### About
|
||||
|
||||
This folder contains files to run JerryScript on NuttX with
|
||||
[STM32F4-Discovery with BB](http://www.st.com/web/en/catalog/tools/FM116/SC959/SS1532/LN1199/PF255417)
|
||||
|
||||
|
||||
### How to build
|
||||
|
||||
#### 1. Preface
|
||||
|
||||
1, Directory structure
|
||||
|
||||
Assume `harmony` as the root folder to the projects to build.
|
||||
The folder tree related would look like this.
|
||||
|
||||
```
|
||||
harmony
|
||||
+ jerryscript
|
||||
| + targets
|
||||
| + nuttx-stm32f4
|
||||
+ nuttx
|
||||
| + nuttx
|
||||
| + lib
|
||||
+ st-link
|
||||
```
|
||||
|
||||
|
||||
2, Target board
|
||||
|
||||
Assume [STM32F4-Discovery with BB](http://www.st.com/web/en/catalog/tools/FM116/SC959/SS1532/LN1199/PF255417)
|
||||
as the target board.
|
||||
|
||||
|
||||
3, Micro SD-Card memory for Script source files
|
||||
|
||||
|
||||
#### 2. Prepare NuttX
|
||||
|
||||
Follow [this](https://bitbucket.org/seanshpark/nuttx/wiki/Home) page to get
|
||||
NuttX source and do the first build. When it stops with and error,
|
||||
change default project from `IoT.js` to `JerryScript` as follows;
|
||||
|
||||
2-1) run menuconfig
|
||||
```
|
||||
# assume you are in nuttx folder where .config exist
|
||||
make menuconfig
|
||||
```
|
||||
2-2) Select `Application Configuration` --> `Interpreters`
|
||||
|
||||
2-3) Check `[*] JerryScript interpreter` (Move cursor to the line and press `Space`)
|
||||
|
||||
2-4) `< Exit >` once on the bottom of the sceen (Press `Right arrow` and `Enter`)
|
||||
|
||||
2-5) Select `System Libraries and NSH Add-Ons`
|
||||
|
||||
2-6) Un-Check `[ ] iotjs program` (Move cursor to the line and press `Space`)
|
||||
|
||||
2-7) `< Exit >` till `menuconfig` ends. Save new configugation when asked.
|
||||
|
||||
2-7) `make` again
|
||||
```
|
||||
make
|
||||
```
|
||||
|
||||
It'll show the last error but it's ok. Nows the time to build JerryScript.
|
||||
|
||||
|
||||
#### 3. Build JerryScript for NuttX
|
||||
|
||||
```
|
||||
# assume you are in harmony folder
|
||||
cd jerryscript
|
||||
make -f ./targets/nuttx-stm32f4/Makefile.nuttx
|
||||
```
|
||||
|
||||
If you have NuttX at another path than described above, you can give the
|
||||
absolute path with `NUTTX` variable , for example,
|
||||
```
|
||||
NUTTX=/home/user/work/nuttx make -f ./targets/nuttx-stm32f4/Makefile.nuttx
|
||||
```
|
||||
|
||||
Make will copy three library files to `nuttx/nuttx/lib` folder
|
||||
```
|
||||
libjerryentry.a
|
||||
libjerrycore.a
|
||||
libfdlibm.a
|
||||
```
|
||||
|
||||
In NuttX, if you run `make clean`, above library files are also removed so you
|
||||
may have to build JerryScript again.
|
||||
|
||||
#### 4. Continue build NuttX
|
||||
|
||||
```
|
||||
# asssume you are in harmony folder
|
||||
cd nuttx/nuttx
|
||||
make
|
||||
```
|
||||
|
||||
|
||||
#### 5. Flashing
|
||||
|
||||
Connect Mini-USB for power supply and connect Micro-USB for `NSH` console.
|
||||
|
||||
Please refer [this](https://github.com/Samsung/iotjs/wiki/Build-for-NuttX#prepare-flashing-to-target-board)
|
||||
link to prepare `stlink` utility.
|
||||
|
||||
|
||||
To flash with `Makefile.nuttx`,
|
||||
```
|
||||
# assume you are in jerryscript folder
|
||||
make -f ./targets/nuttx-stm32f4/Makefile.nuttx flash
|
||||
```
|
||||
|
||||
#### 6. Cleaning
|
||||
|
||||
To clean the build result,
|
||||
```
|
||||
make -f ./targets/nuttx-stm32f4/Makefile.nuttx clean
|
||||
```
|
||||
|
||||
|
||||
### Running JerryScript
|
||||
|
||||
Prepare a micro SD-card and prepare `hello.js` like this in the root directory of SD-card.
|
||||
|
||||
```
|
||||
print("Hello JerryScript!");
|
||||
```
|
||||
|
||||
Power Off(unplug both USB cables), plug the memory card to BB, and power on again.
|
||||
|
||||
You can use `minicom` for terminal program, or any other you may like, but match
|
||||
baud rate to `115200`.
|
||||
|
||||
```
|
||||
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 `jerryscript` with `hello.js`
|
||||
|
||||
```
|
||||
NuttShell (NSH)
|
||||
nsh>
|
||||
nsh>
|
||||
nsh> jerryscript /mnt/sdcard/hello.js
|
||||
PARAM 1 : [/mnt/sdcard/hello.js]
|
||||
Hello JerryScript!
|
||||
```
|
||||
|
||||
Please give absolute path of the script file or may get an error like this.
|
||||
```
|
||||
nsh> cd /mnt/sdcard
|
||||
nsh> jerryscript ./hello.js
|
||||
PARAM 1 : [./hello.js]
|
||||
Failed to fopen [./hello.js]
|
||||
JERRY_STANDALONE_EXIT_CODE_FAIL
|
||||
nsh>
|
||||
nsh>
|
||||
nsh> jerryscript /mnt/sdcard/hello.js
|
||||
PARAM 1 : [/mnt/sdcard/hello.js]
|
||||
Hello JerryScript!
|
||||
