Fixes issue #2094, which introduced an error caused by jerry_value_is_syntax_error. The problem was that the function used strcmp instead of strncmp while checking if err_str_buf contains syntax error and it caused buffer overflow.

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 Platformfrom Windows to Linux - Enable
System Type -> FPU support - 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 in the official Stlink repository.
To flash,
# assuming you are in nuttx folder
sudo ../stlink/build/Release/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
