Serdes Behavior

Hello,

  We have a custom board using SDI with Cyclone 10 GX device.

For unknown reason, we found the Serdes can't locked to external signal after power on/off at about 10%.

We tried download sof once we found the serdes failed,  but the status kept the same.

We check the power sequence and it met the requirement.

How can we clarify this issue.. whether it's power related or others.

Power

    When the issue happened,  we found portion of the design is running well like Nios CPU and memory controller.

    Any comments.
