Because some padding values in the TP-Link safeloader image generation were hardcoded, different values were sometimes used throughout a factory image. TP-Link's upgrade images use the same value everywhere, so let's do the same here. Although a lot of TP-Link's safeloader images have padded partition payloads, images for the EAP-series of AC devices don't. This padding is therefore also made optional. By replacing the type of the padding value byte with a wider datatype, new values outside of the previously valid range become available. Use these new values to denote that padding should not be performed. Because char might be signed, also replace the char literals by a numeric literal. Otherwise '\xff' might be sign extended to 0xffff. This results in factory images differing by 1 byte for: * C2600 * ARCHER-C5-V2 * ARCHERC9 * TLWA850REV2 * TLWA855REV1 * TL-WPA8630P-V2-EU * TL-WPA8630P-V2-INT * TL-WPA8630P-V2.1-EU * TLWR1043NDV4 * TL-WR902AC-V1 * TLWR942NV1 * RE200-V2 * RE200-V3 * RE220-V2 * RE305-V1 * RE350-V1 * RE350K-V1 * RE355 * RE450 * RE450-V2 * RE450-V3 * RE500-V1 * RE650-V1 The following factory images no longer have padding, shrinking the factory images by a few bytes for: * EAP225-OUTDOOR-V1 * EAP225-V3 * EAP225-WALL-V2 * EAP245-V1 * EAP245-V3 Signed-off-by: Sander Vanheule <sander@svanheule.net>
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.
gcc binutils bzip2 flex python3 perl make find grep diff unzip gawk getopt
subversion libz-dev libc-dev
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo 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.
