ramips: add support for Tenbay T-MB5EU-V01 Hardware -------- MediaTek MT7621 SoC 256M DDR3 16MB BoHong SPI-NOR MediaTek MT7905+7975 2x2T2R DBDC bgnax / acax RGB LED WPS + RESET Button UART on compute module (silkscreened / 115200n8) The router itself is just a board with Power / USB / RJ-45 connectors and DC/DC converters. The SoC and WiFi components are on a daughterboard which connect using two M.2 connectors. The compute module has the model number "T-CB1800K-DM2 V02" printed on it. The main baord has "T-MB5EU V01" printed on it. This information might be useful, as it's highly likely either of these two will be reused in similar designs. The router itself is sold as Tenbay T-MB5EU directly from the OEM as well as "KuWFI AX1800 Smart WiFi 6 Eouter" on Amazon.de for ~50€ in a slightly different case. Installation ------------ A Tool for creating a factory image for the Vendor Web Interface can be found here: https://github.com/blocktrron/t-mb5eu-v01-factory-creator/ As the OEM Firmware is just a modified LEDE 17.01, you can also access failsafe mode via UART while the OS boots, by connecting to UART and pressing "f" when prompted. The Router is reachable at 192.168.1.1 via root without password. Transfer the OpenWrt sysupgrade image via scp and apply with sysupgrade using the -n and -F flags. Alternatively, the board can be flashed by attaching to the UART console, interrupting the boot process by keeping "0" pressed while attaching power. Serve the OpenWrt initramfs using a TFTP server with address 192.168.1.66. Rename the initramfs to ax1800.bin. Attach your TFTP server to one of the LAN ports. Execute the following commands. $ setenv ipaddr 192.168.1.67 $ setenv serverip 192.168.1.66 $ tftpboot 0x84000000 ax1800.bin $ bootm Wait for the device to boot. Then transfer the OpenWrt sysupgrade image to the device using SCP and apply sysupgrade.
