From be3e98ce26da5e737744427e1d59dd1c0508edef Mon Sep 17 00:00:00 2001 From: Sungbo Eo Date: Fri, 7 Feb 2020 20:26:05 +0900 Subject: [PATCH] ramips: append tail to WF2881 initramfs image Stock firmware has a vendor-defined tail at the end of uImage for image validation. This patch enables OpenWrt installation from stock firmware without having to access the UART console. Installation via web interface: 1. Flash **initramfs** image through the stock web interface. 2. Boot into OpenWrt and perform sysupgrade with sysupgrade image.
