修改phy寄存器
phy ge0 0x1f 0x3 //打开访问权限
phy ge0 0x10 0x02c2 //更改0x10寄存器的值为0x02c2
2.查看pci寄存器的值
(1)g pcic 0x00
查看pci的地址为0x00寄存器的值
(2)dump pcic
查看所有pcic寄存器的值
3.查看CMICC寄存器的值
(1)g pcim 0x0130
查看地址为0x0130的寄存器值//0x0130寄存器的名称为CMIC_I2C_SLAVE_XADDR，也可以使用：g pcim CMIC_I2C_SLAVE_XADDR
(2)dump pcim
查看所有pcim寄存器的值
4.查看soc寄存器的值
(1)dump soc
查看所有的soc寄存器的值
(2)g soc XTHOL
查看XTHOL寄存器的值，其中soc可以去掉,soc寄存器不支持"g soc 寄存器地址“的方式查看寄存器的值

PRBS配置
xe8,xe9自环
phy prbs xe8-xe9 set mode=hc p=3
phy prbs xe8-xe9 get mode=hc
ge5与对端设备相连
phy prbs ge5 set mode=hc p=3 //配置prbs,配置后会发送报文，需对端也配置prbs
phy prbs ge5 get mode=hc //接收prbs
phy prbs hg0 clear mode=hc //清楚
查询bcm Shell命令函数调用过程
debug bcm api;phy prbs hg0 get mode=hc;debug bcm api
#打开调试
debugm bcm api
#关闭调试
debugm bcm -api
xgxs16g.c
配置prbs入口函数：_phy_diag_prbs
#bcm53262 fe端口配置成100M-FX模式：
1. Write 0x2100 to PHY register 0x00-0x01 (SPI offset address): to put the PHY in 100M, full duplex mode with auto-negotiation disabled.
2. Write 0x0220 to PHY register 0x20-0x21 : to bypass the scrambler/descrambler block. Bit 9 bypasses the scrambler and descrambler blocks. Bit 5 enables the 100 BASE-FX Far-End-Fault function
3. Write 0x0020 to PHY register 0x2E-0x2F : to change MLT-3 code to two-level binary.
4. Write 0x008B to PHY register 0x3E-0x3F: setting bit 7 to enable the shadow register.
5.Write 0x0200 to PHY register 0x32-0x33 : to enable the special signal detection block.
6. Write 0x0084 to PHY register 0x3A-0x3B : to configure the transmit amplitude to 1v pk-pk.
7. Write 0x000B to PHY register 0x3E-0x3F: to exit the shadow register mode.
具体配置方法如下：
1.phy fe8 0x00 0x2100
2.phy fe8 0x10 0x0220
3.phy fe8 0x17 0x0020
