自编译Tl-wdr5600-v1的OpenWrt固件：wdr5600-v1在OpenWrt官网上并没有可用的固件供下载，所以通常我们都是利用wdr6500-v2模板，通过修改相应文件来编译产生适用于wdr5600-v1的固件。当然你也可以做得更彻底，跟wdr7400-v2一样通过添加新设备的方式直接生成像官方固件一样正式的固件。受篇幅所限，本文只介绍wdr5600-v1与wdr6500-v2在编译之前需要知道的不同之处，其它过程像wdr5600-v1刷breed、自编译过程、添加新设备等过程都统统略去。
一、保证无线5G正常工作
由于wdr6500-v2的5G无线采用的是qca9882芯片，而wdr5600-v1采用的则是qca9887芯片，所以必须采用不同的驱动程序，否则无线5G不能用。
修改 ~/target/linux/ar71xx/image/generic-tp-link.mk 中wdr6500-v2的5G无线驱动程序：
define Device/tl-wdr6500-v2 $(Device/tplink-8mlzma) DEVICE_TITLE := TP-LINK TL-WDR6500 v2 DEVICE_PACKAGES := kmod-usb-core kmod-usb2 kmod-usb-ledtrig-usbport kmod-ath10k-ct ath10k-firmware-qca988x-ct KERNEL := kernel-bin | patch-cmdline | lzma | uImage lzma KERNEL_INITRAMFS := kernel-bin | patch-cmdline | lzma | uImage lzma | tplink-v1-header BOARDNAME := TL-WDR6500-v2 DEVICE_PROFILE := TLWDR6500V2 TPLINK_HWID := 0x65000002 TPLINK_HEADER_VERSION := 2 endef TARGET_DEVICES += tl-wdr6500-v2
将 kmod-ath10k-ct 修改为 kmod-ath10k；将 ath10k-firmware-qca988x-ct 修改为 ath10k-firmware-qca9887
define Device/tl-wdr6500-v2 $(Device/tplink-8mlzma) DEVICE_TITLE := TP-LINK TL-WDR6500 v2 DEVICE_PACKAGES := kmod-usb-core kmod-usb2 kmod-usb-ledtrig-usbport kmod-ath10k ath10k-firmware-qca9887 KERNEL := kernel-bin | patch-cmdline | lzma | uImage lzma KERNEL_INITRAMFS := kernel-bin | patch-cmdline | lzma | uImage lzma | tplink-v1-header BOARDNAME := TL-WDR6500-v2 DEVICE_PROFILE := TLWDR6500V2 TPLINK_HWID := 0x65000002 TPLINK_HEADER_VERSION := 2 endef TARGET_DEVICES += tl-wdr6500-v2
二、保证网络及系统指示灯工作正常
1、修改 ~/target/linux/ar71xx/files/arch/mips/ath79/mach-tl-wdr6500-v2.c 文件中指示灯的配置
#define TL_WDR6500_V2_GPIO_LED_SYS 21 #define TL_WDR6500_V2_GPIO_LED_WAN 18 #define TL_WDR6500_V2_GPIO_LED_LAN1 17 #define TL_WDR6500_V2_GPIO_LED_LAN2 16 #define TL_WDR6500_V2_GPIO_LED_LAN3 15 #define TL_WDR6500_V2_GPIO_LED_LAN4 14
{
.name = "tp-link:white:system",
.gpio = TL_WDR6500_V2_GPIO_LED_SYS,
.active_low = 0,
},
先将WAN口指示灯GPIO从 18 改为 19
#define TL_WDR6500_V2_GPIO_LED_SYS 21 #define TL_WDR6500_V2_GPIO_LED_WAN 19 #define TL_WDR6500_V2_GPIO_LED_LAN1 17 #define TL_WDR6500_V2_GPIO_LED_LAN2 16 #define TL_WDR6500_V2_GPIO_LED_LAN3 15 #define TL_WDR6500_V2_GPIO_LED_LAN4 14
再将系统指示灯从高电平点亮修改为低电平点亮
{
.name = "tp-link:white:system",
.gpio = TL_WDR6500_V2_GPIO_LED_SYS,
.active_low = 1,
},
2、修改~/target/linux/ar71xx/base-files/etc/board.d/01_leds 文件中WAN口交换机switch的名称
tl-wdr6500-v2|\
tl-wr741nd)
ucidef_set_led_netdev "wan" "WAN" "tp-link:green:wan" "eth1"
ucidef_set_led_switch "lan1" "LAN1" "tp-link:green:lan1" "switch0" "0x02"
ucidef_set_led_switch "lan2" "LAN2" "tp-link:green:lan2" "switch0" "0x04"
ucidef_set_led_switch "lan3" "LAN3" "tp-link:green:lan3" "switch0" "0x08"
ucidef_set_led_switch "lan4" "LAN4" "tp-link:green:lan4" "switch0" "0x10"
修改为
tl-wdr6500-v2|\
tl-wr741nd)
ucidef_set_led_netdev "wan" "WAN" "tp-link:green:wan" "eth0"
ucidef_set_led_switch "lan1" "LAN1" "tp-link:green:lan1" "switch0" "0x02"
ucidef_set_led_switch "lan2" "LAN2" "tp-link:green:lan2" "switch0" "0x04"
ucidef_set_led_switch "lan3" "LAN3" "tp-link:green:lan3" "switch0" "0x08"
ucidef_set_led_switch "lan4" "LAN4" "tp-link:green:lan4" "switch0" "0x10"
三、解决wan口卡死问题
网络上有人在说wdr5600-v1路由器按wdr6500-v2自编译固件运行后，会出现wan口卡死现象，自己测试时并未发现有此问题，所以下面的解决方法仅做为备选方案讨论。
修改 ~/target/linux/ar71xx/files/arch/mips/ath79/dev-eth.c 文件如下内容：
case ATH79_SOC_QCA956X:
if (id == 0) {
pdata->reset_bit = QCA955X_RESET_GE0_MAC |
QCA955X_RESET_GE0_MDIO;
if (pdata->phy_if_mode == PHY_INTERFACE_MODE_SGMII)
pdata->set_speed = qca956x_set_speed_sgmii;
else
pdata->set_speed = ar934x_set_speed_ge0;
pdata->disable_inline_checksum_engine = 1;
修改为
case ATH79_SOC_QCA956X:
if (id == 0) {
pdata->reset_bit = QCA955X_RESET_GE0_MAC |
QCA955X_RESET_GE0_MDIO;
if (pdata->phy_if_mode == PHY_INTERFACE_MODE_SGMII)
pdata->set_speed = qca956x_set_speed_sgmii;
else
pdata->set_speed = ath79_set_speed_dummy;
pdata->disable_inline_checksum_engine = 1;
四、自编译Tl-wdr5600-v1的OpenWrt固件
wdr5600-v1以添加新设备方式产生的OpenWrt19.07.7版本固件，我已经编译完成：openwrt-ar71xx-generic-tl-wdr5600-v1-squashfs-factory.bin，目前刷入路由器后运行一切正常：
