This document describes how to build runtime with GBS for Tizen AARCH64. As a real example, we'll also describe how to prepare Tizen on Raspberry Pi 4 and show you how to run our test package runner onert_run.
For ARM32, there would be not much difference with some changes.
Host PC is Ubuntu 18.04 but other versions or distro may work with a little adjustments.
Detailed technical informations are not described here so please read referecnce pages while you go on.
Setting up build environment
(1) Add Tizen build tools repo
$ sudo vim /etc/apt/sources.list
Add this at the end
deb [trusted=yes] http://download.tizen.org/tools/latest-release/Ubuntu_18.04/ /
Note: There's a slash('/`) at the end.
For other versions of Ubuntu, please refer http://download.tizen.org/tools/latest-release/ lists.
(2) Update package informations and upgrade to latest
$ sudo apt-get update
$ sudo apt-get upgrade
(3) Install GBS tools
$ sudo apt-get install gbs mic
To get more informations, please refer HERE
Build ONERT
(1) Set python2 as default python
Some tools of GBS run in python2 and won't run with python3. Please check python version and set it to 2.x.
(2) set TIZEN_BUILD_ROOT
You may set GBS-ROOT to any place you like. Ususally we use home folder.
$ export TIZEN_BUILD_ROOT=$HOME/GBS-ROOT/
Adding to $HOME/.profile file would be a good thing.
(3) clone ONE repo
git clone https://github.com/Samsung/ONE.git
(4) Build
$ cd ONE
$ gbs -c infra/nnfw/config/gbs.conf build --include-all -A aarch64 --define 'test_build 1'
-A aarch64 is to set architecture to AARCH64. Use arm32 for ARM32 target.- ‘--define 'test_build 1’
is to enable test build so that we can useonert_run`
Now take a cup of coffee.
(5) Build result RPM packages
$ ls ~/GBS-ROOT/local/repos/tizen/aarch64/RPMS
nnfw-1.10.0-1.aarch64.rpm
nnfw-debuginfo-1.10.0-1.aarch64.rpm
nnfw-debugsource-1.10.0-1.aarch64.rpm
nnfw-devel-1.10.0-1.aarch64.rpm
nnfw-minimal-app-1.10.0-1.aarch64.rpm
nnfw-minimal-app-debuginfo-1.10.0-1.aarch64.rpm
nnfw-plugin-devel-1.10.0-1.aarch64.rpm
nnfw-test-1.10.0-1.aarch64.rpm
nnfw-test-debuginfo-1.10.0-1.aarch64.rpm
-1.10.0-1 may differ as this document was written with under 1.10.0 development.
Prepare Tizen on Raspberry Pi 4
Please refer https://wiki.tizen.org/Quick_guide_for_RPI4 for detailed descriptions.
(1) Download flashing tool
$ wget \
https://git.tizen.org/cgit/platform/kernel/u-boot/plain/scripts/tizen/sd_fusing_rpi3.sh?h=tizen \
--output-document=sd_fusing_rpi3.sh
$ chmod 755 sd_fusing_rpi3.sh
(2) Prepare Micro-SD memory card.
You first need to find out device name. This document will skip how to find this. Suppose it's /dev/sdj:
$ sudo ./sd_fusing_rpi3.sh -d /dev/sdj --format
You need to change /dev/sdj to your configuration.
Partition table may look like this
Device Boot Start End Sectors Size Id Type
/dev/sdj1 * 8192 139263 131072 64M e W95 FAT16 (LBA)
/dev/sdj2 139264 6430719 6291456 3G 83 Linux
/dev/sdj3 6430720 9183231 2752512 1.3G 83 Linux
/dev/sdj4 9183232 62521343 53338112 25.4G 5 Extended
/dev/sdj5 9185280 61958143 52772864 25.2G 83 Linux
/dev/sdj6 61960192 62025727 65536 32M 83 Linux
/dev/sdj7 62027776 62044159 16384 8M 83 Linux
/dev/sdj8 62046208 62111743 65536 32M 83 Linux
/dev/sdj9 62113792 62130175 16384 8M 83 Linux
/dev/sdj10 62132224 62263295 131072 64M 83 Linux
/dev/sdj11 62265344 62521343 256000 125M 83 Linux
(3) Download images
Please visit http://download.tizen.org/snapshots/tizen/unified/latest/images/standard/iot-boot-arm64-rpi4/ and http://download.tizen.org/snapshots/tizen/unified/latest/images/standard/iot-headed-3parts-aarch64-rpi.
Please visit iot-boot-armv7l-rpi4 folder for ARM32 images.
Get latest file. As of writing this document, name has 20200908.3.
$ wget http://download.tizen.org/snapshots/tizen/unified/latest/images/standard/iot-boot-arm64-rpi4/tizen-unified_20200908.3_iot-boot-arm64-rpi4.tar.gz
$ wget http://download.tizen.org/snapshots/tizen/unified/latest/images/standard/iot-headed-3parts-aarch64-rpi/tizen-unified_20200908.3_iot-headed-3parts-aarch64-rpi.tar.gz
(4) Flash images to memory card
As like above, suppose memory card is at /dev/sdj
$ sudo ./sd_fusing_rpi3.sh -d /dev/sdj \
-b tizen-unified_20200908.3_iot-boot-arm64-rpi4.tar.gz \
tizen-unified_20200908.3_iot-headed-3parts-aarch64-rpi.tar.gz
You need to change /dev/sdj to your configuration and also tizen-unified_... file to your latest download file name.
(5) Assign IP address for sdb connection
Here, we provide a way to connect sdb tool through TCP/IP.
Below steps will modify root image and set fixed IP address.
(5-1) Mount image to host
$ mkdir j2
$ sudo mount /dev/sdj2 j2
As like above, please update /dev/sdj2 to your configuration.
(5-2) Add a new file
$ vi j2/etc/systemd/system/ip.service
and set as like:
[Service]
Restart=always
RestartSec=1
User=root
ExecStart=/bin/sh -c "ifconfig eth0 192.168.x.y netmask 255.255.255.0 up"
[Install]
WantedBy=multi-user.target
Replace 192.168.x.y to your actual ip address.
(5-3) Add a symbolic link
$ sudo mkdir -p j2/etc/systemd/system/multi-user.target.wants/
$ pushd j2/etc/systemd/system/multi-user.target.wants/
$ sudo ln -s ../../system/ip.service .
$ popd
(5-4) Now that every thing is ready, unmount and unplug your memory card and plug into RPi4, turn on the power.
sdb connect to Tizen/RPi4
You may need to install Tizen Studio to use sdb command. Please visit https://developer.tizen.org/ if you don't have this.
We assume sdb command is in the PATH.
(1) Connect
$ sdb connect 192.168.x.y
connecting to 192.168.x.y:26101 ...
connected to 192.168.x.y:26101
Please update 192.168.x.y part to your actual IP address.
Check with devices command: you should see rpi3 or alike.
$ sdb devices
List of devices attached
192.168.x.y:26101 device rpi3
(2) Remount filesystem with R/W
You need to remount file system with Read/Write so that you can install packages.
$ sdb root on
$ sdb shell
Inside your Tizen/RPi4:
sh-3.2# mount -o rw,remount /
(3) Download dependent packages
In your host, maybe with another terminal, download packages from http://download.tizen.org/releases/daily/tizen/unified/latest/repos/standard/packages/aarch64/
$ wget http://download.tizen.org/releases/daily/tizen/unified/latest/repos/standard/packages/aarch64/libarmcl-v21.02-17.5.aarch64.rpm
$ wget http://download.tizen.org/releases/daily/tizen/unified/latest/repos/standard/packages/aarch64/libhdf5-101-1.10.1-3.85.aarch64.rpm
$ wget http://download.tizen.org/releases/daily/tizen/unified/latest/repos/standard/packages/aarch64/libhdf5_cpp101-1.10.1-3.85.aarch64.rpm
(4) Copy to device
$ sdb push libarmcl-v21.02-17.5.aarch64.rpm /opt/usr/home/owner/share/tmp/
$ sdb push libhdf5-101-1.10.1-3.85.aarch64.rpm /opt/usr/home/owner/share/tmp/
$ sdb push libhdf5_cpp101-1.10.1-3.85.aarch64.rpm /opt/usr/home/owner/share/tmp/
And our runtime packages
$ cd ~/GBS-ROOT/local/repos/tizen/aarch64/RPMS
$ sdb push nnfw-1.10.0-1.aarch64.rpm /opt/usr/home/owner/share/tmp/
$ sdb push nnfw-test-1.10.0-1.aarch64.rpm /opt/usr/home/owner/share/tmp/
(5) Install dependent packages
Within Tizen/RPi4 shell
sh-3.2# cd /opt/usr/home/owner/share/tmp/
sh-3.2# rpm -i libarmcl-v21.02-17.5.aarch64.rpm
sh-3.2# rpm -i libhdf5-101-1.10.1-3.85.aarch64.rpm
sh-3.2# rpm -i libhdf5_cpp101-1.10.1-3.85.aarch64.rpm
There may be message like this but it seems OK:
/sbin/ldconfig: Cannot lstat /lib64/libhdf5.so.101.0.0: Permission denied
Continue install
sh-3.2# rpm -i nnfw-1.10.0-1.aarch64.rpm
sh-3.2# rpm -i nnfw-test-1.10.0-1.aarch64.rpm
Our Product binary folder is installed at /opt/usr/nnfw-test.
sh-3.2# cd /opt/usr/nnfw-test
sh-3.2# ls -al
total 16
drwxr-xr-x 4 root root 4096 Jan 1 09:05 .

(6) Run nnpackage
Refer how-to-build-package.md document to produce nnpackage from a model.
Assume mobilenet_v2_1.4_224 nnpackage is already copied to /opt/usr/home/owner/media/models folder with sdb command.
sh-3.2# BACKENDS="cpu" Product/out/bin/onert_run \
/opt/usr/home/owner/media/models/mobilenet_v2_1.4_224
Package Filename /opt/usr/home/owner/media/models/mobilenet_v2_1.4_224
