with-AMD-Zynq-UltraScale-ZU7EV-1E-4-GByte-DDR4-5.2-x-7.6-cm

I tried to get the VCU working. So i addeded the VCU to the PL, exported a new XSA and imported it into the petalinux project. However strange thing is that the VCU reports an error:
[   26.602120] al5e 80000000.al5e: Mcu didn't start (no ping after startup, is mcu enabled ?)
[   26.602120] al5d 80020000.al5d: Mcu didn't start (no ping after startup, is mcu enabled ?)
[   26.742147] al5e 80000000.al5e: Failed to setup firmware
[   26.758135] al5d 80020000.al5d: Failed to setup firmware

I only get rid of this error by either starting a petalinux project from scratch or replace the TRENZ FSBL by the default Xilinx ZYNQMP FSBL.

But the reason i ask here is that I'm not sure it's really the FSBL. Using a Trenz TE0803 ZU4EV SOM I was able to get it going with the Trenz FSBL.

I also asked Xilinx but they only told me the VCU is very picky on the applied pll_ref_clk:

Can you think of a reason why i have so many troubles to get the VCU going?

Hi

Sometimes clocks may have coupling that can be an issue. So my idea was to turn off some clocks (SATA/USB) generated by the Si5345B clock chip which I don't need. However if open clock builder pro project enclosed in the reference design:

https://shop.trenz-electronic.de/trenzdownloads/Trenz_Electronic/Modules_and_Module_Carriers/5.2x7.6/TE0807/Reference_Design/2022.2/StarterKit/TE0807-StarterKit-vivado_2022.2-build_6_20230817092640.zip

Clock builder tells me the project (Si5345-RevB-0807Project.slabtimeproj) is corrupt....

Apparently clockbuilder 3.0 is able to load the project. As said the latest Silabs clockbuilder 4.11 doesn't work...
