Connect to the serial console. Power up the device and interrupt autoboot when prompted 2. Connect a TFTP server reachable at 192.168.1.0/24 (e.g. 192.168.1.66) to the ethernet port. Serve the OpenWrt initramfs image as "openwrt.bin" 3. To test OpenWrt only, go to step 4 and never execute step 5; To install, auto_recovery should be disabled first, and boot_part should be set to 1 if its current value is not. ath> setenv auto_recovery no ath> setenv boot_part 1 ath> saveenv 4. Boot the initramfs image using U-Boot ath> setenv serverip 192.168.1.66 ath> tftpboot 0x84000000 openwrt.bin ath> bootm 5. Copy the OpenWrt sysupgrade image to the device using scp and install it like a normal upgrade (with no need to keeping config since no config from "previous OpenWRT installation" could be kept at all) # sysupgrade -n /path/to/openwrt/sysupgrade.bin Note: Like many other routers produced by Linksys, it has a dual firmware flash layout, but because I do not know how to handle it, I decide to disable it for more usable space. (That is why the "auto_recovery" above should be disabled before installing OpenWRT.) If someone is interested in generating factory firmware image capable to flash from stock firmware, as well as restoring the dual firmware layout, commented-out layout for the original secondary partitions left in the device tree may be a useful hint. Installation from Web Interface ------------ 1. Login to the router via its web interface (default password: admin) 2. Find the firmware update interface under "Connectivity/Basic" 3. Choose the OpenWrt factory image and click "Start" 4. If the router still boots into the stock firmware, it means that the OpenWrt factory image has been installed to the secondary partitions and failed to boot (since OpenWrt on EA4500 v3 does not support dual boot yet), and the router switched back to the stock firmware on the primary partitions. You have to install a stock firmware (e.g. 3.1.6.172023, downloadable from https://www.linksys.com/support-article?articleNum=148385 ) first (to the secondary partitions) , and after that, install OpenWrt factory image (to the primary partitions). After successful installation of OpenWrt, auto_recovery will be automatically disabled and router will only boot from the primary partitions.
