ETHERNET C6748 is not able to receive

Axay Rana

Hello,

I am using custom board similar to the LCDKC6748 and i am trying Ethernet communications.

I am able to have alive and link to the PHY LAN8710A by checking the mdio and emac register bunch.

I am able to transmit the data by writing the transmission descriptor and able to see the interrupt on channel TXINTSTATRAW.

Now, i placed phy in the loop-back mode to verify the receive channel.

I am seeing nothing in RXINTSTATRAW and even on RXGOODFRAMES registers.

Any clues?

Dear Axay,
You should get some value in both RXINTSTATRAW and RXGOODFRAMES registers.
I've sent some EMAC RMII loopback code in private chat, please try that let me know.

Thanks Titus.
I have got the code and my code was similar to that one almost.
My code was working already however bad PHY driver ic was the problem and replacement of it has solved the issue.
Thanks for the guideline though!
