Hi, I am using ar8031 ethernet chip on imx6q board.
Link up message is displayed on terminal.
but, does not ping.
I used an oscilloscope to measure the signal levels of RGMII_CLK (ENET_REF_CLK) and RGMII_TXC.
RGMII_CLK (ENET_REF_CLK) : 1.4V
RGMII_TXC : 1.2V
I think, The signal level seems too low.
Can I solve this problem by adjusting the impedance on the device tree?
I have already changed the value a few times, but there is no change.
Thank you!!!
