Cudy LT700 Outdoor v1 is an outdoor 4G LTE Wi-Fi 5 router (Cudy board ID R43). Hardware: - SoC: MediaTek MT7621AT - Flash: 16 MiB SPI NOR (XM25QH128C) - RAM: 128 MiB DDR3 - WLAN: 2.4 GHz (MediaTek MT7603E, 11n), 5 GHz (MediaTek MT7663, 11ac) - Ethernet: 1x 10/100/1000 Mbps LAN - Power: 48-57 V passive PoE - Buttons: 1x Reset button - LEDs: 8x Green - LTE: internal USB modem Quectel EG060W (Cat 6) - Serial console: 3.3V, 115200 8N1, unpopulated 4-pin header left of the SoC; pinout from top: VCC, GND, TX, RX MAC addresses: +---------+-------------------+-----------+ | | MAC | Algorithm | +---------+-------------------+-----------+ | LAN | d4:0d:ab:xx:xx:xx | label | | WLAN 2g | d4:0d:ab:xx:xx:xx | label | | WLAN 5g | d4:0d:ab:xx:xx:xx | label +1 | +---------+-------------------+-----------+ The internal LTE modem is a Quectel EG060W and needs the option driver IDs added in a separate commit. gpio-export applies the initial output value raw, ignoring the active-low flag, so output = <0> is what pulls the modem power enable low and powers it at boot. Migration to OpenWrt: - Obtain the RSA signed intermediate firmware from Cudy: openwrt-ramips-mt7621-cudy_lt700-outdoor-v1-squashfs-flash.bin - Connect a computer to the LAN port and flash the intermediate firmware via the OEM web interface - OpenWrt is now accessible via 192.168.1.1 - Install the regular OpenWrt sysupgrade image from LuCI or over SSH Revert back to OEM firmware: - Configure a computer with IP 192.168.1.88 and run a TFTP server that serves the OEM recovery image as recovery.bin - Hold the reset button while powering on the device; the bootloader fetches recovery.bin and restores the OEM firmware Signed-off-by: Carlo Szelinsky <github@szelinsky.de> Tested-by: achim <achim@cloudystars.net> Link: https://github.com/openwrt/openwrt/pull/24689 Signed-off-by: Jonas Jelonek <jonas@jonasjelonek.de>
