About the function of the FEC driver of Linux BSP for i.MX6

[yuuki]

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

<Question>
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?

Hi Yuuki

for internal loopback nxp fec driver please refer to

internal loopback test for freescale fec driver on i.MX6 platform 

As KSZ8091RNA is not used in nxp bsps (AR8031 is used on i.MX6DL Sabre board),

I am afraid such loop back function for that etnernet phy is not available.

Best regards
igor
