Michael Pratt 4a0cc5d4ef ath79: remove 'fakeroot' for Senao devices 
By using the same custom kernel header magic
in both OKLI lzma-loader, DTS, and makefile
this hack is not necessary anymore

However, "rootfs" size and checksum
must now be supplied by the factory.bin image
through a script that is accepted by the OEM upgrade script.

This is because Senao OEM scripts assume a squashfs header exists
at the offset for the original "rootfs" partition
which is actually the kernel + rootfs in this implementation,
and takes size value from the header that would be there with hexdump,
but this offset is now the uImage header instead.

This frees up 1 eraseblock
previously used by the "fakeroot" partition
for bypassing the OEM image verification.

Also, these Senao devices with a 'failsafe' partition
and the tar-gz factory.bin platform would otherwise require
flashing the new tar-gz sysupgrade.bin afterward.
So this also prevents having to flash both images
when starting from OEM or 'failsafe'

the OEM upgrade script verifies the header magic numbers,
but only the first two bytes.
Example:

    [ "${magic_word_kernel}" = "2705" ] &&
    [ "${magic_word_rootfs}" = "7371" -o "${magic_word_rootfs}" = "6873" ] &&
    errcode="0"

therefore picked the magic number
0x73714f4b
which is
'sqOK'

OpenWrt logo

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Sunshine!

Development

To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.

Requirements

You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.

binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.6+ rsync subversion unzip which

Quickstart

  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 GNU/Linux kernel & all chosen applications for your target system.

Related Repositories

The main repository uses multiple sub-repositories to manage packages of different categories. All packages are installed via the OpenWrt package manager called opkg. If you're looking to develop the web interface or port packages to OpenWrt, please find the fitting repository below.
