Dear Concern,

We are working on NXP T1042 PowerPC Module located on a custom baseboard.

Both module and baseboard are new designs. Here we are facing an issue with RGMII ports issue. (EC1: fm1-mac3 & EC2:fm1-mac4).

We are using DP83867 PHY.

Attached log file.

Need support ASAP.

Thank you

Hi vishwadeep.ns@tridentinfosol.com‌,

Please check the phy address of your dts file. First you will debug with u-boot itself (check u-boot configuration file for phy address provided right or wrong?)

Thanks & Regards,

VinothS.

The request was to provide Device Tree Source (DTS) file.

Please also provide the processor's connection schematics for inspection as searchable PDF and explain which addresses were projected for each PHY.

Please check that you are able to access the RGMII PHY's registers in U-Boot.

In the described case it is convenient to create a Technical Case:

1)    open www.nxp.com
2)    Select "Support" -> "All Support Options"
3)    Click "Go to Tickets"
4)    Log in with your NXP login and password
5)    On the "Group, Create and View your support cases" page press "+ Add a new case" to start the process.
