Robert Sipka 9043ec620d Add debugger support on nuttx-smt32f4 target (#1591) 
Using jerry_parse_named_resource to parse script and construct an EcmaScript function.
The file name will also passed to this function which is used by the debugger to find
the source code.
Run the constructed EcmaScript function instead of using the simple jerry runner.

About

This folder contains files to run JerryScript on STM32F4-Discovery board with NuttX

How to build

1. Setting up the build environment for STM32F4-Discovery board

Clone JerryScript and NuttX into jerry-nuttx directory

mkdir jerry-nuttx
cd jerry-nuttx
git clone https://github.com/jerryscript-project/jerryscript.git
git clone https://bitbucket.org/nuttx/nuttx.git
git clone https://bitbucket.org/nuttx/apps.git
git clone https://github.com/texane/stlink.git

The following directory structure is created after these commands

jerry-nuttx
  + apps
  + jerryscript
  |  + targets
  |      + nuttx-stm32f4
  + nuttx
  + stlink

2. Adding JerryScript as an interpreter for NuttX

cd apps/interpreters
mkdir jerryscript
cp ../../jerryscript/targets/nuttx-stm32f4/* ./jerryscript/

3. Configure NuttX

# assuming you are in jerry-nuttx folder
cd nuttx/tools

# configure NuttX USB console shell
./configure.sh stm32f4discovery/usbnsh

cd ..
# might require to run "make menuconfig" twice
make menuconfig

We must set the following options:

  • Change Build Setup -> Build Host Platform from Windows to Linux
  • Enable System Type -> FPU support
  • Enable Library Routines -> Standard Math library
  • Enable Application Configuration -> Interpreters -> JerryScript

If you get kconfig-mconf: not found error when you run make menuconfig you may have to install kconfig-frontends:

# assume you are in jerry-nuttx folder
sudo apt-get install gperf flex bison libncurses-dev
git clone https://github.com/jameswalmsley/kconfig-frontends.git
cd kconfig-frontends
./bootstrap
./configure --enable-mconf
make
sudo make install
sudo ldconfig

4. Build JerryScript for NuttX

# assuming you are in jerry-nuttx folder
cd nuttx/
make

5. Flashing

Connect Mini-USB for power supply and connect Micro-USB for NSH console.

To configure stlink utility for flashing, follow the instructions here.

To flash,

# assuming you are in nuttx folder
sudo ../stlink/build/st-flash write nuttx.bin 0x8000000

Running JerryScript

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

sudo minicom --device=/dev/ttyACM0 --baud=115200

You may have to press RESET on the board and press Enter keys on the console several times to make nsh prompt to appear.

If the prompt shows like this,

NuttShell (NSH)
               nsh>
                    nsh>
                         nsh>

please set Add Carriage Ret option by CTRL-A > Z > U at the console, if you're using minicom.

Run jerry with javascript file(s)

NuttShell (NSH)
nsh> jerry full_path/any.js

Without argument it prints:

nsh> jerry
No input files, running a hello world demo:
Hello world 5 times from JerryScript
