mediatek: add Xiaomi Redmi Router AX6000 support
Hardware specification:
SoC: MediaTek MT7986A 4x A53
Flash: ESMT F50L1G41LB 128 MB
RAM: K4A4G165WF-BCWE 512 MB
Ethernet: 4x 10/100/1000 Mbps
WiFi1: MT7976GN 2.4GHz ax 4x4
WiFi2: MT7976AN 5GHz ax 4x4
Button: Mesh, Reset
Flash instructions:
1. Gain ssh and serial port access, see the link below:
https://openwrt.org/toh/xiaomi/redmi_ax6000#installation
2. Use ssh or serial port to log in to the router, and
execute the following command:
nvram set boot_wait=on
nvram set flag_boot_rootfs=0
nvram set flag_boot_success=1
nvram set flag_last_success=1
nvram set flag_try_sys1_failed=8
nvram set flag_try_sys2_failed=8
nvram commit
3. Set a static ip on the ethernet interface of your computer
(e.g. default: ip 192.168.31.100, gateway 192.168.31.1)
4. Download the initramfs image, rename it to initramfs.bin,
and host it with the tftp server.
5. Interrupt U-Boot and run these commands:
setenv mtdparts nmbm0:1024k(bl2),256k(Nvram),256k(Bdata),2048k(factory),2048k(fip),256k(crash),256k(crash_log),112640k(ubi)
saveenv
tftpboot initramfs.bin
bootm
6. After openwrt boots up, use scp or luci web
to upload sysupgrade.bin to upgrade.
Revert to stock firmware:
Restore mtdparts back to default, then use the
vendor's recovery tool (Windows only).
