Dear all,


We use i.MX6DL by our system.
OS is Linux L3.0.53 (Based on NXP BSP)

We have a question about FEC driver included in L3 .0.53 BSP


We want to use Loop back function of the Etnernet PHY.
Is Loop back function included in FEC driver?

KSZ8091RNA is used as Ethernet PHY.

Please refer to section "3.7.1 LOCAL (DIGITAL) LOOPBACK" of the attached file.

We want to confirm whether transmission data match with reception data by using this function.


May I have advice?
