The latest bootloader versions load the firmware into memory and call `chk_dniimg` (defined in Netgear GPL release), which expects to find three consecutive block-aligned uImages. Add two fake uImage headers after the kernel to fool this check. This wastes up to 128k of space for alignment. The alternative would be to put the rootfs in a second uImage, but this would limit the firmware size to 0x710000 (the number of bytes loaded and verified by the bootloader) instead of 0x7b0000 (the size of the firmware partition).

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
