am335x with marvell 88e6061 6 port switch

zai Jonathan

Dear guys:

i using mavell 88e6061 6port switch in am335x 05.06.00.00 (for linux 3.2.0). i have some question.

1. I have debug icplus ip101a, which has the phy_id 0x11. But in marvell switch where is phy address??? port number ????

2. Should i modify the am33xx_cpsw_init in devices.c ? HOW ??

3. I set P5_MODE internal pull-up?

这个要看你的mavell芯片里那里可以设置phy id吧？

Linux有没有自带的交换芯片驱动，可以做参考

1.周建，首先要确定一下，这个驱动官方给的驱动linux的驱动无法使用是跨平台的那种。

2.我想问一下CPSW omap_device_build 这行是不是需要把 “davinci_mdio” 换成 “dsa“ ? 我换了一下产生如下错误,可以确定的一点是DSA已经启动了，但是可能那块出错需要调整一下。请问你们那边有没有遇到过类似的问题。
