#### 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
#### Tools
The rest of this document will assume that you download all necessary tools into
a common directory structure. For the sake of simplicity, `$HOME/Espressif` will
be used as the root of this structure. Feel free to deviate from this but then
adapt all the paths accordingly.
```
mkdir $HOME/Espressif
```
##### Toolchain
Download the [toolchain](https://github.com/espressif/ESP8266_RTOS_SDK/tree/v3.0.1#get-toolchain)
pre-built for your development platform to `$HOME/Espressif` and untar it. E.g.,
on Linux/x86-64:
```
cd $HOME/Espressif
tar xvfz xtensa-lx106-elf-linux64-1.22.0-88-gde0bdc1-4.8.5.tar.gz
```
##### Espressif SDK: use Espressif official
```
cd $HOME/Esprissif
git clone https://github.com/espressif/ESP8266_RTOS_SDK.git -b v2.1.0
```
This version is tested and works properly.
##### ESP image tool
```
cd $HOME/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 $HOME/Espressif
git clone https://github.com/themadinventor/esptool
```
##### Set environment variables
Set environment variables, might also go in your `.profile`:
```
export PATH=$HOME/Espressif/xtensa-lx106-elf/bin:$PATH
export SDK_PATH=$HOME/Espressif/ESP8266_RTOS_SDK
export ESPTOOL_PATH=$HOME/Espressif/esptool
export BIN_PATH=(to output folder path)
```
#### 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 $HOME/Espressif/esptool/esptool.py \
--port /dev/ttyUSB0 write_flash \
0x00000 $SDK_PATH/bin/"boot_v1.7.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 $HOME/Espressif/esptool/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

### How to build JerryScript for ESP8266
#### 1. SDK
Follow [this](./docs/ESP-PREREQUISITES.md) page to setup build environment
#### 2. Building JerryScript
```
# assume you are in jerryscript folder
make -f ./targets/baremetal-sdk/esp8266-rtos-sdk/Makefile.esp8266
```
Output files should be placed at $BIN_PATH
#### 3. Flashing for ESP8266 12E
Follow
[this](http://www.kloppenborg.net/images/blog/esp8266/esp8266-esp12e-specs.pdf) page to get details about this board.
```
make -f ./targets/baremetal-sdk/esp8266-rtos-sdk/Makefile.esp8266 flash
```
Default USB device is `/dev/ttyUSB0`. If you have different one, give with `USBDEVICE`, like;
```
USBDEVICE=/dev/ttyUSB1 make -f ./targets/baremetal-sdk/esp8266-rtos-sdk/Makefile.esp8266 flash
```
### 4. Running
* power off
* connect GPIO2 with serial of 470 Ohm + LED and to GND
* power On
LED should blink on and off every second
#### 5. Cleaning
To clean the build result:
```
make -f ./targets/baremetal-sdk/esp8266-rtos-sdk/Makefile.esp8266 clean
```
To clean the board's flash memory:
```
make -f ./targets/baremetal-sdk/esp8266-rtos-sdk/Makefile.esp8266 erase_flash
```
### 6. Optimizing initial RAM usage (ESP8266 specific)
The existing open source gcc compiler with Xtensa support stores const(ants) in
the same limited RAM where our code needs to run.
It is possible to force the compiler to store a constant into ROM and also read it from there thus saving RAM.
The only requirement is to add `JERRY_ATTR_CONST_DATA` attribute to your constant.
For example:
```C
static const lit_magic_size_t lit_magic_string_sizes[] =
```
can be modified to
```C
static const lit_magic_size_t lit_magic_string_sizes[] JERRY_ATTR_CONST_DATA =
```
That is already done to some constants in jerry-core. E.g.:
- vm_decode_table
- ecma_property_hashmap_steps
- lit_magic_string_sizes
- unicode_letter_interv_sps
- unicode_letter_interv_len
- unicode_non_letter_ident_
- unicode_letter_chars
