I'm using imx6dl processor in which mac is connected to phy(ksz9031) in RGMII mode. I'm facing an issue with hardware time stamping.
I want to feed the125 MHz clock to ENET_REF_CLK internally through GPIO_16 .
As per the Table 2-9. Gigabit Ethernet Recommendations from the below pdf
I have configured GPR1 = 1 to select internal reference clock, through which I'm getting 50MHz clock on to GPIO_16.
Now i want to route the 50MHz clock from GPIO_16 to ENET_REF_CLK internally.
Is it necessary to connect ENET_REF_CLK(V22) pin to GPIO_16(R2) pin externally?
Configuring GPIO_16 SION = 1 is enough to route internally?
