Certain boards have limitations on U-Boot that prevent flashing
of images where the kernel size exceeds a threshold, yet
sysupgrade can sucessfully manage larger kernels. The current
check-size will remove the target artifact if its total size
exceeds the threshold. If applied after append-kernel,
it will remove the kernel, but the remaining image-assembly
steps will continue, resulting in an image without a kernel
that is likely unbootable.
By defining check-kernel-size, it is now possible to prevent release
of such unbootable images through a construct similar to:
IMAGE/factory.img := append-kernel | pad-to $$$$(GL_UBOOT_UBI_OFFSET) | \
append-ubi | check-kernel-size $$$$(GL_UBOOT_UBI_OFFSET)

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
