From a51e46e543ef2e923fb97fb092d04355dfca7d7d Mon Sep 17 00:00:00 2001 From: Adrian Schmutzler Date: Thu, 12 Nov 2020 16:00:10 +0100 Subject: ramips: add Xiaomi Mi Router 4A Gigabit explicitly This device has previously been supported by the image for Xiaomi Mi Router 3G v2. Since this is not obvious, the 4A is marketed as a new major revision and it also seems to have a different bootloader, this will be both more tidy and more helpful for the users. Apart from that, note that there also is a 100M version of the device that uses mt7628 platform, so a specifically named image will also prevent confusion in this area. Specifications: - SoC: MediaTek MT7621 - Flash: 16 MiB NOR SPI - RAM: 128 MiB DDR3 - Ethernet: 3x 10/100/1000 Mbps (switched, 2xLAN + WAN) - WIFI0: MT7603E 2.4GHz 802.11b/g/n - WIFI1: MT7612E 5GHz 802.11ac - Antennas: 4x external (2 per radio), non-detachable - LEDs: Programmable "power" LED (two-coloured, yellow/blue) Non-programmable "internet" LED (shows WAN activity) - Buttons: Reset Installation: Bootloader won't accept any serial input unless "boot_wait" u-boot environment variable is changed to "on". Vendor firmware won't accept any serial input until "uart_en" is set to "1". Using the https://github.com/acecilia/OpenWRTInvasion exploit you can gain access to shell to enable these options: To enable uart keyboard actions - 'nvram set uart_en=1' To make uboot delay boot work - 'nvram set boot_wait=on' Set boot delay to 5 - 'nvram set bootdelay=5' Then run 'nvram commit' to make the changes permanent. Once in the shell (following the OpenWRTInvasion instructions) you can then run the following to flash OpenWrt and then reboot: 'cd /tmp; curl https://downloads.openwrt.org/...-sysupgrade.bin --output firmware.bin; mtd -e OS1 -r write firmware.bin OS1' Suggested-by: David Bentham Signed-off-by: Adrian Schmutzler --- .../dts/mt7621_xiaomi_mi-router-4a-3g-v2.dtsi | 161 +++++++++++++++++++++ .../dts/mt7621_xiaomi_mi-router-4a-gigabit.dts | 8 + target/linux/ramips/dts/mt7621_xiaomi_mir3g-v2.dts | 157 +------------------- target/linux/ramips/image/mt7621.mk | 14 +- .../mt7621/base-files/etc/board.d/02_network | 3 +- 5 files changed, 183 insertions(+), 160 deletions(-) create mode 100644 target/linux/ramips/dts/mt7621_xiaomi_mi-router-4a-3g-v2.dtsi create mode 100644 target/linux/ramips/dts/mt7621_xiaomi_mi-router-4a-gigabit.dts diff --git a/target/linux/ramips/dts/mt7621_xiaomi_mi-router-4a-3g-v2.dtsi b/target/linux/ramips/dts/mt7621_xiaomi_mi-router-4a-3g-v2.dtsi new file mode 100644 index 0000000000..65b299e425 --- /dev/null +++ b/target/linux/ramips/dts/mt7621_xiaomi_mi-router-4a-3g-v2.dtsi @@ -0,0 +1,161 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT + +#include "mt7621.dtsi" + +#include +#include + +/ { + aliases { + led-boot = &led_status_yellow;
