This folder contains files to run JerryScript in mbed / for:
|
||||
|
||||
* Freedom-K64F (k64)
|
||||
* Discovery-STM32F4 (stm32f4)
|
||||
* Discovery-STM32F429ZI (stm32f429i)
|
||||
* Nucleo-F401RE (nucleo)
|
||||
|
||||
####Yotta
|
||||
You need to install yotta before proceeding. Please visit [Yotta docs page](http://yottadocs.mbed.com/#installing-on-linux).
|
||||
|
||||
####Cross-compiler
|
||||
For cross-compilation the GCC 5.2.1 is suggested to be used. All the supported targets were tested with this version. If you don't have any GCC compiler installed, please visit [this](https://launchpad.net/gcc-arm-embedded/+download) page to download GCC 5.2.1.
|
||||
|
||||
####How to build a target
|
||||
Navigate to your JerryScript root folder (after you cloned this repository into the targets folder) and use the following command:
|
||||
|
||||
```
|
||||
make -f targets/target-mbed/Makefile.mbed board=$(TARGET)
|
||||
```
|
||||
Where the `$(TARGET)` is one of the following options: `k64f`, `stm32f4`, `stm32f429i` or `nucleo`.
|
||||
This command will create a new folder for your target and build the jerryscript and mbed OS into that folder.
|
||||
|
||||
####How to build a completely new target
|
||||
If you want to build a new target (which is not available in this folder) you have to modify the makefile.
|
||||
You have to add the new board name to the `TARGET_LIST` and you have to add a new branch with the new `YOTTA_TARGET` and a new `TARGET_DIR` path (if it neccessary) to the if at the top in the Makefile (just as you see right now).
|
||||
There is a little code snippet:
|
||||
|
||||
```
|
||||
ifeq ($(TARGET), k64f)
|
||||
YOTTA_TARGET = frdm-k64f-gcc
|
||||
TARGET_DIR ?= /media/$(USER)/MBED
|
||||
else ifeq ($(TARGET), stm32f4)
|
||||
YOTTA_TARGET =
|
||||
```
|
||||
|
||||
Basically, you can create a new target in this way (If the mbed OS support your board).
|
||||
|
||||
#####Let's get into the details!
|
||||
1. The next rule is the `jerry` rule. This rule builds the JerryScript and copy the output files into the target libjerry folder. Two files will be generated at `targets/mbed$(TARGET)/libjerry`:
|
||||
* libjerrycore.a
|
||||
* libfdlibm.a
|
||||
|
||||
You can run this rule with the following command:
|
||||
- `make -f targets/target-mbed/Makefile.mbed board=$(TARGET) jerry`
|
||||
|
||||
2. The next rule is the `js2c`. This rule calls a `js2c.py` python script from the `jerryscript/targets/tools` and creates the JavaScript builtin file into the `targets/mbed$(TARGET)/source/` folder. This file is the `jerry_targetjs.h`. You can run this rule with the follwoing command:
|
||||
|
||||
- `make -f targets/target-mbed/Makefile.mbed board=$(TARGET) js2c`
|
||||
|
||||
3. The last rule is the `yotta`. This rule sets the yotta target and install the mbed-drivers module, install the dependencies for the mbed OS and finaly creates the mbed binary file. The binary file will be genrated at `targets/mbed$(TARGET)/build/$(YOTTA_TARGET)/source/jerry.bin`. You can run this rule with the following command:
|
||||
|
||||
- `make -f targets/target-mbed/Makefile.mbed board=$(TARGET) yotta`
|
||||
|
||||
4. Optional rule: `clean`. It removes the build folder from the target-mbed and jerry. You can run this rule with this command:
|
||||
|
||||
- `make -f targets/target-mbed/Makefile.mbed board=$(TARGET) clean`
|
||||
|
||||
#####Flashing
|
||||
When the build is finished you can flash the binary into your board if you want. In case of ST boards you have to install the `st-link` software. Please visit [this page](https://github.com/texane/stlink) to install STLink-v2.
|
||||
You can flash your binary into your board with the following command:
|
||||
```
|
||||
make -f targets/target-mbed/Makefile.mbed board=$(TARGET) flash
|
||||
```
|
||||
The flash rule grabs the binary and copies it to the mounted board or use the STLink-v2 to flash.
|
||||
When the status LED of the board stops blinking, press RESET button on the board to execute JerryScript led flashing sample program in js folder.
|
||||
|
||||
###Note
|
||||
If you use an STM32F4 board your build will stop with missing header errors. To fix this error please visit to [this page](http://browser.sed.hu/blog/20160407/how-run-javascripts-jerryscript-mbed) and read about the fix in the `New target for STM32F4` block.

### About
|
||||
|
||||
This folder contains files to run JerryScript in mbed / FRDM-K64F board.
|
||||
|
||||
#### Installing yotta
|
||||
|
||||
You need to install yotta before proceeding.
|
||||
Please visit http://yottadocs.mbed.com/#installing-on-linux
|
||||
|
||||
##### Cross-compiler for FRDM-K64F
|
||||
|
||||
If you don't have any GCC compiler installed, please visit [this]
|
||||
(https://launchpad.net/gcc-arm-embedded/+download) page to download GCC 4.8.4
|
||||
which was tested for building JerryScript for K64F.
|
||||
|
||||
#### How to build JerryScript
|
||||
|
||||
```
|
||||
make -f targets/mbedk64f/Makefile.mbedk64f clean
|
||||
make -f targets/mbedk64f/Makefile.mbedk64f jerry
|
||||
```
|
||||
|
||||
#### JerryScript output files
|
||||
|
||||
Two files will be generated at `targets/mbedk64f/libjerry`
|
||||
* libjerrycore.a
|
||||
* libjerrylibm.a
|
||||
|
||||
#### Building mbed binary
|
||||
|
||||
```
|
||||
make -f targets/mbedk64f/Makefile.mbedk64f js2c yotta
|
||||
```
|
||||
|
||||
Or, cd to `targets/mbedk64f` where `Makefile.mbedk64f` exist
|
||||
|
||||
```
|
||||
cd targets/mbedk64f
|
||||
yotta target frdm-k64f-gcc
|
||||
yotta build
|
||||
```
|
||||
|
||||
#### Build at once
|
||||
|
||||
Omit target name to build both jerry library and mbed binary.
|
||||
|
||||
```
|
||||
make -f targets/mbedk64f/Makefile.mbedk64f
|
||||
```
|
||||
|
||||
#### Flashing to k64f
|
||||
|
||||
|
||||
```
|
||||
make -f targets/mbedk64f/Makefile.mbedk64f flash
|
||||
```
|
||||
|
||||
It assumes default mound folder is `/media/(user)/MBED`
|
||||
|
||||
If its mounted to other path, give it with `TARGET_DIR` variable, for example,
|
||||
```
|
||||
TARGET_DIR=/mnt/media/MBED make -f targets/mbedk64f/Makefile.mbedk64f flash
|
||||
```
|
||||
|
||||
Or you can just copy `targets/mbedk64f/build/frdm-k64f-gcc/source/jerry.bin`
|
||||
file to mounted folder.
|
||||
|
||||
When LED near the USB port flashing stops and `MBED` folder shows up on the
|
||||
desktop(if you are using GUI), press RESET button on the board to execute
|
||||
JerryScript led flashing sample program in js folder.
|
||||
|
||||
#### How blink sample program works
|
||||
|
||||
All `.js` files in `js` folder are executed, with `main.js` in first order.
|
||||
`sysloop()` function in main.js is called periodically in every 100msec by
|
||||
below code in `main.c` `jerry_loop()`, which calls `js_loop()` in
|
||||
`jerry_mbedk64f.c`
|
||||
|
||||
```
|
||||
minar::Scheduler::postCallback(jerry_loop)
|
||||
.period(minar::milliseconds(100))
|
||||
```
|
||||
|
||||
`sysloop()` then calls `blink()` in `blink.js` which blinks the `LED` in
|
||||
every second.
