前段时间在某宝上买了这个RT5350-EVB ver3.1开发板。近日发现，这些核心板都跟HLK-RM04是一样的。。。。。。
OpenWrt使用的是最新的稳定版Barrier Breaker 14.07，该版本已经支持RT5350
因为该开发板与HLK-RM04相似，所以后面的操作都是仿照它添加的
下载链接：http://download.csdn.net/detail/x901205/8055975
1.创建文件barrier_breaker/target/linux/ramips/rt305x/rt5350evb.mk
define Profile/RT5350EVB NAME:=RT5350-EVB PACKAGES:=\ kmod-usb-core kmod-usb-ohci kmod-usb2 kmod-ledtrig-netdev endef define Profile/RT5350EVB/Description Package set for RT5350-EVB Module endef $(eval $(call Profile,RT5350EVB))
2.添加如下内容到barrier_breaker/target/linux/ramips/image/Makefile：
438行处：
BuildFirmware/RT5350EVB/squashfs=$(call BuildFirmware/Default8M/squashfs,$(1),$(2),$(3),$(4)) define BuildFirmware/RT5350EVB/initramfs $(call BuildFirmware/OF/initramfs,$(1),$(2),$(3),$(4)) #mkhilinkfw -e -i$(call imgname,$(1),$(2))-uImage.bin -o $(call imgname,$(1),$(2))-factory.bin; endef Image/Build/Profile/RT5350EVB=$(call BuildFirmware/RT5350EVB/$(1),$(1),rt5350-evb,RT5350EVB,RT5350-EVB)
607行处：
$(call Image/Build/Profile/RT5350EVB,$(1))
3.新建文件barrier_breaker/target/linux/ramips/dts/RT5350EVB.dts
/dts-v1/;
/include/ "rt5350.dtsi"
/ {
compatible = "RT5350EVB", "ralink,rt5350-soc";
model = "RT5350-EVB";

};
palmbus@10000000 {
spi@b00 {
status = "okay";
m25p80@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "mx25l6405d"; <span style="color:#FF0000;">此处的mx25l6405d为flash,后面会提到如何得到这个串</span>
reg = <0 0>;

};
};
};
pinctrl {

ralink,group = "jtag";
ralink,function = "gpio";
};
};
};
ethernet@10100000 {
mtd-mac-address = <&factory 0x4>;
};
wmac@10180000 {
ralink,mtd-eeprom = <&factory 0>;
};
ehci@101c0000 {

};
ohci@101c1000 {

};
gpio-keys-polled {
compatible = "gpio-keys-polled";
#address-cells = <1>;

wps {

};
};
gpio-leds {
compatible = "gpio-leds";
power {
label = "rt5350-evb:red:power";
gpios = <&gpio0 0 1>;
};
};
};
4.添加以下到barrier_breaker/target/linux/ramips/base-files/etc/diag.sh：67
rt5350-evb) status_led="rt5350-evb:red:power" ;;
5.添加以下到barrier_breaker/target/linux/ramips/base-files/etc/uci-defaults/01_leds：112
rt5350-evb) set_wifi_led "rt2800pci-phy0::radio" ;;
6.添加以下到barrier_breaker/target/linux/ramips/base-files/etc/uci-defaults/02_network：225
rt5350-evb | \
7.添加以下到barrier_breaker/target/linux/ramips/base-files/lib/ramips.sh：157
*"RT5350-EVB") name="rt5350-evb" ;;
8.添加以下到barrier_breaker/target/linux/ramips/base-files/lib/upgrade/platform.sh：55
rt5350-evb | \
9.编译，烧写（建议直接选上luci，免得后面再来做）
只要配置了正确的cpu、flash、sdram，OpenWrt就可以正常的跑起来了。
怎么得到flash串？
在uboot起动的时候会输出硬件信息，OpenWrt启动的时候也会有检测：
[ 0.470000] m25p80 spi32766.0: found mx25l6405d, expected s25fl064k [ 0.490000] m25p80 spi32766.0: mx25l6405d (8192 Kbytes) [ 0.500000] 4 ofpart partitions found on MTD device spi32766.0 [ 0.510000] Creating 4 MTD partitions on "spi32766.0": [ 0.520000] 0x000000000000-0x000000030000 : "u-boot" [ 0.530000] 0x000000030000-0x000000040000 : "u-boot-env" [ 0.550000] 0x000000040000-0x000000050000 : "factory" [ 0.560000] 0x000000050000-0x000000800000 : "firmware" [ 0.580000] 0x000000144de5-0x000000800000 : "rootfs"
其中第一行中，表示检测到的是mx25l6405d，而配置的时候，选用的是s25fl064k；在dts文件中改成mx25l6405d并重新编译即可。
内存的检测：
[ 0.000000] Zone ranges: [ 0.000000] Normal [mem 0x00000000-0x01ffffff] [ 0.000000] Movable zone start for each node [ 0.000000] Early memory node ranges [ 0.000000] node 0: [mem 0x00000000-0x01ffffff]
说明内存是32M
如果内存不正确的话，可能在运行的时候会出现oom-killer错误：

关于pppoe的设置：
在 接口->wan中设置中，使用pppoe协议，输入用户密码即可，如果出现不能成功拨号，获取到ip的话，查看交换机的设置，配成如下即可(特别留心4号端口(wan口))：
也可修改配置文件/etc/config/network中的vlan配置：
config switch option name 'rt305x' option reset '1' option enable_vlan '1' config switch_vlan option device 'rt305x' option vlan '1' option ports '0 1 2 3 6t' config switch_vlan option device 'rt305x' option vlan '2' option ports '4 6t'
