RT-Thread Lab

RT-Thread is an open source IoT operating system from China.

• RT-Thread Homepage
• RT-Thread Git Repo

To easier the learning and development of RT-Thread, this lab is added as a plugin of Cloud Lab.

The following sections introduce the using of RT-Thread on Qemu with Cloud Lab:

• RT-Thread Lab Homepage
• RT-Thread Lab Demo

Install Docker

Docker is required by RT-Thread Lab, please install it at first:

• Linux, Mac OSX, Windows 10: Docker CE
• Older Windows: Docker Toolbox

Notes:

In order to run docker without password, please make sure your user is added in the docker group:

$ sudo usermod -aG docker $USER

In order to speedup docker images downloading, please configure a local docker mirror in /etc/default/docker, for example:

$ grep registry-mirror /etc/default/docker
DOCKER_OPTS="$DOCKER_OPTS --registry-mirror=https://docker.mirrors.ustc.edu.cn"
$ service docker restart

In order to avoid network ip address conflict, please try following changes and restart docker:

$ grep bip /etc/default/docker
DOCKER_OPTS="$DOCKER_OPTS --bip=10.66.0.10/16"
$ service docker restart

If the above changes not work, try something as following:

$ grep dockerd /lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd -H fd:// --bip=10.66.0.10/16 --registry-mirror=https://docker.mirrors.ustc.edu.cn
$ service docker restart

For Ubuntu 12.04, please install the new kernel at first, otherwise, docker will not work:

$ sudo apt-get install linux-generic-lts-trusty

Choose a working directory

If installed via Docker Toolbox, please enter into the /mnt/sda1 directory of the default system on Virtualbox, otherwise, after poweroff, the data will be lost for the default /root directory is only mounted in DRAM.

$ cd /mnt/sda1

For Linux or Mac OSX, please simply choose one directory in ~/Downloads or ~/Documents.

$ cd ~/Documents

Download the lab

Use Ubuntu system as an example:

Download cloud lab framework, pull images and checkout rtthread-lab repository:

$ git clone https://github.com/tinyclub/cloud-lab.git
$ cd cloud-lab/ && tools/docker/choose rtthread-lab

Run and login the lab

Launch the lab and login with the user and password printed in the console:

$ tools/docker/run rtthread-lab

Re-login the lab via web browser:

$ tools/docker/vnc rtthread-lab

Use the lab

After login, Open 'RT-Thread Lab' in the desktop and it will enter into the working directory: /labs/rtthread-lab/,

Update source code

$ make init

Checkout the verified commit

$ pushd rt-thread
$ git checkout d629a3c87f
$ git clean -fdx
$ popd

Configure rt-thread

$ make config

Build rt-thread for qemu-vexpress-a9

$ make build

Boot it on qemu without graphic

$ make boot

Boot in on qemu with graphic

After booting, switch to the 4th terminal via CTRL+ALT+4:

$ make boot G=1

Configure network

Get host ip:

$ ifconfig br0 | grep inet
      inet addr:172.17.217.83  Bcast:172.17.255.255  Mask:255.255.0.0

Configure guest ip as a random static ip address with br0 ip as the gateway:

msh /> ifconfig e0 172.17.217.168 172.17.217.83 255.255.255.0
config : e0
IP addr: 172.17.217.168
Gateway: 172.17.217.83
netmask: 255.255.255.0

Ping from host to guest:

$ ping 172.17.217.168
