各位大牛，这边有两个问题请教下各位：
1、我这边在使用EMAC启动时候无法从网络启动，使用的网络芯片是TLK105，为MII模式，晶振25MHZ，cpu芯片AM3352，cpu晶振24MHz，串口打印信息如下：
U-Boot SPL 2013.01.01 (Sep 29 2014 - 10:41:06)
Could not probe the EEPROM; something fundamentally wrong on the I2C bus.
Could not get board ID.

2、我另一个板子使用的是USB启动，这个可以正常启动kernel并且也可以把内核和文件系统烧录到eMMC，但是调试网络部分的时候，能够识别到TLK105的百兆网，但是无法获取ip，打印如下：
