TMDS64EVM: Testing Ethernet Loopback Using the Loopback Cable

Huynh Nguyen

Part Number: TMDS64EVM

Tool/software:

Hello,

How to modify the current example of ethernet_cpsw_loopback/loopback_phy_end to make it work a little bit further to

the RJ45 ethernet loopback cable (routing the Tx wires back to Rx wires). This will allow me to test from the PHY to the transformer and connector

to make sure the layout is good and no EMI issue.

Thanks,

Huynh

    Hello Huynh Nguyen,

    To which AM64x SDK exactly are you referring to for this ethernet_cpsw_loopback/loopback_phy_end example ? 

    Are you working on the TI TMDS64EVM (as per current thread tag) or on your custom AM64x board (you speak about checking layout for EMI issues) ?

    Are you asking for help with a software or with a hardware modification to adapt the CPSW Eth loopback test to use an  Ethernet loopback cable with RJ45 connector ? 

    Thanks for your clarification  

    Kind Regards,
