### About
|
|
|
|
This folder contains files to run JerryScript on
|
|
[STM32F4-Discovery board](http://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-tools/stm32-mcu-eval-tools/stm32-mcu-discovery-kits/stm32f4discovery.html) with [NuttX](http://nuttx.org/)
|
|
|
|
### 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/Samsung/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
|
|
```
|
|
|
|
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"
|
|
|
|
#### 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](https://github.com/texane/stlink#build-from-sources).
|
|
|
|
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
|
|
```
