刚买的板子PHY为RTL8201,而SDK里的是RTL8211.刚开始没注意到这个问题,烧录后发现网络不通.需要更改uboot及kernel.现在记录如下:
一: UBOOT
修改 /include/configs/hi3516a.h
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
/*----------------------------------------------------------------------- * network config -----------------------------------------------------------------------*/ ..... #define CONFIG_CMD_MII #define CONFIG_CMD_RMII // justchen增加: RMII RTL8201 #define CONFIG_SYS_FAULT_ECHO_LINK_DOWN 1 /*----------------------------------------------------------------------- * HIETH-GMAC driver -----------------------------------------------------------------------*/ .. /* #define CONFIG_HIGMAC_PHY2_ADDR 2 */ #define CONFIG_HIGMAC_PHY1_INTERFACE_MODE 1 // justchen修改: 0:MII 1:RMII 2:GRMII /* #define CONFIG_HIGMAC_PHY2_INTERFACE_MODE 2 */ ... |
其实在这里还可以把默认IP这些改改,注意phy地址与RMII MII模式需要与原理图对应
修改好后编译 uboot.bin
然后还需要修改excel中的 muxctrl_reg93 项 ,将值改为2. 在uboot模式下应该能顺利连网了
二:内核
在内核menuconfig中找不到rmii rgmii的选项. 不过在http://www.ebaina.com/bbs/thread-7876-1-1.html中有大神提到

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
hieth-gmac phy0 interface mode. | | 1---MII, | | 5---RMII, | | 6---RGMII. | | Symbol: HIGMAC_PHY0_INTERFACE_MODE [=5] | | Type : integer | | Range : [1 6] | | Prompt: hieth-gmac phy0 interface mode | | Defined at drivers/net/ethernet/hieth-gmac/Kconfig:46 | | Depends on: NETDEVICES [=y] && ETHERNET [=y] && HIETH_GMAC [=y] | | Location: | | -> Device Drivers | | -> Network device support (NETDEVICES [=y]) | | -> Ethernet driver support (ETHERNET [=y]) | | -> hieth gmac family network device support (HIETH_GMAC [=y]) |
所以找到 hieth-gmac phy0 interface mode 将默认的6改为5 即RMII模式.收工!
