# JerryScript with mbed OS 5
TL;DR? jump straight to [quickstart](#quick-start)
## Introduction
This directory contains the necessary code to build JerryScript for devices
capable of running mbed OS 5. It has been tested with the following boards
so far:
- [Nordic Semiconductor NRF52 Development Kit](https://developer.mbed.org/platforms/Nordic-nRF52-DK/)
- [NXP Freedom K64F](https://developer.mbed.org/platforms/FRDM-K64F/)
- [STM NUCLEO F401RE](https://developer.mbed.org/platforms/ST-Nucleo-F401RE/)
- [Silicon Labs EFM32 Giant Gecko](https://developer.mbed.org/platforms/EFM32-Giant-Gecko/)
## Features
### Peripheral Drivers
Peripheral Drivers are intended as a 1-to-1 mapping to mbed C++ APIs, with a few
differences (due to differences between JavaScript and C++ like lack of operator
overloading).
- [DigitalOut](https://docs.mbed.com/docs/mbed-os-api-reference/en/5.1/APIs/io/DigitalOut/)
- [InterruptIn](https://docs.mbed.com/docs/mbed-os-api-reference/en/5.1/APIs/io/InterruptIn/)
- [I2C](https://docs.mbed.com/docs/mbed-os-api-reference/en/5.1/APIs/interfaces/digital/I2C/)
- setInterval and setTimeout using [mbed-event](https://github.com/ARMmbed/mbed-events)
## Dependencies
### mbed CLI
mbed CLI is used as the build tool for mbed OS 5. You can find out how to install
it in the [official documentation](https://docs.mbed.com/docs/mbed-os-handbook/en/5.1/dev_tools/cli/#installing-mbed-cli).
### arm-none-eabi-gcc
arm-none-eabi-gcc is the only currently tested compiler for jerryscript on mbed,
and instructions for building can be found as part of the mbed-cli installation
instructions above.
### make
make is used to automate the process of fetching dependencies, and making sure that
mbed-cli is called with the correct arguments.
### nodejs
npm is used to install the dependencies in the local node_modules folder.
### gulp
gulp is used to automate tasks, like cloning repositories or generate source files.
If you create an own project, for more info see [mbed-js-gulp](https://github.com/ARMmbed/mbed-js-gulp).
### (optional) jshint
jshint is used to statically check your JavaScript code, as part of the build process.
This ensures that pins you are using in your code are available on your chosen target
platform.
## Quick Start
Once you have all of your dependencies installed, you can build the example project as follows:
```bash
git clone https://github.com/ARMmbed/mbed-js-example
cd mbed-js-example
npm install
gulp --target=YOUR_TARGET_NAME
```
The produced file (in build/out/YOUR_TARGET_NAME) can then be uploaded to your board, and will
run when you press reset.

### About
This folder contains files to run JerryScript on
[STM32F4-Discovery board](https://www.st.com/en/evaluation-tools/stm32f4discovery.html) with
[NuttX](https://nuttx.apache.org/).
The document had been validated on Ubuntu 20.04 operating system.
### How to build
#### 1. Setup the build environment for STM32F4-Discovery board
Clone the necessary projects into a `jerry-nuttx` directory.
The latest tested working version of NuttX is 10.2.
```sh
# Create a base folder for all the projects.
mkdir jerry-nuttx && cd jerry-nuttx
git clone https://github.com/jerryscript-project/jerryscript.git
git clone https://github.com/apache/incubator-nuttx.git nuttx -b releases/10.2
git clone https://github.com/apache/incubator-nuttx-apps.git apps -b releases/10.2
git clone https://bitbucket.org/nuttx/tools.git tools
git clone https://github.com/texane/stlink.git -b v1.5.1-patch
```
The following directory structure is created after these commands:
```
jerry-nuttx
+ jerryscript
| + targets
| + os
| + nuttx
+ nuttx
+ apps
+ tools
+ stlink
```
#### 2. Install dependencies of the projects
```sh
# Assuming you are in jerry-nuttx folder.
jerryscript/tools/apt-get-install-deps.sh
# Toolchain dependencies of NuttX.
sudo apt install gcc-arm-none-eabi binutils-arm-none-eabi
# Tool dependencies of NuttX.
sudo apt install \
bison flex gettext texinfo libncurses5-dev libncursesw5-dev \
gperf automake libtool pkg-config build-essential gperf genromfs \
libgmp-dev libmpc-dev libmpfr-dev libisl-dev binutils-dev libelf-dev \
libexpat-dev gcc-multilib g++-multilib picocom u-boot-tools util-linux
# ST-Link and serial communication dependencies.
sudo apt install libusb-1.0-0-dev minicom
```
#### 3. Copy JerryScript's application files to NuttX
Move JerryScript application files to `apps/interpreters/jerryscript` folder.
```sh
# Assuming you are in jerry-nuttx folder.
mkdir -p apps/interpreters/jerryscript
cp jerryscript/targets/os/nuttx/* apps/interpreters/jerryscript/
# Or more simply:
# ln -s jerryscript/targets/os/nuttx apps/interpreters/jerryscript
```
#### 4. Build kconfig-frontend to configure NuttX
Skip this section if `kconfig-frontends` had alrady been installed by package manager.
```sh
# Assuming you are in jerry-nuttx folder.
cd tools/kconfig-frontends
./configure \
--disable-nconf \
--disable-gconf \
--disable-qconf \
--disable-shared \
--enable-static \
--prefix=${PWD}/install
make
make install
# Add install folder to PATH
PATH=${PWD}/install/bin:$PATH
```
#### 5. Configure NuttX
Configure NuttX for serial communication. A `.config` file contains all the options for the build.
```sh
# Assuming you are in jerry-nuttx folder.
cd nuttx/tools
# Configure NuttX to use USB console shell.
./configure.sh stm32f4discovery:usbnsh
```
By default, JerryScript is disabled so it is needed to modify the configuration file. It can
be done by using menuconfig (section 5.1) or modifying the `.config` file directly (section 5.2).
##### 5.1 Enable JerryScript using menuconfig
```sh
# Assuming you are in jerry-nuttx folder.
# Might be required to run `make menuconfig` twice.
make -C nuttx menuconfig
```
* Enable `System Type -> FPU support`
* Enable `Application Configuration -> Interpreters -> JerryScript`
[Optional] Enabling ROMFS helps to flash JavaScript input files to the device's flash memory.
* Enable `File systems -> ROMFS file system`
* Enable `Application configuration -> NSH library -> Scripting Support -> Support ROMFS start-up script`
[Optional] Enabling MMCSD helps to mount sd card on the device.
Note: These options are for the micro-sd card slot of STM32F4-Discovery base-board.
* Enable `System Type -> STM32 Peripheral Support -> SDIO`
* Enable `RTOS Features -> Work queue support -> High priority (kernel) worker thread`
* Enable `RTOS Features -> RTOS hooks -> Custom board late initialization`
* Enable `Driver Support -> MMC/SD Driver Support`
* Disable `Driver Support -> MMC/SD Driver Support -> MMC/SD write protect pin`
* Disable `Driver Support -> MMC/SD Driver Support -> MMC/SD SPI transfer support`
* Enable `Driver Support -> MMC/SD Driver Support -> MMC/SD SDIO transfer support`
* Enable `File systems -> FAT file system`
* Enable `File systems -> FAT file system -> FAT upper/lower names`
* Enable `File systems -> FAT file system -> FAT long file names`
##### 5.2 Enable JerryScript without user interaction
A simpler solution is to append the necessary content to the `.config` configuration file:
```sh
# Assuming you are in jerry-nuttx folder.
cat >> nuttx/.config << EOL
CONFIG_ARCH_FPU=y
CONFIG_INTERPRETERS_JERRYSCRIPT=y
CONFIG_INTERPRETERS_JERRYSCRIPT_PRIORITY=100
CONFIG_INTERPRETERS_JERRYSCRIPT_STACKSIZE=16384
EOL
```
[Optional] Enable ROM File System
```sh
# Assuming you are in jerry-nuttx folder.
cat >> nuttx/.config << EOL
CONFIG_BOARDCTL_ROMDISK=y
CONFIG_FS_ROMFS=y
CONFIG_NSH_ROMFSETC=y
CONFIG_NSH_ROMFSMOUNTPT="/etc"
CONFIG_NSH_INITSCRIPT="init.d/rcS"
CONFIG_NSH_ROMFSDEVNO=0
CONFIG_NSH_ROMFSSECTSIZE=64
CONFIG_NSH_DEFAULTROMFS=y
EOL
```
[Optional] Enable MMCSD driver and FAT File System
Note: These options are for the micro-sd card slot of STM32F4-Discovery base-board.
```sh
# Assuming you are in jerry-nuttx folder.
cat >> nuttx/.config << EOL
CONFIG_STM32_SDIO=y
CONFIG_STM32_SDIO_DMAPRIO=0x00010000
CONFIG_MMCSD_HAVE_CARDDETECT=y
CONFIG_BOARD_LATE_INITIALIZE=y
CONFIG_BOARD_INITTHREAD_STACKSIZE=2048
CONFIG_BOARD_INITTHREAD_PRIORITY=240
CONFIG_SIG_SIGWORK=17
CONFIG_SCHED_WORKQUEUE=y
CONFIG_SCHED_HPWORK=y
CONFIG_SCHED_HPNTHREADS=1
CONFIG_SCHED_HPWORKPRIORITY=224
CONFIG_SCHED_HPWORKSTACKSIZE=2048
CONFIG_BCH=y
CONFIG_ARCH_HAVE_SDIO=y
CONFIG_ARCH_HAVE_SDIOWAIT_WRCOMPLETE=y
CONFIG_ARCH_HAVE_SDIO_PREFLIGHT=y
CONFIG_MMCSD=y
CONFIG_MMCSD_NSLOTS=1
CONFIG_MMCSD_MMCSUPPORT=y
CONFIG_MMCSD_SDIO=y
CONFIG_FS_FAT=y
CONFIG_FAT_LCNAMES=y
CONFIG_FAT_LFN=y
CONFIG_FAT_MAXFNAME=32
CONFIG_FAT_LFN_ALIAS_TRAILCHARS=0
CONFIG_FSUTILS_MKFATFS=y
CONFIG_NSH_MMCSDSLOTNO=0
EOL
```
#### 6. Provide JavaScript files for STM32F4 device
##### 6.1. Create ROMFS image from a custom folder
Skip this section if MMCSD is used. Otherwise, generate a C header file from a custom folder.
Try to minimize the size of the folder due to the limited capacity of flash memory.
```sh
# Assuming you are in jerry-nuttx folder.
mkdir jerry-example
# Let hello.js be a possible JavaScript input for JerryScript.
cp jerryscript/tests/hello.js jerry-example
# Generate ROMFS image from a custom folder.
genromfs -f romfs_img -d jerry-example
# Dump image as C header file and override NuttX's default ROMFS file.
xxd -i romfs_img apps/nshlib/nsh_romfsimg.h
# Add const modifier to place the content to flash memory.
sed -i "s/unsigned/const\ unsigned/g" apps/nshlib/nsh_romfsimg.h
```
##### 6.2. Copy files to memory card
Skip this section if ROMFS is used. Otherwise, copy your files to a FAT32 formatted memory card.
#### 7. Build NuttX (with JerryScript)
```sh
# Assuming you are in jerry-nuttx folder.
make -C nuttx
```
#### 8. Flash the device
Connect Mini-USB for charging and flasing the device.
```sh
# Assuming you are in jerry-nuttx folder.
make -C stlink release
sudo stlink/build/Release/st-flash write nuttx/nuttx.bin 0x8000000
```
#### 9. Connect to the device
Connect Micro-USB for serial communication. 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.
You may have to press `RESET` on the board and press `Enter` key on the console several times to make `nsh` prompt visible.
NuttShell (NSH) prompt looks like as follows:
```
NuttShell (NSH) NuttX-10.2.0
nsh>
```
#### 10. Run JerryScript
##### 10.1 Run `jerry` without input
```
NuttShell (NSH) NuttX-10.2.0
nsh> jerry
No input files, running a hello world demo:
Hello world 5 times from JerryScript
```
##### 10.2 Run `jerry` with files from ROMFS
```
NuttShell (NSH) NuttX-10.2.0
nsh> jerry /etc/hello.js
```
##### 10.3 Run `jerry` with files from memory card
After NuttX has initialized, the card reader should be visible as `/dev/mmcsd0` on the device.
Mount it to be JavaScript files reachable.
```
NuttShell (NSH) NuttX-10.2.0
nsh> mount -t vfat /dev/mmcsd0 /mnt
nsh> jerry /mnt/hello.js
```

# JerryScript for OpenWrt build guide
This document describes the steps required to compile the JerryScript
for OpenWrt. For target device the TP-Link WR1043ND v1.x router is
used. Please be advised, that if you have a different one minor
modifications to this document could be required.
IMPORTANT!
As the TP-Link WR1043ND is a mips based device and mips is a big-endian
architecture a JerryScript snapshot which was built on an little-endian
system will not work correctly. Thus it is advised that the
snapshot functionally should be used with caution, that is
DO NOT run snapshots generated on little-endian system(s) on
a big-endian system.
## OpenWrt notes
In 2018 ~January the OpenWrt and LEDE project merged into one
and thus the old OpenWrt parts are now usable only from
an archived repository: https://github.com/openwrt/archive
## OpenWrt toolchain setup
To build the JerryScript for OpenWrt a toolchain is required for
the target router/device. The toolchain setup in this document was
tested on an Ubuntu 16.04.3 LTS Linux.
Steps required for toolchain creation:
### 0. Install OpenWrt build requirements
```sh
$ sudo apt-get install git-core build-essential libssl-dev libncurses5-dev unzip gawk zlib1g-dev subversion mercurial
```
### 1. Clone OpenWrt (Chaos Calmer version)
```sh
$ git clone https://github.com/openwrt/archive openwrt -b chaos_calmer
$ cd openwrt
```
### 2. Run Menuconfig and configure the OpenWrt
```sh
$ make menuconfig
```
Options which should be set:
* Set "Target System" to "Atheros AR7xxx/AR9xxx".
* Set "Target Profile" to "TP-LINK TL-WR1043N/ND".
Save the configuration (as .config) and exit from the menuconfig.
### 3. Configure the environment variables
```sh
$ export BUILDROOT=$(pwd) # where the openwrt root dir is
$ export STAGING_DIR=${BUILDROOT}/staging_dir/ # required by the compiler
$ export PATH=$PATH:${STAGING_DIR}/host/bin:${STAGING_DIR}/toolchain-mips_34kc_gcc-4.8-linaro_uClibc-0.9.33.2/bin/
```
The name `toolchain-mips_34kc_gcc-4.8-linaro_uClibc-0.9.33.2` is created based on the menuconfig.
This changes depending on the target device!
### 4. Build the OpenWrt
```sh
$ make
```
### 5. Check if the compiler was built
```sh
$ mips-openwrt-linux-gcc --version # running this should print out the version information
```
At this point we have the required compiler for OpenWrt.
## Build JerryScript for OpenWrt
### 0. Check environment
Please check if the `STAGING_DIR` is configured correctly and that the toolchain binary is on the `PATH`.
### 1. Run the build with the OpenWrt toolchain file
```
$ ./tools/build.py --toolchain cmake/toolchain_openwrt_mips.cmake \
--lto OFF
```
### 2. Copy the binary
After a successful build the `build/bin/jerry` binary file can be copied to the target device.
On how to copy a binary file to an OpenWrt target device please see the OpenWrt manual(s).

### About
This folder contains files to run JerryScript on
[STM32F4-Discovery board](https://www.st.com/en/evaluation-tools/stm32f4discovery.html) with
[RIOT](https://www.riot-os.org/).
The document had been validated on Ubuntu 20.04 operating system.
### How to build
#### 1. Setup the build environment for STM32F4-Discovery board
Clone the necessary projects into a `jerry-riot` directory.
The latest tested working version of RIOT is `2021.10`.
```sh
# Create a base folder for all the projects.
mkdir jerry-riot && cd jerry-riot
git clone https://github.com/jerryscript-project/jerryscript.git
git clone https://github.com/RIOT-OS/RIOT.git -b 2021.10
```
#### 2. Install dependencies of the projects
```
# Assuming you are in jerry-riot folder.
jerryscript/tools/apt-get-install-deps.sh
sudo apt install gcc-arm-none-eabi openocd minicom
```
The following directory structure has been created:
```
jerry-riot
+ jerryscript
| + targets
| + os
| + riot
+ RIOT
```
#### 3. Build RIOT (with JerryScript)
```
# Assuming you are in jerry-riot folder.
make BOARD=stm32f4discovery -f jerryscript/targets/os/riot/Makefile
```
The created binary is a `riot_jerryscript.elf` named file located in `jerryscript/build/riot-stm32f4/bin/` folder.
#### 4. Flash the device
Connect Mini-USB for charging and flashing the device.
```
# Assuming you are in jerry-riot folder.
make BOARD=stm32f4discovery -f jerryscript/targets/os/riot/Makefile flash
```
Note: `ST-LINK` also can be used that is described at [this page](https://github.com/RIOT-OS/RIOT/wiki/ST-LINK-tool).
#### 5. Connect to the device
Use `USB To TTL Serial Converter` for serial communication. STM32F4-Discovery pins are mapped by RIOT as follows:
```
STM32f4-Discovery PA2 pin is configured for TX.
STM32f4-Discovery PA3 pin is configured for RX.
```
* Connect `STM32f4-Discovery` **PA2** pin to **RX** pin of `USB To TTL Serial Converter`
* Connect `STM32f4-Discovery` **PA3** pin to **TX** pin of `USB To TTL Serial Converter`
* Connect `STM32f4-Discovery` **GND** pin to **GND** pin of `USB To TTL Serial Converter`
The device should be visible as `/dev/ttyUSB0`. Use `minicom` communication program with `115200`.
* In `minicom`, set `Add Carriage Ret` to `off` in by `CTRL-A -> Z -> U` key combinations.
* In `minicom`, set `Hardware Flow Control` to `no` by `CTRL-A -> Z -> O -> Serial port setup -> F` key combinations.
```sh
sudo minicom --device=/dev/ttyUSB0 --baud=115200
```
RIOT prompt looks like as follows:
```
main(): This is RIOT! (Version: 2021.10)
You are running RIOT on a(n) stm32f4discovery board.
This board features a(n) stm32 MCU.
>
```
You may have to press `RESET` on the board and press `Enter` key on the console several times to make RIOT prompt visible.
#### 6. Run JerrySript
Type `help` to list shell commands:
```
> help
Command Description
---------------------------------------
test Jerryscript Hello World test
reboot Reboot the node
version Prints current RIOT_VERSION
pm interact with layered PM subsystem
```
Type `test` to execute JerryScript:
```
> test
This test run the following script code: [print ('Hello, World!');]
Hello, World!
```

### About
This folder contains files to run JerryScript on
[STM32F4-Discovery board](https://www.st.com/en/evaluation-tools/stm32f4discovery.html) with
[Zephyr](https://zephyrproject.org/).
The document had been validated on Ubuntu 20.04 operating system.
#### 1. Setup the build environment
Clone the necessary projects into a `jerry-zephyr` directory.
The latest tested working version of Zephyr is `v2.7.0`.
```sh
mkdir jerry-zephyr && cd jerry-zephyr
git clone https://github.com/jerryscript-project/jerryscript.git
git clone https://github.com/zephyrproject-rtos/zephyr -b v2.7.0
# Zephyr requires its toolchain.
wget https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.13.2/zephyr-toolchain-arm-0.13.2-linux-x86_64-setup.run
```
The following directory structure has been created:
```
jerry-zephyr
+ jerryscript
| + targets
| + os
| + zephyr
+ zephyr
+ zephyr-toolchain-arm-0.13.2-linux-x86_64-setup.run
```
#### 2. Install dependencies of the projects
```sh
# Assuming you are in jerry-zephyr folder.
jerryscript/tools/apt-get-install-deps.sh
# Tool dependencies of Zephyr.
sudo apt install --no-install-recommends \
git cmake ninja-build gperf ccache dfu-util device-tree-compiler \
python3-dev python3-pip python3-setuptools python3-tk python3-wheel \
xz-utils file make gcc gcc-multilib g++-multilib libsdl2-dev
# Install Python dependencies of Zephyr.
pip3 install --user -r zephyr/scripts/requirements.txt
# Install Zephyr toolchain.
chmod +x zephyr-toolchain-arm-0.13.2-linux-x86_64-setup.run
./zephyr-toolchain-arm-0.13.2-linux-x86_64-setup.run -- -y -d ${PWD}/zephyr-toolchain-0.13.2
```
Note: CMake 3.20 is required. If the installed CMake is older, upgrade it for example [this way](https://apt.kitware.com/).
#### 3. Initialize west meta-tool for Zephyr
```
# Assuming you are in jerry-zephyr folder.
west init -l zephyr
west update hal_stm32 cmsis
west zephyr-export
```
#### 4. Build Zephyr (with JerryScript)
```
# Assuming you are in jerry-zephyr folder.
west build -p auto -b stm32f4_disco jerryscript/targets/os/zephyr/
```
The created binary is a `zephyr.elf` named file located in `jerry-zephyr/build/zephyr/bin/` folder.
#### 5. Flash
Install `udev` rules which allows to flash STM32F4-Discovery as a regular user:
```
# Assuming you are in jerry-zephyr folder.
sudo cp zephyr-toolchain-0.13.2/sysroots/x86_64-pokysdk-linux/usr/share/openocd/contrib/60-openocd.rules /etc/udev/rules.d
sudo udevadm control --reload
```
Connect Mini-USB for charging and flasing the device.
```
# Assuming you are in jerry-zephyr folder.
west flash
```
#### 6. Connect to the device
Use `USB To TTL Serial Converter` for serial communication. STM32F4-Discovery pins are mapped by Zephyr as follows:
```
STM32f4-Discovery PA2 pin is configured for TX.
STM32f4-Discovery PA3 pin is configured for RX.
```
* Connect `STM32f4-Discovery` **PA2** pin to **RX** pin of `USB To TTL Serial Converter`
* Connect `STM32f4-Discovery` **PA3** pin to **TX** pin of `USB To TTL Serial Converter`
* Connect `STM32f4-Discovery` **GND** pin to **GND** pin of `USB To TTL Serial Converter`
The device should be visible as `/dev/ttyUSB0`. Use `minicom` communication program with `115200`.
* In `minicom`, set `Add Carriage Ret` to `off` in by `CTRL-A -> Z -> U` key combinations.
* In `minicom`, set `Hardware Flow Control` to `no` by `CTRL-A -> Z -> O -> Serial port setup -> F` key combinations.
```sh
sudo minicom --device=/dev/ttyUSB0 --baud=115200
```
Press `RESET` on the board to get the initial message with JerryScript command prompt:
```
*** Booting Zephyr OS build v2.7.99-1786-ga08b65ef42db ***
JerryScript build: Nov 25 2021 14:17:17
JerryScript API 3.0.0
Zephyr version 2.7.99
js>
```
Run the following JavaScript example:
```
js> var test = 0; for (t = 100; t < 1000; t++) test += t; print ('Hello World! ' + test);
Hello World! 494550
undefined
```
