mediatek: filogic: Add new Router model ZBT-Z8106AX-S Device support for zbt-z8106ax-s Specifications: SoC: MediaTek MT7981B RAM: 256MiB Flash: Winbond SPI-NAND 128 MiB Switch: 1 WAN, 4 LAN (Gigabit) MediaTek MT7531 Buttons: Reset Power: DC 12V 1A WiFi: MT7981B 2.4Ghz & 5Ghz USB 3 M2 slot to hold LTE modem 1 nano SIM slot (user controllable) Hardware watchdog (confirmed to work) Router comes in a plastic tower with all antennas internal. - 4 antennas for LTE 4G/5G communication - 2 antennas for Wifi 2.4 GHz - 2 antennas for Wifi 5 GHz Led Layout: Power (green, user controllable, default set to OpenWrt Status) Mobile (green, user controllable) WLAN 2.4G (green, user controllable) WLAN 5G (green, user controllable) WAN (amber, user controllable, set to show eth1) LAN1 (amber, hardware controlled) LAN2 (amber, hardware controlled) LAN3 (amber, hardware controlled) LAN4 (amber, hardware controlled) SIM Slot: Controlled via exported GPIO named SIM. echo "0" > /sys/class/gpio/sim/value - turns off sim slot labelled SIM echo "1" > /sys/class/gpio/sim/value - turns on sim slot labelled SIM --- Installation: A. Through U-Boot menu: - Prepare your connecting computer to use a static IP in network 192.168.1.0/24 like a) 192.168.1.10 netmask 255.255.255.0 (legacy notation) b) 192.168.1.10/24 (CIDR notation) - Power down the router and hold in the Reset button. - While holding in the button power up the router again. - Hold the button in for 10 seconds and then release. - Use your browser to go to 192.168.1.1 - If you see a GUI allowing for flashing firmware then you got the right spot. - Upload the **Factory** image file. Note: U-Boot GUI it can be used to recover from an incorrect firmware flash. B. Through OpenWrt Dashboard: If your router comes with OpenWrt preinstalled (modified by vendor), you can easily upgrade by going to the dashboard (192.168.1.1) and then navigate to "System" -> "Backup/Flash firmware" Flash OpenWRT firmware. Important: Take care to deselect (untick) option "keep settings". Settings done by vendor are incompatible with versions 24.10 or 25.12. MAC Addresses: MAC Addresses were found in Factory partition: offset 0x4 F8:5E:3C:xx:xx:aa --> Router Label -2 offset 0xa F8:5E:3C:xx:xx:bb --> Router Label -1 offset 0x24 F8:5E:3C:xx:xx:cc --> Router Label +1 offset 0x2a F8:5E:3C:xx:xx:yy --> printed on Router Label Hardware Watchdog: Device features a GPIO controlled hardware watchdog. Verfied by removing procd controlled watchdog and seeing device rebooting. --- Notes: The zbt-z8106ax-s could be ordered from vendor with a variety of modems. Mine came with a 4G LTE modem Quectel EC200A. Quectel firmware was at EC200AEUHAR01A30M16. Choices for ordering with 5G LTE were available. Modem communication is set to ethernet control mode (ECM) by vendor. Package modemmanager works fine with Quectel EC200A. You may also decide to use FUjR/Qmodem github repository to have it manage LTE modem. Please take note that internal switch port named lan5 isn't wired to LTE modem in model S as opposed to model T. Just removing lan5 from DTS did cause unwanted reboots whenever a cable is plugged into LAN ports 1-4. Disabling port lan5 in DTS however works fine. No unwanted reboots due to plug/unplug cable into any lan or wan port. Signed-off-by: Jörg Seitz Link: https://github.com/openwrt/openwrt/pull/22912 Signed-off-by: Hauke Mehrtens
