Build for ARTIK053 TizenRT

About

This directory contains files to run IoT.js on TizenRT.

How to build

1. Set up the build environment for Artik053 board

Install toolchain

Get the build in binaries and libraries, gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar.

Untar the gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar and export the path like

tar xvf gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar
export PATH=<Your Toolchain PATH>:$PATH

Install genromfs to use romfs

sudo apt-get install genromfs

Install kconfig-frontends to use menuconfig

Refer to Kconfig-frontends Installation

Get IoT.js and TizenRT sources

Clone IoT.js and TizenRT into iotjs-tizenrt directory

mkdir iotjs-tizenrt
cd iotjs-tizenrt
git clone https://github.com/Samsung/iotjs.git
git clone https://github.com/Samsung/TizenRT.git

The following directory structure is created after these commands

iotjs-tizenrt
  + iotjs
  + TizenRT

2. Configure IoT.js

This step is optional. You can edit the build config of IoT.js in iotjs/build.config. In order to enable modules you want, you can configure your own profile file, or you can add them as an option to the build command. For more details, please find the ENABLE_MODULE_[NAME] section in How to write a new module.

ENABLE_MODULE_ADC
ENABLE_MODULE_GPIO

$ ./tools/build.py --external-modules=./my-module --cmake-param=-DENABLE_MODULE_MYMODULE=ON

3. Configure TizenRT

cd TizenRT/os/tools
./configure.sh artik053/iotjs
cd ..

4. Copy your app in ROMFS

cp <your test app> ../tools/fs/contents/
# make ROMFS image
../tools/fs/mkromfsimg.sh
# The contents folder is later flashing into the target's /rom folder

NOTE: The romfs image file must not exceed 400kb.

5. Build IoT.js for TizenRT

make IOTJS_ROOT_DIR=../../iotjs

If IOTJS_ROOT_DIR isn't given as the argument, IoT.JS codes, which are located in external/iotjs of TizenRT, will be used for the build.

❕ Trouble Shooting: Building IoT.js fails: You may encounter arm-none-eabi-gcc: Command not found error message while building IoT.js on a 64-bit system. This may be because the above toolchain you set uses 32-bit libs. For this matter, install the below toolchain as alternative.

$ sudo apt-get install -y libc6-i386

6. Flashing

make download ALL

❕ Trouble Shooting: Flashing the binary via USB fails: Refer to add-usb-device-rules. Your VendorID:ProductID pair can be found in lsusb output as the below instance.

$ lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 005: ID 0403:6010 Future Technology Devices International, Ltd >FT2232C Dual USB-UART/FIFO IC

7. Run IoT.js

You should use minicom to login to the device.

$ sudo minicom -s

The following changes are necessaries in the Serial port setup menu:

Serial Device         : /dev/<device-id>      # e.g. /dev/ttyUSB0
Hardware Flow Control : No

After Exit, press an enter and the prompt should be available:

TASH>>

The following commands help to establish Internet connection on the device:

TASH>> wifi startsta
TASH>> wifi join <ssid> <password>
TASH>> ifconfig wl1 dhcp

Finally, the iotjs built-in command can be executed:

TASH>> iotjs
Usage: iotjs [options] {FILE | FILE.js} [arguments]
TASH>>
