rgmii loopback test for imx6q

pravverma — Tue, 08 Dec 2015 15:29:35 GMT

Hi,

We are using i.xm6q based custom board.

We are facing packet loss for size 1k+ consistently.

To debug the issue & verify the driver, I want to enable the loopback as mention in following.

Receive Control Register (ENET_RCR)[LOOP] = 1

But this bit is explained as MII internal loopback, To enable loopback we have to set MII_MODE set to 1 & RMII_MODE set to 0.

Could we use this loopback to test the RGMII driver also?

If not how to test the loopback for RGMII?

Thanks,

Praveen

Internal MII loopback described in this register supposes only MII not RGMII.

I mean we have only MII loopback in i.MX6Q processor.

Sorry for the inconvenience.

Have a great day,

Victor
