Hi,
we are trying to use ENET1 and ENET_QOS on IMX8MP.
For ENET1 the REF_CLOCK is listed in the signal mapping as GPIO1_IO00.
When I now look for the signal mapping for ENET_QOS there is no such pin defined.
Do I have to share the ENET1 clock signal using a clock buffer or are there any other pins use?
ENET1 and ENET_QOS should run in RGMII mode.
Any hints where to get this signal from?
Kind regards.

Hi @Jerry_H
For EQOS CLOCK mapping, you can choose EXT_CLK_4 if you want to use external clock.
But in evk dtsi, eqos is using SYS_PLL1 and SYS_PLL2.
There is no clock name like ENET_QOS_REF_XXX, maybe the ENET_QOS_TIMER_CLK_ROOT is your need.
