AM335X RGMII双网口异常



电路板硬件是基于BBB改的,软件用的TI官方的SDK6.0(内核版本3.2.0)。
硬件上主要改了双网口(都是RGMII接口),PHY用的AR8033,驱动是从3.11的内核上复制过来改的,可以正常 编译。目前内核改了arch/arm/mach-omap2/board-am335xevm.c中的PINMUX和arch/arm/mach- omap2/devices.c中的PHY_ID。现在测试的现象是两个网口插上网线都会提示PHY:0:01-Link is Up,但 改了IP后都没办法ping通主机(一个网段内的),请问还有哪些地方需要修改或检测的?
