From 0c24b363a69d1445a280e41e5c33675be95295d1 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Fri, 1 Feb 2019 20:48:41 +0100 Subject: [PATCH] ath79: add support for Xiaomi Mi Router 4Q Hardware -------- CPU: Qualcomm Atheros QCA9561 RAM: 64M DDR2 FLASH: 16M SPI-NOR ETH: 1x WAN - 2x LAN WiFi: QCA9561 3T3R BTN: 1x Reset - 1x WPS LED: 1x Blue - 1x Red - 1x Yellow UART: TX - GND - RX - VCC (From ethernet port) 115200n8 - 3.3V Installation ------------ 1. Connect to the device via UART. 2. Interrupt the U-Boot on power-on by pressing enter when prompted. 3. Connect you computer to one of the routers LAN ports. Assign yourself the IP 192.168.31.10/24. Copy the OpenWRT initramfs image to a tftp server root directory. Rename the image to 'x4q.bin'. 4. Load the initramfs image to the router by executing following command in U-Boot. The image will boot afterwards. > tftpboot 0x81000000 x4q.bin; bootm 5. SCP the sysupgrade-image into '/tmp'. Remember to assign yourself an IP in 192.168.1.0/24 for this step! 6. Install OpenWRT permanently by executing > sysupgrade -n /tmp/ Signed-off-by: David Bauer --- .../ath79/base-files/etc/board.d/02_network | 5 + .../ath79/dts/qca9561_xiaomi_mi-router-4q.dts | 153 ++++++++++++++++++ target/linux/ath79/image/generic.mk | 7 + 3 files changed, 165 insertions(+) create mode 100644 target/linux/ath79/dts/qca9561_xiaomi_mi-router-4q.dts diff --git a/target/linux/ath79/base-files/etc/board.d/02_network b/target/linux/ath79/base-files/etc/board.d/02_network index ef9a782d92..6bcb7f9955 100755 --- a/target/linux/ath79/base-files/etc/board.d/02_network +++ b/target/linux/ath79/base-files/etc/board.d/02_network @@ -216,6 +216,11 @@ ath79_setup_interfaces() ucidef_add_switch "switch0" \ "0@eth0" "2:lan" "3:wan" ;; + xiaomi,mi-router-4q) + ucidef_set_interface_wan "eth0" + ucidef_add_switch "switch0" \ + "0@eth1" "3:lan:1" "4:lan:2" + ;; *) ucidef_set_interfaces_lan_wan "eth0" "eth1" ;; diff --git a/target/linux/ath79/dts/qca9561_xiaomi_mi-router-4q.dts b/target/linux/ath79/dts/qca9561_xiaomi_mi-router-4q.dts new file mode 100644 index 0000000000..8b8818c82f --- /dev/null +++ b/target/linux/ath79/dts/qca9561_xiaomi_mi-router-4q.dts @@ -0,0 +1,153 @@ +// SPDX-License-Identifier: GPL-2.0+ OR MIT +/dts-v1/; + +#include +#include + +#include "qca956x.dtsi" + +/ { + compatible = "xiaomi,mi-router-4q", "qca,qca9560"; + model = "Xiaomi Mi Router 4Q"; + + aliases { + led-boot = &led_yellow; + led-failsafe = &led_red; + led-running = &led_blue; + led-upgrade = &led_red; + }; + + chosen { + bootargs = "console=ttyS0,115200n8"; + }; + + keys { + compatible = "gpio-keys-polled"; + poll-interval = <100>; + + reset { + label = "Reset button"; + linux,code = ; + gpios = <&gpio 21 GPIO_ACTIVE_LOW>; + }; + + wps { + label = "WPS/MI button"; + linux,code = ; + gpios = <&gpio 19 GPIO_ACTIVE_LOW>; + }; + }; + + leds { + compatible = "gpio-leds"; + + led_red: led_red { + label = "mi-router-4q:red:led"; + gpios = <&gpio 1 GPIO_ACTIVE_LOW>; + }; + + led_yellow: led_yellow { + label = "mi-router-4q:yellow:led"; + gpios = <&gpio 22 GPIO_ACTIVE_LOW>; + }; + + led_blue: led_blue { + label = "mi-router-4q:blue:led"; + gpios = <&gpio 14 GPIO_ACTIVE_LOW>; + }; + }; +}; + +&uart { + status = "okay"; +}; + +&gpio { + status = "okay"; +}; + +&spi { + status = "okay"; + num-cs = <1>; + + flash@0 { + compatible = "jedec,spi-nor"; + reg = <0>; + spi-max-frequency = <25000000>; + + partitions { + compatible = "fixed-partitions"; + #address-cells = <1>; + #size-cells = <1>; + + partition@0 { + label = "u-boot"; + reg = <0x000000 0x30000>; + read-only; + }; + + partition@30000 { + label = "nvram"; + reg = <0x030000 0x10000>; + read-only; + }; + + partition@40000 { + label = "boarddata"; + reg = <0x40000 0x10000>; + read-only; + }; + + partition@50000 { + label = "crash"; + reg = <0x50000 0x10000>; + read-only; + }; + + art: partition@60000 { + label = "art"; + reg = <0x60000 0x10000>; + read-only; + }; + + partition@70000 { + label = "cfg_bak"; + reg = <0x70000 0x20000>; + read-only; + }; + + partition@90000 { + label = "overlay"; + reg = <0x90000 0x170000>; + read-only; + }; + + partition@200000 { + compatible = "denx,uimage"; + label = "firmware"; + reg = <0x200000 0xe00000>; + }; + }; + }; +}; + +ð0 { + status = "okay"; + + phy-handle = <&swphy4>; + mtd-mac-address = <&art 0x0>; +}; + +ð1 { + status = "okay"; + + mtd-mac-address = <&art 0x6>; +}; + +&wmac { + status = "okay"; + + mtd-cal-data = <&art 0x1000>; + mtd-mac-address = <&art 0x0>; + mtd-mac-address-increment = <1>; +}; diff --git a/target/linux/ath79/image/generic.mk b/target/linux/ath79/image/generic.mk index 9d0412fe97..94dfe3d4d7 100644 --- a/target/linux/ath79/image/generic.mk +++ b/target/linux/ath79/image/generic.mk @@ -528,3 +528,10 @@ define Device/winchannel_wb2000 DEVICE_PACKAGES := kmod-i2c-core kmod-i2c-gpio kmod-rtc-ds1307 kmod-usb2 kmod-usb-ledtrig-usbport endef TARGET_DEVICES += winchannel_wb2000 + +define Device/xiaomi_mi-router-4q + ATH_SOC := qca9561 + DEVICE_TITLE := Xiaomi Mi Router 4Q + IMAGE_SIZE := 14336k +endef +TARGET_DEVICES += xiaomi_mi-router-4q -- 2.25.1
