On other occasions Cudy has distributed intermediate firmware to make installation easier, and so I recommend checking the Wiki for this device if there is a more convenient solution than the one below. To install using TFTP: 1. Connect to UART. 2. With the router off, press the RESET button. While the router is turning on, the button should continue to be pressed for at least 5 seconds. 3. A u-boot shell will automatically open. 4. Connect to LAN and set your IP to 192.168.1.88/24. Configure a TFTP server and an OpenWrt initramfs-kernel.bin firmware file. 5. Run these steps in u-boot using the name of your file. setenv bootfile initramfs-kernel.bin tftpboot bootm 6. If you can reach LuCI or SSH now, just use the sysupgrade image with the 'Keep settings' option turned off. Signed-off-by: Luis Mita <luis@luismita.com> |
