#### Apply patch to ESP8266 SDK
As `iram` is quite small to fit all the codes but linker tries to put it there.
To force JerryScript codes to be placed at the `irom` section,
need to change the order and tell the linker as below;
```

```
Second file is to modify `irom` size so that it can hold all the codes and data.
This can be done by giving another `SPI_SIZE_MAP`.
For now, I'll use this manual modification.
#### Need to get setjmp / longjmp
Extract and copy from the SDK.
```
cd ~/harmony/jerryscript/targets/esp8266/libs
ar -xv $SDK_PATH/lib/libcirom.a lib_a-setjmp.o
```

#### Preparation
##### Accessories
You need,
* 3.3V power supply. You can use bread board power (+5V, +3.3V). I used LM317 like this;
* Use [LM317](http://www.ti.com/lit/ds/symlink/lm317.pdf)
* R1 = 330 Ohm, R2 = 545 Ohm (1K + 1.2K in parallel)
* 5V 2A adaptor
* USB to RS-232 Serial + RS-232 Serial to Digital or USB-to-RS232 TTL converter
#### Toolchain
Reference [Toolchain](https://github.com/esp8266/esp8266-wiki/wiki/Toolchain) page.
I've slightly changed the step to use SDK from Espressif official SDK
(https://github.com/espressif/esp_iot_rtos_sdk)
##### Toolchain:
dependencies for x86
```
sudo apt-get install git autoconf build-essential gperf \
bison flex texinfo libtool libncurses5-dev wget \
gawk libc6-dev-i386 python-serial libexpat-dev
sudo mkdir /opt/Espressif
sudo chown $USER /opt/Espressif/
```
dependencies for x64
```
sudo apt-get install git autoconf build-essential gperf \
bison flex texinfo libtool libncurses5-dev wget \
gawk libc6-dev-amd64 python-serial libexpat-dev
sudo mkdir /opt/Espressif
sudo chown $USER /opt/Espressif/
```
crosstool-NG
```
cd /opt/Espressif
git clone -b lx106-g++-1.21.0 git://github.com/jcmvbkbc/crosstool-NG.git
cd crosstool-NG
./bootstrap && ./configure --prefix=`pwd` && make && make install
./ct-ng xtensa-lx106-elf
./ct-ng build
```
add path to environment file such as `.profile`
```
PATH=$PWD/builds/xtensa-lx106-elf/bin:$PATH
```
##### Espressif SDK: use Espressif official
```
cd /opt/Esprissif
git clone https://github.com/espressif/ESP8266_RTOS_SDK.git ESP8266_RTOS_SDK.git
ln -s ESP8266_RTOS_SDK.git ESP8266_SDK
cd ESP8266_SDK
git checkout -b jerry a2b413ad2996450fe2f173b6afab243f6e1249aa
```
We use SDK 1.2.0 version which has stdlib.h and others. Latest 1.3.0 version,
as of writing this document, doesn't have it.
(If anyone knows how to use latest version, please add an issue or send a PR.)
set two environment variables such as in .profile
```
export SDK_PATH=/opt/Espressif/ESP8266_SDK
export BIN_PATH=(to output folder path)
```
##### Xtensa libraries and headers:
```
cd /opt/Espressif/ESP8266_SDK
wget -O lib/libhal.a https://github.com/esp8266/esp8266-wiki/raw/master/libs/libhal.a
```
##### ESP image tool
```
cd /opt/Espressif
wget -O esptool_0.0.2-1_i386.deb https://github.com/esp8266/esp8266-wiki/raw/master/deb/esptool_0.0.2-1_i386.deb
sudo dpkg -i esptool_0.0.2-1_i386.deb
```
##### ESP upload tool
```
cd /opt/Espressif
git clone https://github.com/themadinventor/esptool esptool-py
sudo ln -s $PWD/esptool-py/esptool.py crosstool-NG/builds/xtensa-lx106-elf/bin/esptool.py
```
#### Test writing with Blinky example
##### Get the source
found one example that works with SDK V1.2 (which is based on FreeRTOS, as of writing)
* https://github.com/mattcallow/esp8266-sdk/tree/master/rtos_apps/01blinky
##### Compile
Read `2A-ESP8266__IOT_SDK_User_Manual_EN` document in
[this](http://bbs.espressif.com/viewtopic.php?f=51&t=1024) link.
It's configured 2048KB flash
```
BOOT=new APP=1 SPI_SPEED=80 SPI_MODE=QIO SPI_SIZE_MAP=5 make
BOOT=new APP=2 SPI_SPEED=80 SPI_MODE=QIO SPI_SIZE_MAP=5 make
```
or old way... this works not sure this is ok.
```
make BOOT=new APP=0 SPI_SPEED=80 SPI_MODE=QIO SPI_SIZE_MAP=2
```
##### Flashing
* power off ESP8266 board
* connect GPIO0 to GND, connect GPIO2 to VCC
* power on
* write
```
sudo /opt/Espressif/esptool-py/esptool.py \
--port /dev/ttyUSB0 write_flash \
0x00000 $SDK_PATH/bin/"boot_v1.4(b1).bin" \
0x01000 $BIN_PATH/upgrade/user1.2048.new.5.bin \
0x101000 $BIN_PATH/upgrade/user2.2048.new.5.bin \
0x3FE000 $SDK_PATH/bin/blank.bin \
0x3FC000 $SDK_PATH/bin/esp_init_data_default.bin
```
_change `/dev/ttyUSB1` to whatever you have._
or the old way...this works not sure this is ok.
```
cd $BIN_PATH
sudo /opt/Espressif/esptool-py/esptool.py \
--port /dev/ttyUSB0 write_flash \
0x00000 eagle.flash.bin 0x40000 eagle.irom0text.bin
```
* power off
* disconnect GPIO0 so that it is floating
* connect GPIO2 with serial of 470 Ohm + LED and to GND
* power On
LED should blink on and off every second

### About
Files in this folder (embedding/esp8266) are copied from
examples/project_template of esp_iot_rtos_sdk and modified for JerryScript.
You can view online from [this](https://github.com/espressif/esp_iot_rtos_sdk/tree/master/examples/project_template) page.
### How to build JerryScript for ESP8266
#### 1. SDK
Follow [this](./docs/ESP-PREREQUISITES.md) page to setup build environment
#### 2. Patch ESP-SDK for JerryScript
Follow [this](./docs/ESP-PATCHFORJERRYSCRIPT.md) page to patch for JerryScript building.
Below is a summary after SDK patch is applied.
#### 3. Building JerryScript
```
cd ~/harmony/jerryscript
make -f ./targets/esp8266/Makefile.esp8266 clean
make -f ./targets/esp8266/Makefile.esp8266
```
Output files should be placed at $BIN_PATH
#### 4. Flashing for ESP8266 ESP-01 board (WiFi Module)
Steps are for ESP8266 ESP-01(WiFi) board. Others may vary.
Refer http://www.esp8266.com/wiki/doku.php?id=esp8266-module-family page.
##### 4.1 GPIO0 and GPIO2
Before flashing you need to follow the steps.
1. Power off ESP8266
2. Connect GPIO0 to GND and GPIO2 to VCC
3. Power on ESP8266
4. Flash
##### 4.2 Flashing
```
make -f ./targets/esp8266/Makefile.esp8266 flash
```
Default USB device is `/dev/ttyUSB0`. If you have different one, give with `USBDEVICE`, like;
```
USBDEVICE=/dev/ttyUSB1 make -f ./targets/esp8266/Makefile.esp8266 flash
```
### 5. Running
1. Power off
2. Disonnect(float) both GPIO0 and GPIO2
3. Power on
Sample program here works with LED and a SW with below connection.
* Connect GPIO2 to a LED > 4K resistor > GND
* Connect GPIO0 between VCC > 4K resistor and GND
If GPIO0 is High then LED is turned on longer. If L vice versa.
