Installation ------------ The U-Boot CLI is password protected (using the same credentials as the OS). Default is admin/new2day. 1. Download the OpenWrt initramfs-image. Place it into a TFTP server root directory and rename it to 1401A8C0.img. Configure the TFTP server to listen at 192.168.1.10/24. 2. Connect the TFTP server to the access point. 3. Connect to the serial console of the access point. Attach power and interrupt the boot procedure when prompted (bootdelay is 1 second). 4. Configure the U-Boot environment for booting OpenWrt from Ram and flash: $ setenv boot_openwrt 'setenv bootargs; bootm 0xbf230000' $ setenv ramboot_openwrt 'tftpboot 0x85000000; bootm' $ setenv bootcmd 'run boot_openwrt' $ saveenv 5. Load OpenWrt into memory: $ run ramboot_openwrt Wait for the image to boot. 6. Transfer the OpenWrt sysupgrade image to the device. Write the image to flash using sysupgrade: $ sysupgrade -n /path/to/openwrt-sysupgrade.bin
