Some Ubiquiti U-boot versions, in particular the "U-Boot 1.1.4.2-s956 (Jun 10 2015 - 10:54:50)" found with AirOS 5.6, do not correctly flush the caches for the whole kernel address range after decompressing the kernel image, leading to hard to debug boot failures, depending on kernel version and configuration. As a workaround, prepend the relocate-kernels loader, which will invalidate the caches after moving the kernel to the correct load address.

This is the buildsystem for the OpenWrt Linux distribution. Please use "make menuconfig" to choose your preferred configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your OpenWrt Community http://www.openwrt.org
