Fix two hardware initialization issues in the EN7581 PCIe controller and add support for x2 (2-lane) link mode. Fixes: The upstream EN7581 PCIe initialization writes EQ presets and PIPE configuration registers before clk_bulk_prepare_enable(). Since the MAC clocks are not yet running at that point, these register writes are silently dropped, leaving the hardware with default values. This can cause link training failures or suboptimal equalization. Additionally, after link training the MAC may only advertise Gen1-Gen2 capability in the Link Capabilities 2 register despite the PHY being configured for Gen3. A serdes reset toggle forces the MAC to re-read PHY capability, recovering Gen3 8GT/s link speed. Both issues are addressed by separating PERST from the clock callbacks (patch 911), allowing the PCIe controller driver to properly sequence PERST, clock enable, and register writes (patch 912). New feature: PCIe x2 mode support for EN7581 using the NP_SCU system controller for serdes mux routing, PERST management, and lane configuration. Both bonded MACs are configured for x2 operation with proper EQ presets before link training begins.

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!
Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
Development
To build your own firmware you need a GNU/Linux, BSD or macOS 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 python3.7+ rsync subversion unzip which
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.
