DP83TC812S-Q1: 使用 DP83TC812S-Q1时,提示link is not ready

Part Number: DP83TC812S-Q1

TI专家

你好,目前我们在使用 芯片 :DP83TC812S-Q1在全志T517的平台进行调试,系统是:linux - 4.9 目前将调试情况汇总如下:

1, 已在TI官网下载 dp83tc812驱动合入代码中。

2,测量硬件phy芯片VDD VDDIO 供电正常,外部晶体输出clkout 25MHz;

3,通过ifconfig eth0上打开网口后,通过寄存器可以读到phy_id : 0x2000a271,strap 通过寄存器0x45D 读到的值是: 0x00000080,通过log 看到"IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready"

没有使链路工作正常 的信息"eth0: Link is Up - 100Mbps/Full - flow control rx/tx",麻烦帮忙分一下,谢谢

log信息如下:

[ 19.915958] sunxi-gmac gmac0 eth0: eth0: Type(7) PHY ID 2000a271 at 0 IRQ poll (gmac0-0:00)
