KCU105 FCM board

Hello;

I am working on test multiple FMC on the KCU105.

I have a simple design where I use a Microblaze MCS with one IO interface and one UART interface + traffic generator on PCIe.

I use one FMC board from one provider and it works fine (UART sends message I expect and I see FMC HPC VADJ is 1.8V)

With another FMC HPC from another provider, i notice VADJ was not driven so I drive it at 1.8V (as expected) and use the same design. PCIe is linked up and traffic starts but I receive on UART unreadable and strange characters.

Is there any possibility that changing VADJ on FMC HPC with Xilinx UART tool has an impact on UART?

Thanks
