Hi

 

I'm Working On LS1021A-IOT board REF board (REV 1), SDK V1.8. My current task is to bring up RGMII interface on LS1021A-IOT board.It uses dspi for managing the RGMII, The RGMII is eTSEC3. But RGMII is never working on my board. I tried to access RGMII register via SPI, but I didn’t get any response from RGMII. Do I need further configuration for setting up SPI as RGMII management interface(In device tree or kernel driver).

 

Thanks In advance
