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";

memory@0 {

device_type = "memory";

reg = <0x0 0x1000000>; 如果是32M的sdram，应改成0x2000000

};

palmbus@10000000 {

spi@b00 {

status = "okay";

m25p80@0 {

#address-cells = <1>;

#size-cells = <1>;

compatible = "mx25l6405d"; 此处的mx25l6405d为flash,后面会提到如何得到这个串

reg = <0 0>;

linux,modalias = "m25p80", "mx25l6405d";

spi-max-frequency = <10000000>;

partition@0 {

label = "u-boot";

reg = <0x0 0x30000>;

read-only;

};

partition@30000 {

label = "u-boot-env";

reg = <0x30000 0x10000>;

read-only;

};

factory: partition@40000 {

label = "factory";

reg = <0x40000 0x10000>;

read-only;

};

partition@50000 {

label = "firmware";

reg = <0x50000 0x7b0000>;

};

};

};

};

pinctrl {

state_default: pinctrl0 {

gpio {

ralink,group = "jtag";

ralink,function = "gpio";

};

};

};

ethernet@10100000 {

mtd-mac-address = ;

};

wmac@10180000 {

ralink,mtd-eeprom = ;

};

ehci@101c0000 {

status = "okay";

};

ohci@101c1000 {

status = "okay";

};

gpio-keys-polled {

compatible = "gpio-keys-polled";

#address-cells = <1>;

#size-cells = <0>;

poll-interval = <20>;

wps {

label = "reset";

gpios = ;

linux,code = <0x198>;

};

};

gpio-leds {

compatible = "gpio-leds";

power {

label = "rt5350-evb:red:power";

gpios = ;

};

};

};

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)

[ 0.510000] Creating 4 MTD partitions on "spi32766.0":

[ 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'
