Problems about EMAC

Other Parts Discussed in Thread: CCSTUDIO

Hi, guys! I'm testing EMAC on C6474 by using the test example in C:\CCStudio_v3.3\boards\evmc6474_v1\tests\emac, it says in the program that "EMAC tests to send data to external loopback cable", should I just connect C6474 EVM with PC by cable?

This requires an external loopback cable as per the description. That is not connecting it with PC, but looping back externally.

Best Regards,

Chad

Thanks for your answer! What is a loopback cable because there is only one RJ-45 on C6474?

I'm not sure how exactly to describe it other than it loopsback the Rx to Tx and Tx to Rx. You can google RJ45 Loopback Cable and you'll find a lot of info on what one is, and how they connected, and you can purchase one if you don't want to make one.

Best Regards,

Chad
