From 14e0e4f138e35c3e2a15cc3a836c939547ee053b Mon Sep 17 00:00:00 2001 From: David Bauer Date: Thu, 11 Jul 2019 17:15:48 +0200 Subject: [PATCH] ramips: add support for ASUS RT-AC57U SoC: MediaTek MT7621AT RAM: 128M (Winbond W631GG6KB-15) FLASH: 16MB (Spansion S25FL128SA) WiFi: MediaTek MT7603EN bgn 2SS WiFi: MediaTek MT7612EN nac 2SS BTN: Reset - WPS LED: - Power - LAN {1-4} - WAN - WiFi 2.4 GHz - WiFi 5 GHz - USB UART: UART is present next to the Power LED. TX - RX - GND - 3V3 / 57600-8N1 3V3 is the nearest one to the Power LED. Installation ------------ Via TFTP: 1. Set your computers IP-Address to 192.168.1.75. 2. Power up the Router with the Reset button pressed. 3. Release the Reset button after 5 seconds. 4. Upload OpenWRT sysupgrade image via TFTP: > tftp -4 -v -m binary 192.168.1.1 -c put Via SSH: Note: User/password for SSH is identical with the one used in the Web-interface. 1. Complete the initial setup wizard. 2. Activate SSH under "Administration" -> "System". 3. Transfer the OpenWrt sysupgrade image via scp: > scp owrt.bin admin@192.168.1.1:/tmp 4. Connect via SSH to the router. > ssh admin@192.168.1.1 5. Write the OpenWrt image to flash. > mtd-write -i /tmp/owrt.bin -d linux 6. Reboot the router > reboot Signed-off-by: David Bauer --- .../ramips/base-files/etc/board.d/02_network | 10 +- .../linux/ramips/dts/mt7621_asus_rt-ac57u.dts | 148 ++++++++++++++++++ target/linux/ramips/image/mt7621.mk | 9 ++ 3 files changed, 163 insertions(+), 4 deletions(-) create mode 100644 target/linux/ramips/dts/mt7621_asus_rt-ac57u.dts diff --git a/target/linux/ramips/base-files/etc/board.d/02_network b/target/linux/ramips/base-files/etc/board.d/02_network index 688ce55570..c3b7cd4390 100755 --- a/target/linux/ramips/base-files/etc/board.d/02_network +++ b/target/linux/ramips/base-files/etc/board.d/02_network @@ -186,6 +186,7 @@ ramips_setup_interfaces() argus,atp-52b|\ asiarf,awm002-evb-4m|\ asiarf,awm002-evb-8m|\ + asus,rt-ac57u|\ asus,rt-n14u|\ bdcom,wap2100-sk|\ dlink,dir-645|\ @@ -521,6 +522,11 @@ ramips_setup_macs() lan_mac=$(macaddr_setbit_la "$lan_mac") wan_mac=$(macaddr_add "$lan_mac" 1) ;; + asus,rt-ac57u|\ + planex,vr500) + lan_mac=$(mtd_get_mac_binary factory 57344) + wan_mac=$(mtd_get_mac_binary factory 57350) + ;; asus,rt-n56u) lan_mac=$(cat /sys/class/net/eth0/address) lan_mac=$(macaddr_setbit_la "$lan_mac") @@ -641,10 +647,6 @@ ramips_setup_macs() wan_mac=$(mtd_get_mac_binary factory 4) lan_mac=$(mtd_get_mac_binary factory 46) ;; - planex,vr500) - lan_mac=$(mtd_get_mac_binary factory 57344) - wan_mac=$(mtd_get_mac_binary factory 57350) - ;; poray,m3|\ poray,m4-4m|\ poray,m4-8m|\ diff --git a/target/linux/ramips/dts/mt7621_asus_rt-ac57u.dts b/target/linux/ramips/dts/mt7621_asus_rt-ac57u.dts new file mode 100644 index 0000000000..8060fd9eaa --- /dev/null +++ b/target/linux/ramips/dts/mt7621_asus_rt-ac57u.dts @@ -0,0 +1,148 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT +/dts-v1/; + +#include "mt7621.dtsi" + +#include +#include + +/ { + compatible = "asus,rt-ac57u", "mediatek,mt7621-soc"; + model = "ASUS RT-AC57U"; + + aliases { + led-boot = &led_power; + led-failsafe = &led_power; + led-running = &led_power; + led-upgrade = &led_power; + }; + + chosen { + bootargs = "console=ttyS0,57600"; + }; + + leds { + compatible = "gpio-leds"; + + led_power: power { + label = "rt-ac57u:blue:power"; + gpios = <&gpio1 16 GPIO_ACTIVE_LOW>; + }; + + usb { + label = "rt-ac57u:blue:usb"; + gpios = <&gpio1 15 GPIO_ACTIVE_LOW>; + trigger-sources = <&ehci_port2>; + linux,default-trigger = "usbport"; + }; + }; + + keys { + compatible = "gpio-keys"; + + wps { + label = "wps"; + gpios = <&gpio1 11 GPIO_ACTIVE_HIGH>; + linux,code = ; + debounce-interval = <60>; + }; + + reset { + label = "reset"; + gpios = <&gpio1 9 GPIO_ACTIVE_LOW>; + linux,code = ; + debounce-interval = <60>; + }; + }; + + led-regulator { + compatible = "regulator-fixed"; + regulator-name = "LED-Power"; + gpio = <&gpio1 14 GPIO_ACTIVE_LOW>; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + regulator-always-on; + }; +}; + +&spi0 { + status = "okay"; + + flash@0 { + compatible = "jedec,spi-nor"; + reg = <0>; + spi-max-frequency = <10000000>; + + partitions { + compatible = "fixed-partitions"; + #address-cells = <1>; + #size-cells = <1>; + + partition@0 { + label = "u-boot"; + reg = <0x0 0x30000>; + read-only; + }; + + partition@30000 { + label = "config"; + reg = <0x30000 0x10000>; + read-only; + }; + + factory: partition@40000 { + label = "factory"; + reg = <0x40000 0x10000>; + read-only; + }; + + partition@50000 { + compatible = "denx,uimage"; + label = "firmware"; + reg = <0x50000 0xfb0000>; + }; + }; + }; +}; + +&pcie { + status = "okay"; +}; + +&pcie0 { + wifi@0,0 { + compatible = "mediatek,mt76"; + reg = <0x0000 0 0 0 0>; + mediatek,mtd-eeprom = <&factory 0x8000>; + + led { + led-sources = <2>; + led-active-low; + }; + }; +}; + +&pcie1 { + wifi@0,0 { + compatible = "mediatek,mt76"; + reg = <0x0000 0 0 0 0>; + mediatek,mtd-eeprom = <&factory 0x0000>; + + led { + led-active-low; + }; + }; +}; + +ðernet { + mtd-mac-address = <&factory 0x4e000>; +}; + +&pinctrl { + state_default: pinctrl0 { + gpio { + ralink,group = "sdhci"; + ralink,function = "gpio"; + }; + }; +}; diff --git a/target/linux/ramips/image/mt7621.mk b/target/linux/ramips/image/mt7621.mk index 1cd9092b14..e2928c80ce 100644 --- a/target/linux/ramips/image/mt7621.mk +++ b/target/linux/ramips/image/mt7621.mk @@ -106,6 +106,15 @@ define Device/asiarf_ap7621-001 endef TARGET_DEVICES += asiarf_ap7621-001 +define Device/asus_rt-ac57u + MTK_SOC := mt7621 + DEVICE_VENDOR := ASUS + DEVICE_MODEL := RT-AC57U + IMAGE_SIZE := 16064k + DEVICE_PACKAGES := kmod-mt7603 kmod-mt76x2 kmod-usb3 kmod-usb-ledtrig-usbport wpad-basic +endef +TARGET_DEVICES += asus_rt-ac57u + define Device/buffalo_wsr-1166dhp MTK_SOC := mt7621 IMAGE/sysupgrade.bin := trx | pad-rootfs | append-metadata -- 2.25.1
