**What's new** * Bring support for the Bananapi BPi-R64 to the level desirable for a nice hackable routerboard. * Use ARM Trusted Firmware A from source. (goodbye binary preloader) * Use Das U-Boot from source. (see previous commit) * Assemble SD-card image using OpenWrt image-commands. (no gen_sd_cruz_foo.sh added, this is not Raspbian) * Updated kernel options to support root filesystem. * Updated DTS to match OpenWrt LAN ports, known LEDs, buttons, ... * Detect root device, handle sysupgrade, config restore, ... * Wire up (known) LEDs and buttons in OpenWrt-fashion. * Build one set of images from SD-card and eMMC. * Hopefully provide a good example of how things can be done right from scratch. **Installation and images** * Have an empty SD-card at hand * Write stuff to the card, as root (card device is /dev/mmcblkX) - write header, gpt, bl2, atf, u-boot and recovery kernel: `cat *bpi-r64-boot-sdcard.img *bpi-r64-initramfs-recovery.fit > /dev/mmcblkX` - rescan partitions: `blockdev --rereadpt /dev/mmcblkX` - write main system to production partition: `cat *bpi-r64-squashfs-sysupgrade.fit > /dev/mmcblkXp5` * Installation to eMMC works using SD-card bootloader via TFTP When running OpenWrt of SD-card, issue this to trigger installation to eMMC: `fw_setenv bootcmd run emmc_init` Be prepared to serve the content of bin/targets/mediatek/mt7622 on TFTP server address 192.168.1.254. **What's missing** * The red LED is always on, probably a hardware bug. * AHCI (probably needs DTS changes) * Ship SD-card image ready with every needed for eMMC install. * The eMMC has a second, currently unused boot partition. This would be ideal to store the WiFi EEPROM and Ethernet MAC address(es). @sinovoip ideas? Thanks to Thomas Hühn @thuehn for providing the hardware! Signed-off-by: Daniel Golle <email@example.com>

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.
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.
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 make4.1+ find grep diff unzip gawk getopt subversion libz-dev libc-dev rsync
./scripts/feeds update -a to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
./scripts/feeds install -a to install symlinks for all obtained
packages into package/feeds/
make menuconfig to select your preferred configuration for the
toolchain, target system & firmware packages.
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
opkg. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
LuCI Web Interface: Modern and modular interface to control the device via a web browser.
OpenWrt Packages: Community repository of ported packages.
OpenWrt Routing: Packages specifically focused on (mesh) routing.
