TMDSCNCD28388D: Question about PHY_CLK

Part Number: TMDSCNCD28388D
Other Parts Discussed in Thread: C2000WARE

Dear team:

c2000ware\C2000Ware_4_01_00_00\libraries\communications\Ethercat\f2838x\examples

When the customer used controlCARD to test this routine, he found that the 25MHz clock source of the PHY was set from GPIO154:

And the customer can connect to the Beckhoff master station during the test routine.

But the schematic of controlCARD shows that the 0 ohm resistor connecting GPIO154 to Px_PHY_CLK is not soldered:

Where does the clock source of PHY_CLK come from?

Best regards,

Green
