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 following commands:

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

Next, go to step 7

Build steps in detail

1. Set up build environment

• 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

• Get the jerryscript and TizenRT sources

$ mkdir jerry-tizenrt
$ cd jerry-tizenrt
$ git clone https://github.com/jerryscript-project/jerryscript.git
$ git clone https://github.com/Samsung/TizenRT.git -b 1.1_Public_Release

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/
$ cp jerryscript/targets/tizenrt-artik053/romfs-1.1.patch TizenRT/

3. Configure TizenRT

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

4. Configure TizenRT

$ cd ../../
$ patch -p1 < romfs-1.1.patch
$ cd build/output/
$ mkdir res
# You can add files in res folder
# The res folder is later flashing into the target's /rom folder
# CAUTION: You must not exceed 400kb

5. Build JerryScript for TizenRT

# assuming you are in jerry-tizenrt folder
jerryscript/tools/build.py \
    --clean \
    --lto=OFF \
    --jerry-cmdline=OFF \
    --jerry-libc=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

Note: 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

6. Build TizenRT binary

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

Binaries are available in TizenRT/build/output/bin

7. Generate romfs

$ genromfs -f ../build/output/bin/rom.img -d ../build/output/res/ -V "NuttXBootVol"

8. Flash binary

make download ALL

Reboot the device.

For more information, see How to program a binary.

9. Run JerryScript

You can use minicom for terminal program, or any other you may like, but set baud rate to 115200.

(Note: Device path may differ like /dev/ttyUSB1.)

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

Run jerry with javascript file(s)

TASH>>jerry hello.js                                                               
Hello JerryScript!

Without argument it prints:

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