### About
|
|
|
|
This folder contains files to run JerryScript on
|
|
[FRDM-K64F board](https://os.mbed.com/platforms/frdm-k64f/) with
|
|
[Mbed OS](https://os.mbed.com/).
|
|
The document had been validated on Ubuntu 20.04 operating system.
|
|
|
|
#### 1. Setup the build environment
|
|
|
|
Clone the necessary projects into a `jerry-mbedos` directory.
|
|
The latest tested working version of Mbed is `mbed-os-6.15.0`.
|
|
|
|
```sh
|
|
mkdir jerry-mbedos && cd jerry-mbedos
|
|
|
|
git clone https://github.com/jerryscript-project/jerryscript.git
|
|
git clone https://github.com/ARMmbed/mbed-os.git -b mbed-os-6.15.0
|
|
```
|
|
|
|
The following directory structure has been created:
|
|
|
|
```
|
|
jerry-mbedos
|
|
+ jerryscript
|
|
| + targets
|
|
| + os
|
|
| + mbedos
|
|
+ mbed-os
|
|
```
|
|
|
|
#### 2. Install dependencies of the projects
|
|
|
|
```sh
|
|
# Assuming you are in jerry-mbedos folder.
|
|
jerryscript/tools/apt-get-install-deps.sh
|
|
|
|
sudo apt install stlink-tools
|
|
pip install --user mbed-cli
|
|
# Install Python dependencies of Mbed OS.
|
|
pip install --user -r mbed-os/requirements.txt
|
|
```
|
|
|
|
#### 3. Build Mbed OS (with JerryScript)
|
|
|
|
```
|
|
# Assuming you are in jerry-mbedos folder.
|
|
make -C jerryscript/targets/os/mbedos MBED_OS_DIR=${PWD}/mbed-os
|
|
```
|
|
|
|
The created binary is a `mbedos.bin` named file located in `jerryscript/build/mbed-os` folder.
|
|
|
|
#### 4. Flash
|
|
|
|
Connect Micro-USB for charging and flashing the device.
|
|
|
|
```
|
|
# Assuming you are in jerry-mbedos folder.
|
|
make -C jerryscript/targets/os/mbedos MBED_OS_DIR=${PWD}/mbed-os flash
|
|
```
|
|
|
|
#### 5. Connect to the device
|
|
|
|
The device should be visible as `/dev/ttyACM0` on the host.
|
|
You can use `minicom` communication program with `115200` baud rate.
|
|
|
|
```sh
|
|
sudo minicom --device=/dev/ttyACM0 --baud=115200
|
|
```
|
|
|
|
Set `Add Carriage Ret` option in `minicom` by `CTRL-A -> Z -> U` key combinations.
|
|
Press `RESET` on the board to get the output of JerryScript application:
|
|
|
|
```
|
|
This test run the following script code: [print ('Hello, World!');]
|
|
|
|
Hello, World!
|
|
```
