[laufei]

Hello, Freescale

My software codes are based on imx6_platform_sdk_v1.1.0, hardware board is the Sabre SD.

I am running the RGMII AR8031 G-Ethernet Test, but it noe working. see the test log.

Can you help me check the result or rootcause?

Thanks.

Hi fe

probably you did not use loopback cable (or incorrectly soldered)

please refer below

Create a Loopback Plug for an RJ-45 Ethernet Interface - Technical Documentation - Support - Juniper...

Also use latest SDK and recheck that for compillation was used correct board and processor

i.MX 6Series Platform SDK

Hi, chipexpert

Thank you for your reply, I checked the loopback cable which is OK.

And I use the latest SDK, named "imx6_platform_sdk_v1.1.0"

I found that the issued was discussed by imx6q ENET test in platform SDK is not working,

From the discussion, I think that there maybe a bug on this or other issue?

Thanks.

Hi fe

thanks for pointing on that.

Unfortunately seems fix is not available.

I would suggest to run Uboot (it supports AR8031 fine)

and dump i.MX6 ENET registers (with command "mdl"),

then copy them to SDK sources.

Best regards
