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?
