IMX8QXP RMII KSZ8041

Hi,

Currently in RMII mode we are using 25 Mhz crystal mode

The KSZ8041RNL generates the 50MHz RMII REF_CLK and outputs it to the MAC

attached is the block diagram for your reference.

In pin configuration RGMII_TXC should be configured as ENET0_RCLK50M_IN input right?

IMX8QXP_ENET0_RGMII_TXC_CONN_ENET0_RCLK50M_IN 0x06000061

Also let us know the pad settings 0x06000061 is correct

I hope you are doing well.

Your understanding is correct and the pad settings also seem to be correct.

Thanks & Regards,
