From 39e4f03fd335d5b5d1259d74fc3f00ad09e7796c Mon Sep 17 00:00:00 2001 From: Dmitry Sokolov Date: Mon, 16 Jan 2023 02:52:27 +0500 Subject: ramips: mt7621: add support for Xiaomi Mi Router 4A Gigabit v2 Device is the same as Xiaomi Mi Router 4A Gigabit, except of: - 5G WiFi is MT7663 - addresses of leds, wifi and eth ports are slightly changed Specs: SoC: MT7621 CPU: 2 x 880 MHz ROM: 16 MB RAM: 128 MB WLAN: MT7603, MT7663 MAC addresses: WAN **** factory 0xe006 (label) LAN *:f7 factory 0xe000 2.4 GHz *:f8 factory 0x0000+0x4 (mtd-eeprom+0x4) 5 GHz *:f9 factory 0x8000+0x4 (mtd-eeprom+0x4) Installation: Factory firmware is based on a custom OpenWrt 17.x. Installation is the same as for Xiaomi Mi Router 4A Gigabit. Probably the easiest way to install is to use the script from this repository: https://github.com/acecilia/OpenWRTInvasion/pull/155 In a more advanced case, you can do everything yourself: - gain access to the device through one of the exploits described in the link above - upload sysupgrade image to /tmp - overwrite stock firmware: # mtd -e OS1 -r write /tmp/sysupgrade.bin OS1 Recovery: Recovery procedure is the same as for Xiaomi Mi Router 4A Gigabit. Possible options can be found here: https://openwrt.org/inbox/toh/xiaomi/xiaomi_mi_router_4a_gigabit_edition One of the ways is to use another router with OpenWrt: - connect both routers by their LAN ports - download stock firmware from [1] - place it inside /tmp/test.bin on the main router - configure PXE/TFTP on the main router - power off 4Av2, hold Reset button, power on - as soon as image download via TFTP starts, Reset can be released - blinking blue wan LED will indicate the end of the flashing process, now router can be rebooted [1] http://cdn.cnbj1.fds.api.mi-img.com/xiaoqiang/rom/r4av2/miwifi_r4av2_firmware_release_2.30.28.bin Signed-off-by: Dmitry Sokolov --- target/linux/ramips/mt7621/base-files/etc/board.d/01_leds | 3 +++ target/linux/ramips/mt7621/base-files/etc/board.d/02_network | 3 ++- 2 files changed, 5 insertions(+), 1 deletion(-) (limited to 'target/linux/ramips/mt7621') diff --git a/target/linux/ramips/mt7621/base-files/etc/board.d/01_leds b/target/linux/ramips/mt7621/base-files/etc/board.d/01_leds index 91f3fe6e93..597d7302ac 100644 --- a/target/linux/ramips/mt7621/base-files/etc/board.d/01_leds +++ b/target/linux/ramips/mt7621/base-files/etc/board.d/01_leds @@ -179,6 +179,9 @@ tplink,re650-v2) tplink,tl-wpa8631p-v3) ucidef_set_led_netdev "lan" "LAN" "green:lan" "br-lan" ;; +xiaomi,mi-router-4a-gigabit-v2) + ucidef_set_led_netdev "wan" "wan" "blue:wan" "wan" "link" + ;; xiaomi,mi-router-ac2100) ucidef_set_led_netdev "wan-blue" "WAN (blue)" "blue:wan" "wan" ;; diff --git a/target/linux/ramips/mt7621/base-files/etc/board.d/02_network b/target/linux/ramips/mt7621/base-files/etc/board.d/02_network index ddbbf9891d..67f58b10b2 100644 --- a/target/linux/ramips/mt7621/base-files/etc/board.d/02_network +++ b/target/linux/ramips/mt7621/base-files/etc/board.d/02_network @@ -72,7 +72,8 @@ ramips_setup_interfaces() xiaomi,mi-router-3g|\ xiaomi,mi-router-3g-v2|\ xiaomi,mi-router-4|\ - xiaomi,mi-router-4a-gigabit) + xiaomi,mi-router-4a-gigabit|\ + xiaomi,mi-router-4a-gigabit-v2) ucidef_set_interfaces_lan_wan "lan1 lan2" "wan" ;; bolt,arion) -- cgit v1.2.3
