Flashing instructions:
======================
Various methods can be used to install the actual image on the flash.
Two easy ones are:
ap51-flash
----------
The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the image to the u-boot when the device boots up.
initramfs from TFTP
-------------------
The serial console (115200 8N1) must be used to access the u-boot shell
during bootup. It can then be used to first boot up the initramfs image
from a TFTP server (here with the IP 192.168.1.21):
setenv serverip 192.168.1.21
setenv ipaddr 192.168.1.1
tftpboot 0x83001000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr
The actual sysupgrade image can then be transferred (on the LAN port) to the
device via
scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/
On the device, the sysupgrade must then be started using
sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin

Warning:
The original firmware does not use the device tree.
This device tree is written based on the content of /sys/devices/platform
and has been tested
Note:
- On the device, matrix keypad rows actually are columns, and the columns actually are rows
- The key code of the CLEAR key of the matrix keypad is BACK in the original firmware.
Issue:
- No drivers in mainline kernel for RFID and Bluetooth.
Flash Instruction:
Using SSH/Telnet:
1. Connect the board to the computer via RJ45 Ethernet
2. Login 10.10.10.1 with root password "szqdingnet123" (SSH Port 22, Telnet Port 9900)
3. Download openwrt firmware on the computer.
4. Setup a http server on computer. And use wget download openwrt firmware from computer
5. Use command "mtd -r write openwrt-ramips-mt76x8-qding_qc202-squashfs-sysupgrade.bin firmware"
to flash
Using U-Boot WebUI:
1. Configure PC with a static IP address 10.10.10.2/24.
2. Open http://10.10.10.1
3. Use "mkqdimg -B qc202 -f openwrt-ramips-mt76x8-qding_qc202-squashfs-sysupgrade.bin" to
make image.
4. Upload factory.bin via U-Boot WebUI.

Device specification
--------------------
SoC: MT7628AN MIPS_24KEc @ 580 MHz 2.4G-bgn 2x2
WiFi: MT7612EN 5G-an, ac 80 MHz 2T2R
Flash: 16 MB
DRAM: 64 MB
Switch: MT7628AN (integrated in SoC)
Ethernet: 1 x 10 /100 Mbps
USB: None
Antennas: 2 x 2,4 GHz and 2 x 5 GHz (all are external and non-detachable)
LEDs: blue/red/amber
Buttons: Reset
Serial: 115200,8n1
MAC addresses as verified by OEM firmware:
------------------------------------------
use address source
LAN *:DD factory 0x28
WAN *:DD factory 0x28
2g *:DE factory 0x4
5g *:DF factory 0x8004
OEM firmware uses VLAN's to create the network interface for WAN and LAN.
Bootloader info:
----------------
The stock bootloader uses a "Dual ROM Partition System".
OS1 is a deep copy of OS2.
The bootloader starts OS2 by default.
To force start OS1 it is needed to set "flag_try_sys2_failed=1".
How to install:
---------------
1- Use OpenWRTInvasion to gain Telnet, SSH and FTP access: https://github.com/acecilia/OpenWRTInvasion
[IP: 192.168.31.1 | Username: root | Password: root | FTP-Port: 21]
2- Connect to router using telnet or ssh.
3- Backup all partitions. Use command "dd if=/dev/mtd0 of=/tmp/mtd0". Copy /tmp/mtd0 to computer using ftp.
4- Copy openwrt-ramips-mt76x8-xiaomi_miwifi-3a-squashfs-sysupgrade.bin to /tmp in router using ftp.
5- Enable UART access and change start image to OS1.
nvram set uart_en=1
nvram set flag_last_success=1
nvram set boot_wait=on
nvram set flag_try_sys2_failed=1
nvram commit
6- Erase OS1 & OS2 and install OpenWrt
mtd erase OS1
mtd erase OS2
mtd -r write /tmp/openwrt-ramips-mt76x8-xiaomi_miwifi-3a-squashfs-sysupgrade.bin OS1
