The M1300 v2 is similar to the WR1300 series from Cudy. Differences: - Only 1 LAN port - No USB Specifications: - MT7621 - MT7603E (2.4G b/g/n) and MT7613BE (5G ac/n) wifi - 128 MB RAM - 16 MB flash MAC Addresses: - There is one on the label, e.g. xx:xx:xx:xx:xx:1C - LAN (bottom connector) is the same as the label, e.g. xx:xx:xx:xx:xx:1C - WAN (top connector) is label +2, e.g. xx:xx:xx:xx:xx:1E - WLAN (2.4G) is the same as the label, e.g. xx:xx:xx:xx:xx:1C - WLAN (5G) is the same as WAN, e.g. xx:xx:xx:xx:xx:1E UART: - is available via the pin holes on the board - From inner to outer pin: TX, RX, GND, VCC - Do NOT connect VCC - Settings: 3.3V, 115200, 8N1 GPIO: - There are two LEDs: Red (GPIO 3) and White (GPIO 4) - There are two buttons: Reset (GPIO 8) and WPS (GPIO 10) Migration to OpenWrt: - Download the migration image from the Cudy website (it should be available as soon as OpenWrt officially supports the device) - The migration image is also available here until a image is provided by Cudy: https://github.com/RolandoMagico/openwrt-build/releases/tag/M1300_Build_20240222 - File: openwrt-ramips-mt7621-cudy_m1300-v2-squashfs-flash-signed.bin - Connect computer to LAN (bottom connector) and flash the migration image via OEM web interface - In the migration image, LAN and WAN are swapped. Computer must be connected to the other port after flashing - OpenWrt is now accessible via 192.168.1.1 - After flashing an up to date OpenWrt image, LAN and WAN settings are again the same as in the OEM firmware - So use the other connector again Revert back to OEM firmware: - Set up a TFTP server on IP 192.168.1.88 and connect to the LAN port (lower port) - Provide the Cudy firmware as recovery.bin in the TFTP server - Press the reset button while powering on the device - Recovery process is started now - When recovery process is done, OEM firmware is accessible via 192.168.10.1 again General information: - No possibility to load a initramfs image via U-Boot because there is no option to interrupt U-Boot Signed-off-by: Roland Reinl <reinlroland+github@gmail.com> Link: https://github.com/openwrt/openwrt/pull/18139 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
