AM335X Ethnet问题

使用AM335X，通过MII外接Marvell的swtich芯片，单网口

问题1:使用mdio读PHY的寄存器

mdio r 1.1
Reading from bus cpsw
PHY at address 0:
1.1 – 0x201

读到的值不对，而且每次读到的值都不一样

问题2：使用mii info 打印PHY信息

mii infoPHY 0x00: OUI = 0x100010, Model = 0x00, Rev = 0x00, 10baseT, HDX
PHY 0x01: OUI = 0x0000, Model = 0x00, Rev = 0x00, 10baseT, HDX
PHY 0x02: OUI = 0x0000, Model = 0x00, Rev = 0x00, 10baseT, HDX
PHY 0x03: OUI = 0x0000, Model = 0x00, Rev = 0x00, 10baseT, HDX
PHY 0x04: OUI = 0x3000, Model = 0x0C, Rev = 0x00, 10baseT, HDX
PHY 0x05: OUI = 0x3000, Model = 0x0C, Rev = 0x00, 10baseT, HDX
PHY 0x06: OUI = 0x3000, Model = 0x0C, Rev = 0x00, 10baseT, HDX
PHY 0x07: OUI = 0x302030, Model = 0x08, Rev = 0x00, 10baseT, HDX
PHY 0x10: OUI = 0x27C002, Model = 0x19, Rev = 0x02, 10baseT, HDX
PHY 0x11: OUI = 0x27C002, Model = 0x19, Rev = 0x02, 10baseT, HDX
PHY 0x12: OUI = 0x27C002, Model = 0x19, Rev = 0x02, 10baseT, HDX
PHY 0x13: OUI = 0x27C002, Model = 0x19, Rev = 0x02, 10baseT, HDX
PHY 0x14: OUI = 0x27C002, Model = 0x19, Rev = 0x02, 10baseT, HDX
PHY 0x15: OUI = 0x27C002, Model = 0x19, Rev = 0x02, 10baseT, HDX
PHY 0x16: OUI = 0x27C002, Model = 0x19, Rev = 0x02, 10baseT, HDX
PHY 0x17: OUI = 0x27C002, Model = 0x19, Rev = 0x02, 10baseT, HDX
PHY 0x18: OUI = 0x27C002, Model = 0x19, Rev = 0x02, 10baseT, HDX
PHY 0x19: OUI = 0x27C002, Model = 0x19, Rev = 0x02, 10baseT, HDX
PHY 0x1A: OUI = 0x27C002, Model = 0x19, Rev = 0x02, 10baseT, HDX
PHY 0x1B: OUI = 0x0000, Model = 0x00, Rev = 0x00, 10baseT, HDX

打出一堆，switch芯片有8个PHY,只用了6个，而且每个PHY的信息每次都在变化

第一次调试网络，论坛有没有大神分析下是什么原因，顺便指导一下，小弟不胜感谢
