# 
> DIY - Build It Yourself
If you are considering / curious about the build process of the Retro ESP Launcher, you will need a few things to prepare
## Preperation
> Git going
Clone the **Master** [Official Retro ESP32](https://github.com/retro-esp32/RetroESP32/) repo
```shell
git clone -b master --single-branch [email protected]:retro-esp32/RetroESP32.git --recursive
cd RetroESP32
git submodule update --init --recursive
git submodule foreach git pull origin master
chmod -R 777 Scripts
cd Scripts
./installer
```
It will take a while since we run a few ```git submodule``` inside the repository
## Toolchain
> You will need the xtensa esp32 toolchain
***Note:*** You only need to install the xtensa toolchain. The esp-idf is included in this repository.
- [Linux](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/linux-setup.html)
- [Mac OS](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/macos-setup.html)
- [Windows](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/windows-setup-scratch.html)
## Bash Scripts
> Some tools to help you along your way
Navigate to you newly cloned repository and execute the following
```
chmod -R 777 Scripts
cd Scripts
```
***Note:*** All bash scripts **MUST** be executed from the Scripts folder.
### Submodule Branches
> Make sure all the submodules are on the right branches
```
./branches
```
### Replace files for ILI9342 drivers
> Copy relevant files for ILI9342 TFT LCD
```
./replace
```
### ESP32 Environment Installer
> Install all thing necessary (NIX/OS X) *Windows Coming Soon*
```
./installer
```
### Environmanet Variables
> Set all your paths
> Be sure to run installer first
```
source ./helpers/paths
```
### Build Firmware
> Follow Onscreen Prompts
> if this is your first time running the executable, answer **Y** to the options
```
./firmware
```
You will now have a file called **Retro ESP32.fw** in the Firmware/Release folder.
You can copy this onto your *SD Card* into the ***odroid/firmware*** folder
##### Enabling new firmware
> Insert the sd card into your Retro ESP32 / (Odroid Go) and follow the prompts
| Boot| Settings| List| Select| Write| Reboot|
| ----- | ----- | ----- | ----- | ----- | ----- |
|  |  |  |  |  |  |
### Build and Load OTA
> Follow Onscreen Prompts
> if this is your first time running the executable, answer **Y** to the applicable options
### OTA
> Flash directly to ESP32
This is the easiest option, simple follow the onscreen prompts!
```
./ota
```
*note:*
You will need to set the SPI ram for the emulators
| Screen Grab | Instructions |
| ----------------------------------------- | ------------------------------------------------------------ |
|  | Answer **Y** |
|  | Answer **N** |
|  | Answer **Y** (This is IMPORTANT) |
|  | Navigate to ```Component config -->``` |
|  | Navigate to ```ESP32-specific -->``` |
|  | Navigate to ```SPI RAM config -->``` |
|  | Navigate to ```Type of SPI RAM chip in use (some value) -->``` |
|  | Select ```Auto-detect``` |
### Erase
> Erase flash and storage from ESP32
```
./erase
```
### Arduino
> Create Firmware from Arduino ```.ino.bin``` file
```
./arduino
```
You will now have a ```.fw``` file in Arduino/firmware folder.
You can copy this onto your *SD Card* into the ***odroid/firmware*** folder
### 
# Retro ESP32
> Software Branch
Finally a new launcher for your Odroid-Go
```
cd Launchers/retro-esp32
make menuconfig
```
1. Select ```Restro ESP32 Configuration``` 
2. Select your options
* *Select* **LCD Driver Chip**
* *Select* **MENU Key Options**
