请问是怎么修复的呢,千兆不可用的情况
Translated by Google:
Use KSZ9031 IC, Ethernet can not use the 1000M Lan
We are using KSZ9031 scenario, if set to 10M / 100M no problem, but if set to 1000M, you can not connect.
Router supports the 1000M.

Hi Guo
suggest to check Table 62. RGMII Signal Switching Specifications IMX6DQCEC
and configure KSZ9031 registers if necessary, like
MMD Address 2h Register 5h - RGMII RX Data Pad Skew
MMD Address 2h Register 6h - RGMII TX Data Pad Skew
MMD Address 2h Register 8h - RGMII Clock Pad Skew
Note, for i.MX6 ENET there is no control on-chip to adjust the delay between
these signals. A delay would need to be implemented at the board level.
Best regards
igor

Hi :
It works now,thanks!
But there is another problem. As we know,IMX6DL ethernet's max speed is 400M,but we can only reach 200M,is there other registers we should adjust?
Thank you!
Regards!
