OpenWrt玩家新玩具：京东新路由2已被破
新路由2 是由 京东发布的一款新产品。型号为NEWIFI D1。配置有MT7621A处理器，双核四线程。DDR3 256MB大容量内存。32MB闪存。2.4G+5G的无线解决方案。还有USB3.0接口。配置很高，很适合爱好者来HACK
但是因为新品很多资料没发布。
我朋友自己尝试了一下最新版的OPENWRT 15.05是可以支持的。还存在两个主要BUG：
1、启动系统的时候如果网线是插着的状态网口会死掉。无法工作。必须启动机器不插网线，有时候偶尔开一段时间还恢复正常。
2、官方1505目前不支持他的2.4G无线网卡，所以系统只有5G无线网络。
反正我们是搞不定了。看看谁能搞定吧。
编译方法：
使用官方openwrt1505版。然后在target/linux/ramips/dts/下生成NEWIFID1.dts文件，内容如下：/dts-v1/;
/include/ "mt7621.dtsi"
/ {
compatible = "mediatek,mt7621-eval-board", "mediatek,mt7621-soc";
model = "D1";
memory@0 {
device_type = "memory";
reg = <0x0 0x10000000>;
};
chosen {
bootargs = "console=ttyS0,115200";
};
palmbus@1E000000 {
gpio@600 {
gpio0: bank@0 {
status = "okay";
};
gpio1: bank@1 {
status = "okay";
};
};
spi@b00 {
status = "okay";
m25p80@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "mx25l25635e";
reg = <0 0>;
linux,modalias = "m25p80";
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>;
};
partition@50000 {
label = "firmware";
reg = <0x50000 0xfb0000>;
};
};
};
};
pcie@1e140000 {
status = "okay";
pcie0 {
mt76@0,0 {
reg = <0x0000 0 0 0 0>;
device_type = "pci";
mediatek,mtd-eeprom = <&factory 0x8000>;
mediatek,2ghz = <0>;
};
};
pcie1 {
mt76@1,0 {
reg = <0x0000 0 0 0 0>;
device_type = "pci";
mediatek,mtd-eeprom = <&factory 0x0000>;
mediatek,5ghz = <0>;
};
};
};
ethernet@1e100000 {
mtd-mac-address = <&factory 0xe000>;
};
gpio_export {
compatible = "gpio-export";
#size-cells = <0>;
usb20-power {
gpio-export,name = "usb20-power";
gpio-export,output = <1>;
gpios = <&gpio0 9 1>;
};
usb30-power {
gpio-export,name = "usb30-power";
gpio-export,output = <1>;
gpios = <&gpio0 11 1>;
};
};
gpio-leds {
compatible = "gpio-leds";
power {
label = "d1:green:power";
gpios = <&gpio0 14 0>;
};
sys1 {
label = "d1:green:sys1";
gpios = <&gpio0 16 1>;
};
sys2 {
label = "d1:green:sys2";
gpios = <&gpio0 13 1>;
};
};
gpio-keys-polled {
compatible = "gpio-keys-polled";
#address-cells = <1>;
#size-cells = <0>;
poll-interval = <20>;
reset {
label = "reset";
gpios = <&gpio0 15 1>;
linux,code = <0x198>;
};
};
pinctrl {
state_default: pinctrl0 {
gpio {
ralink,group = "rgmii2", "jtag", "wdt rst", "mdio", "sdhci", "uart2", "uart3";
ralink,function = "gpio";
};
};
};
};
然后编辑target/linux/ramips/image/Makefile
在ifeq ($(SUBTARGET),mt7621) 下面的TARGET_DEVICES值中增加d1
然后，再下面找个地方写一个参数define Device/d1
DTS := D1
IMAGE_SIZE := $(ralink_default_fw_size_32M)
endef编辑target/linux/ramips/base-files/etc/board.d/02_network
在firewrt | \下面增加d1 | \
有以上的基本就够了。然后就正常编译OPENWRT的流程了。可以测试看看了！！
