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?
