Hi,
I'm trying to bring-up DP83TG720S in Linux, RGMII loopback mode now worked well. So next, I tried to link up DP83TG720S to a switch device. In the DP83TG720S driver, I forced it to work in 1000Mbps/Full Duplex mode. But value of BMSR register is always 0x141 showing "Link down" status and "Energy det change interrupt"( bit 14 0x12 register) raises all time. I don't know where is the problem. Can anyone help me to debug the issue.
Thanks.
