About

This folder contains files to build and run JerryScript on TizenRT with Artik053 board.

How to build

TL; DR

If you are in a hurry, run the following commands:

$ sudo apt-add-repository -y "ppa:team-gcc-arm-embedded/ppa"
$ sudo apt-get update
$ sudo apt-get install gcc-arm-embedded genromfs
$ git clone https://github.com/pando-project/jerryscript.git
$ cd jerryscript
$ make -f targets/tizenrt-artik053/Makefile.travis install
$ make -f targets/tizenrt-artik053/Makefile.travis script

Next, go to step 7

Build steps in detail

1. Set up build environment

• Install toolchain

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

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

• Get jerryscript and TizenRT sources.

$ mkdir jerry-tizenrt
$ cd jerry-tizenrt
$ git clone https://github.com/pando-project/jerryscript.git
$ git clone https://github.com/Samsung/TizenRT.git -b 2.0_Public_M2

The following directory structure is created after these commands:

jerry-tizenrt
  ├── jerryscript
  └── TizenRT

2. Add jerryscript configuration for TizenRT

$ cp -r jerryscript/targets/tizenrt-artik053/apps/jerryscript/ TizenRT/apps/system/
$ cp -r jerryscript/targets/tizenrt-artik053/configs/jerryscript/ TizenRT/build/configs/artik053/

3. Configure TizenRT

$ cd TizenRT/os/tools
$ ./configure.sh artik053/jerryscript

4. Build JerryScript for TizenRT

# assuming you are in jerry-tizenrt folder
jerryscript/tools/build.py \
    --clean \
    --lto=OFF \
    --jerry-cmdline=OFF \
    --all-in-one=OFF \
    --mem-heap=70 \
    --profile=es2015-subset \
    --compile-flag="--sysroot=${PWD}/TizenRT/os" \
    --toolchain=${PWD}/jerryscript/cmake/toolchain_mcu_artik053.cmake

Alternatively, there is a Makefile in the targets/tizenrt-artik053/ folder that also helps to build JerryScript for TizenRT.

# assuming you are in jerry-tizenrt folder
$ cd jerryscript
$ make -f targets/tizenrt-artik053/Makefile.tizenrt

5. Add your JavaScript program to TizenRT (optional)

If you have script files for JerryScript, you can add them to TizenRT. These files will be flashed into the target's /rom folder. Note that your content cannot exceed 1200 KB.

# assuming you are in jerry-tizenrt folder
cp jerryscript/tests/hello.js TizenRT/tools/fs/contents/

6. Build TizenRT binary

# assuming you are in jerry-tizenrt folder
$ cd TizenRT/os
$ make

Binaries are available in TizenRT/build/output/bin.

7. Flash binary

make download ALL

Reboot the device.

For more information, see How to program a binary.

8. Run JerryScript

Use a terminal program (e.g., minicom) with baud rate of 115200. (Note: Actual device path may vary, e.g., /dev/ttyUSB1.)

sudo minicom --device=/dev/ttyUSB0 --baud=115200

Run jerry with javascript file(s):

TASH>>jerry /rom/hello.js
Hello JerryScript!

Running the program without argument executes a built-in demo:

TASH>>jerry                                                                        
No input files, running a hello world demo:                                        
Hello World from JerryScript
