Serial console (UART)
---------------------
V
+-------+-------+-------+-------+
| +3.3V | GND | TX | RX |
+---+---+-------+-------+-------+
|
+--- Don't connect
The R3 (TX line) and R6 (RX line) are absent on the PCB. You should
solder them or solder the jumpers.
Installation (UART)
-------------------
1. Place OpenWrt initramfs image on tftp server with IP 192.168.1.2
2. Attach UART, switch on the router and interrupt the boot process by
pressing 'Ctrl-C'
3. Load and run OpenWrt initramfs image:
tftpboot initramfs-kernel.bin
bootm
4. Once inside OpenWrt, set / update env variables:
fw_setenv baudrate 115200
fw_setenv bootargs "ubi.mtd=ubi0 console=ttyS0,115200n1 loglevel=8 earlycon=uart8250,mmio32,0x11002000 init=/etc/preinit"
fw_setenv fdtcontroladdr
5ffc0e70
fw_setenv ipaddr 192.168.1.1
fw_setenv loadaddr 0x46000000
fw_setenv mtdids "spi-nand0=spi-nand0"
fw_setenv mtdparts "spi-nand0:2M(boot),1M(u-boot-env),50M(ubi0),50M(ubi1),8M(userconfig),4M(tp_data)"
fw_setenv netmask 255.255.255.0
fw_setenv serverip 192.168.1.2
fw_setenv stderr serial@
11002000
fw_setenv stdin serial@
11002000
fw_setenv stdout serial@
11002000
fw_setenv tp_boot_idx 0
5. Run 'sysupgrade -n' with the sysupgrade OpenWrt image
Installation (without UART)
---------------------------
1. Login as root via SSH (router IP, port 20001, password - your web
interface password)
2. Open for editing /etc/hotplug.d/iface/65-iptv (e.g., using WinSCP and
SSH settings from the p.1)
3. Add a newline after "#!/bin/sh":
telnetd -l /bin/login.sh
4. Save "65-iptv" file
5. Toggle "IPTV/VLAN Enable" checkbox in the router web interface and
save
6. Make sure that telnetd is running:
netstat -ltunp | grep 23
7. Login via telnet to router IP, port 23 (no username and password are
required)
8 Upload OpenWrt "initramfs-kernel.bin" to the "/tmp" folder of the
router (e.g., using WinSCP and SSH settings from the p.1)
9. Stock busybox doesn't contain ubiupdatevol command. Hence, we need to
download and upload the full version of busybox to the router. For
example, from here:
https://github.com/xerta555/Busybox-Binaries/raw/master/busybox-arm64
Upload busybox-arm64 to the /tmp dir of the router and run:
in the telnet shell:
cd /tmp
chmod a+x busybox-arm64
10. Check "initramfs-kernel.bin" size:
du -h initramfs-kernel.bin
11. Delete old and create new "kernel" volume with appropriate size
(greater than "initramfs-kernel.bin" size):
ubirmvol /dev/ubi0 -N kernel
ubimkvol /dev/ubi0 -n 1 -N kernel -s 9MiB
12. Write OpenWrt "initramfs-kernel.bin" to the flash:
./busybox-arm64 ubiupdatevol /dev/ubi0_1 /tmp/initramfs-kernel.bin
13. u-boot-env can be empty so lets create it (or overwrite it if it
already exists) with the necessary values:
fw_setenv baudrate 115200
fw_setenv bootargs "ubi.mtd=ubi0 console=ttyS0,115200n1 loglevel=8 earlycon=uart8250,mmio32,0x11002000 init=/etc/preinit"
fw_setenv fdtcontroladdr
5ffc0e70
fw_setenv ipaddr 192.168.1.1
fw_setenv loadaddr 0x46000000
fw_setenv mtdids "spi-nand0=spi-nand0"
fw_setenv mtdparts "spi-nand0:2M(boot),1M(u-boot-env),50M(ubi0),50M(ubi1),8M(userconfig),4M(tp_data)"
fw_setenv netmask 255.255.255.0
fw_setenv serverip 192.168.1.2
fw_setenv stderr serial@
11002000
fw_setenv stdin serial@
11002000
fw_setenv stdout serial@
11002000
fw_setenv tp_boot_idx 0
14. Reboot to OpenWrt initramfs:
reboot
15. Login as root via SSH (IP 192.168.1.1, port 22)
16. Upload OpenWrt sysupgrade.bin image to the /tmp dir of the router
17. Run sysupgrade:
sysupgrade -n /tmp/sysupgrade.bin
Recovery
--------
1. Press Reset button and power on the router
2. Navigate to U-Boot recovery web server (http://192.168.1.1/) and
upload the OEM firmware
Recovery (UART)
---------------
1. Place OpenWrt initramfs image on tftp server with IP 192.168.1.2
2. Attach UART, switch on the router and interrupt the boot process by
pressing 'Ctrl-C'
3. Load and run OpenWrt initramfs image:
tftpboot initramfs-kernel.bin
bootm
4. Do what you need (restore partitions from a backup, install OpenWrt
etc.)
Stock layout

U-Boot at boot checks that all volumes are in place:
+-------------------------------+

| Volume Name: kernel Vol ID: 1|
| Volume Name: rootfs Vol ID: 2|
+-------------------------------+
MAC addresses

| WLAN 2g | 00:eb:xx:xx:xx:be | label |
| WLAN 5g | 00:eb:xx:xx:xx:bd | label-1 |
+---------+-------------------+-----------+
label MAC address was found in UBI partition "tp_data", file
"default-mac". OEM wireless eeprom is also there (file
"MT7986_EEPROM.bin").
