This project provides a single entry point for OpenSync build system embedded into OpenWrt SDK. The only parameters
that need to be provided are OpenSync TARGET and the SDK_URL (a link to a particular version of the OpenWrt SDK).
That OpenWrt SDK will be downloaded and extracted. The OpenSync feed will then be added, and the OpenSync OpenWrt
package will be built using a docker container. The output is a single OpenSync ipk file.
- A Linux distribution with Docker
- OpenWrt SDK (external dependency)
- Optionally, the QEMU emulator for the example deployment
Let's suppose the package must be built for 18.06.4 OpenWrt on 32-bit armvirt target. The first step is to find
an OpenWrt SDK file for that version and architecture. Open https://downloads.openwrt.org/releases/ and navigate to
18.06.4 -> targets -> armvirt -> 32.
Under "Supplementary Files", locate the openwrt-sdk-*.tar.xz file and copy the link to that file.
Run (for example):
make TARGET=ARMVIRT SDK_URL=https://downloads.openwrt.org/releases/18.06.4/targets/armvirt/32/openwrt-sdk-18.06.4-armvirt-32_gcc-7.3.0_musl_eabi.Linux-x86_64.tar.xz
After a while, the 'menuconfig' window should appear. At this point any custom packages can be selected, but
in most cases it is enough to just save without any changes (keep the suggested .config file name) and exit.
And that's it. When the build finishes, the ipk file should be available in the out/ directory.
First, install qemu-system-arm. For example, on Ubuntu run:
sudo apt-get install qemu-system-arm
Assuming the 18.06.4 32-bit armvirt target is used, navigate to https://downloads.openwrt.org/releases/18.06.4/targets/armvirt/32/.
Under "Image Files", locate the zImage-initramfs image, and copy the link to that file.
Next, run the following command (using the above link):
make start_qemu IMAGE_URL=https://downloads.openwrt.org/releases/18.06.4/targets/armvirt/32/openwrt-18.06.4-armvirt-32-zImage-initramfs
Subsequent uses will not require the IMAGE_URL parameter.
Now, the QEMU console should be started with internet connectivity setup.
From another terminal push the OpenSync ipk package to the /tmp directory, for example:
scp -o StrictHostKeyChecking=no out/opensync_1.0-1_arm_cortex-a15_neon-vfpv4.ipk [email protected]:/tmp
Get back to the QEMU console, and run the following commands:
opkg update
cd /tmp
opkg install opensync_1.0-1_arm_cortex-a15_neon-vfpv4.ipk
This should install and start OpenSync. The logs can be dumped (using logread),
and OVSDB tables can be inspected (using ovsh), for example:
$ /usr/plume/tools/ovsh s AWLAN_Node

If the certificates in opensync/vendor/armvirt/rootfs/common/usr/plume/certs/ are valid,
the target should connect successfully to the cloud controller,
and the "ACTIVE" state should be visible in the Manager table:
$ /usr/plume/tools/ovsh s Manager
