```
For the meaning of the board names have a look at [Hardware](doc/Hardware.md). For details refer to the code in [platformio.ini](platformio.ini) and look for the hardware definitions in [GwHardware.h](lib/hardware/GwHardware.h).
__linux users__<br>
You can typically install the esptool (once you have python 3 installed) with
```
sudo pip install esptool
```
__windows users__<br>
You can find a prebuild executable in tools: [esptool.exe](tools/esptool.exe).
Just create an empty directory on your machine, download the esptool to this directory and also download the binary (xxx-all.bin) from [releases](releases).
Afterwards you need to install the driver for the serial port to connect your ESP32 board. For a modern windows the driver at [FTDI](https://ftdichip.com/drivers/d2xx-drivers/) should be working.
After installing the driver check with your device manager for the com port that is assigned to your connected esp device.
Open a command prompt and change into the directory you downloaded the esptool.exe and the firmware binary.
Flash with the command
```
esptool.exe --port COM3 0x1000 xxxxx-xxxx-all.bin
```
Replace COM3 with the port shown in the device manager and the xxx with the name of the downloaded binary.
Update
******
To update a device you can use the Web-UI (Update tab). In principle you could also update a device using the initial flash command (and an xxx-all.bin) firmware but this would erase all your configuration.
So for normal operation just download a xxx-update.bin from the [release](release) page and use the UI to install it.
![install](doc/ota-ok1.png).
When you choose a file for the update the UI will check if it is a valid firmware file en will reject invalid ones.
When you choose a file for the update the UI will check if it is a valid firmware file and will reject invalid ones.
To really execute the update click the "Upload" button. You will have a progress indicator and get a notification about the update result.
Please reload the page in your browser after the "connected" state is green as the new version could have changes thatv otherwise will not work.
