OpenSync root dir

OpenSync build system requires a certain directory structure in order to ensure modularity. Key components are:

• OpenSync core: ${OPENSYNC_ROOT}/core
• OpenSync cfg80211 platform: ${OPENSYNC_ROOT}/platform/cfg80211
• OpenSync vendor layer template: ${OPENSYNC_ROOT}/vendor/openwrt-template
• service provider layer: ${OPENSYNC_ROOT}/service-provider/local

Follow these steps to populate the ${OPENSYNC_ROOT} directory:

$ git clone --branch osync_5.6.0 https://github.com/plume-design/opensync.git ${OPENSYNC_ROOT}/core
$ git clone --branch osync_5.6.0 https://github.com/plume-design/opensync-platform-cfg80211.git ${OPENSYNC_ROOT}/platform/cfg80211
$ git clone --branch osync_5.6.0 https://github.com/plume-design/opensync-vendor-openwrt-template.git ${OPENSYNC_ROOT}/vendor/openwrt-template
$ git clone --branch osync_5.6.0 https://github.com/plume-design/opensync-service-provider-local.git ${OPENSYNC_ROOT}/service-provider/local
$ mkdir ${OPENSYNC_ROOT}/3rdparty

The resulting layout should be as follows:

${OPENSYNC_ROOT}
├── 3rdparty
│   └── ...
├── core
│   ├── 3rdparty -> ../3rdparty
│   ├── build
│   ├── doc
│   ├── futs
│   ├── interfaces
│   ├── kconfig
│   ├── Makefile
│   ├── ovsdb

├── service-provider
│   └── local
└── vendor
    └── openwrt-template

Setting up OpenWrt

To integrate the OpenSync package into OpenWrt, follow the steps below:

1. Get OpenWrt 21.02 source code from Git server

git clone --branch openwrt-21.02 https://git.openwrt.org/openwrt/openwrt.git
cd openwrt; git checkout b119562a0753c282f3cdab0912810bdbe71a0f68; cd -;

2. Get OpenWrt master source code from Git server

git clone --branch master https://git.openwrt.org/openwrt/openwrt.git mac80211_package
cd mac80211_package; git checkout 5c7e4a9d2e25d5ecc33c3c2650e4f954936c9c69; cd -;

3. Get mtk-openwrt-feeds source code

git clone --branch master https://git01.mediatek.com/openwrt/feeds/mtk-openwrt-feeds
cd mtk-openwrt-feeds; git checkout aa392b3498c8579b07afeed4477a6a1b2f042a44; cd -;

4. Change to the openwrt folder

cp -rf mtk-openwrt-feeds/autobuild_mac80211_release openwrt
cd openwrt; mv autobuild_mac80211_release autobuild

5. Add MTK feed

echo "src-git mtk_openwrt_feed https://git01.mediatek.com/openwrt/feeds/mtk-openwrt-feeds" >> feeds.conf.default

6. Edit autobuild/feeds.conf.default-21.02

src-git packages https://git.openwrt.org/feed/packages.git^f01f54e
src-git luci https://git.openwrt.org/project/luci.git^d30ab74
src-git routing https://git.openwrt.org/feed/routing.git^2c21c16
src-git mtk_openwrt_feed https://git01.mediatek.com/openwrt/feeds/mtk-openwrt-feeds^aa392b3 

7. Copy OpenSync related overlays (package, dependencies, patches) to the openwrt directory

8. Append OpenWrt .config for OpenSync

echo "CONFIG_PACKAGE_opensync=y" >> openwrt.config
echo "CONFIG_OPENSYNC_TARGET=FILOGIC830-AX6000/FILOGIC830-AX8400" >> openwrt.config

Build

1. Run AX6000/AX8400 auto build script (APSoC: MT7986A/B, PCIE: MT7915A/D, MT7916)

./autobuild/mt7986_mac80211/lede-branch-build-sanity.sh

2. Further builds (after the first full build)

./scripts/feeds update –a
make V=s

Image install

Get your image in openwrt/bin/targets/mediatek/mt7986 directory

      2. Upgrade firmware
      3. Upgrade ATF BL2
      4. Upgrade ATF FIP
      5. Upgrade single image
      6. Load image
      7. Start Web failsafe
      0. U-Boot console

2. Select Y

Run image after upgrading? (Y/n):

3. Select 0 - TFTP client (Default)

Available load methods:
    0 - TFTP client (Default)
    1 - Xmodem
    2 - Ymodem
    3 - Kermit
    4 - S-Record

4. Set the IP address and server IP using the TFTP process:

Input U-Boot's IP address: 192.168.1.1
Input TFTP server's IP address: 192.168.1.10
Input IP netmask: 255.255.255.0
Input file name: xxx.bin

Firmware upgrade

Image install utilizes the standard OpenWrt sysupgrade, for example:

$ sysupgrade -v <image-file>

Run

OpenSync will be automatically started at startup -- see /etc/rc.d/S961opensync.

To manually start, stop, or restart OpenSync, use the following commands:

$ /etc/init.d/opensync start|stop|restart

Device access

The preferred way to access the device is through the serial console.

SSH access is also available on all interfaces without password:

• Username: root
