@ -76,13 +76,20 @@ 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 write_flash 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.
If you do not want to use the command line you first need to install python3 from the [download page](https://www.python.org/downloads/windows/) - use the Windows 64 Bit installer. Install using the default settings. Afterwards download [flashtool.pyz](../../raw/master/tools/flashtool.pyz) and run it with a double click.
If you do not want to use the command line there is a tool with an UI that allows you to flash the initial or update firmware.
Just download the exe for your windows system from the [ESP32N2K-Flasher Git Repository](https://github.com/wellenvogel/esp32n2k-flasher/releases/latest).
There is no installation needed - just start the downloaded exe.
Some Anti Virus Software may (accidently) tag this as infected. In this case you can still install the UI in two steps:
* you first need to install python3 from the [download page](https://www.python.org/downloads/windows/) - use the Windows 64 Bit installer. Install using the default settings.
* Afterwards download [flashtool.pyz](../../raw/master/tools/flashtool.pyz) and run it with a double click.
