Hi,

 

I develop a board based on IMX8MM.

Board is var-som-mx8m-mini.

 

This board is connected to intel ethernet controller i210-AT chip.

then, this chip is connected to PCIE#A_REFCLK100M_N, PCIE#A_REFCLK100M_P.

 

But, I can not use this signal. clock output of this pin is nothing.

How to use a reference clock output for PCIE?

Is this possible to use?

 

Thanks.
