Installing OpenWrt on the T-56
Installation on this device is rated moderate. Expect to use a recovery mode, TFTP or a vendor tool rather than a plain web upload. Documented methods: U-Boot TFTP + serial recovery, see devicepage.
1 - Do NOT use 2.5Gbit ports during flashing. Once OpenWrt has been installed, you'll be able to use the 2.5Gbit ports. 2 - By default OpenWrt U-boot layout image is used on T-56 device. Check out OpenWrt Forum topic URL for more info.
