MikroTik RB5009 uses RouterBoot as its bootloader like all MikroTik devices running RouterOS, meaning that its not FIT compatible and can only boot ELF images. Now this is not so much of an issue on ARM or MIPS since kernel supports appending DTB-s to it (Or we patch the kernel to embed it), but on ARM64 there is intentionally no such support. RouterBoot will pass a DTB, but its the broken MikroTik one which is a modified reference DTB and incorrect in more places than its valid so we cannot use it to boot our kernel. Thus, the solution is to use an intermediary loader and luckily for us Armada 7040 is well supported in U-Boot which makes it a great option since it supports anything that we will ever need to boot. Upstream U-Boot currently requires the Armada boards to be converted to OF_UPSTREAM before adding anything new and this requires updating all of the drivers to accomodate the Linux DTS, while I plan to do this eventually we will need to keep this board downstream for now. Most stuff is supported in U-Boot, including networking since the switch is preconfigured by RouterBoot. A custom environment is used to try and boot from the following devices: 1. NAND (UBI) 2. USB 3. Networking If NAND boot fails then U-Boot will attempt to boot OpenWrt initramfs from USB or via networking. There is a manual recovery mechanism implemented where if the reset button is held when U-Boot is booting it will try to boot OpenWrt initramfs from: 1. USB 2. Networking When U-Boot is in recovery mode it will light all of the LED-s except the switch ones.

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 -a
to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -a
to install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfig
to select your preferred configuration for the toolchain, target system & firmware packages. -
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.

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.
