X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c2a7bb520a0fb107984ad3757174d391796cd222;p=openwrt%2Fstaging%2Fadrian.git
ramips: mt7621: add support for Xiaomi Mi Router 4
Xiaomi Mi Router 4 is the same as Xiaomi Mi Router 3G, except for
the RAM (256Mib→128Mib), LEDs and gpio (MiNet button).
Specifications:
Power: 12 VDC, 1 A
Connector type: barrel
CPU1: MediaTek MT7621A (880 MHz, 4 cores)
FLA1: 128 MiB (ESMT F59L1G81MA)
RAM1: 128 MiB (ESMT M15T1G1664A)
WI1 chip1: MediaTek MT7603EN
WI1 802dot11 protocols: bgn
WI1 MIMO config: 2x2:2
WI1 antenna connector: U.FL
WI2 chip1: MediaTek MT7612EN
WI2 802dot11 protocols: an+ac
WI2 MIMO config: 2x2:2
WI2 antenna connector: U.FL
ETH chip1: MediaTek MT7621A
Switch: MediaTek MT7621A
UART Serial
[o] TX
[o] GND
[o] RX
[ ] VCC - Do not connect it
MAC addresses as verified by OEM firmware:
use address source
LAN *:c2 factory 0xe000 (label)
WAN *:c3 factory 0xe006
2g *:c4 factory 0x0000
5g *:c5 factory 0x8000
Flashing instructions:
1.Create a simple http server (nginx etc)
2.set uart enable
To enable writing to the console, you must reset to factory settings
Then you see uboot boot, press the keyboard 4 button (enter uboot command line)
If it is not successful, repeat the above operation of restoring the factory settings.
After entering the uboot command line, type:
setenv uart_en 1
saveenv
boot
3.use shell in uart
cd /tmp
wget http://"your_computer_ip:80"/openwrt-ramips-mt7621-xiaomi_mir4-squashfs-kernel1.bin
wget http://"your_computer_ip:80"/openwrt-ramips-mt7621-xiaomi_mir4-squashfs-rootfs0.bin
mtd write openwrt-ramips-mt7621-xiaomi_mir4-squashfs-kernel1.bin kernel1
mtd write openwrt-ramips-mt7621-xiaomi_mir4-squashfs-rootfs0.bin rootfs0
nvram set flag_try_sys1_failed=1
nvram commit
reboot
4.login to the router http://192.168.1.1/
