+# Firmware Installation (Freenove ESP32S3 N16R8)
+
+## Manual Firmware Installation / Update
+
+  ### 1. Flash microcontroller content (ESP32S3 based microcontroller)
+
+   - Put your board into bootloader mode (IO0 grounded + board reset)
+   - Use port labeld with `USB-OTG`
+   - Three files to be flashed with correct flash offset
+
+      | Filename          | Offset      | Description
+      |:------------------|:------------|:------
+      | bootloader.bin    | 0x0         | Bootloader
+      | partitions.bin    | 0x8000      | Partition table
+      | firmware.bin      | 0x10000     | User application
+  
+  - Use `Flash Download Tool` from Espressif or the console-based `esptool` to flash the files.
+  Usage is described [here](https://jomjol.github.io/AI-on-the-edge-device-docs/Installation/#flashing-using-the-flash-tool-from-espressif-gui).
+
+
+  ### 2. Prepare SD Card
+  - Format SD card with FAT32 (Windows recommenend. In MacOS formated cards could not working properly)
+  - Copy folders `/config` and `/html` from zip file to SD card root folder
+
+
+  ### 3. Configure WLAN
+
+  #### Modify content directly in config file
+    Use config.json template from `sdcard/config/template` folder, copy it to 
+    `sdcard/config` folder and to configure your wlan connection.<br>
+    Note 1: If device is already booted once, a full config with default configuration is already sitting in `/config` folder. 
+    You can also use this file, search for section network and adapt the wlan config there.
+    Note 2: Be careful with syntax. Messing up the JSON notation, config is getting rejected.
+
+
+## Alternative Provisioning Options
+
+### Device Provisioning via Web Installer
+
+ Usage is decribed [here](https://github.com/Slider0007/AI-on-the-edge-device/blob/develop/docs/Installation/DeviceProvisioning/WebInstaller.md).
+
+
+### Device Provisioning via Access Point
+
+ Usage is decribed [here](https://github.com/Slider0007/AI-on-the-edge-device/blob/develop/docs/Installation/DeviceProvisioning/AccessPoint.md).
+
+
+### Firmware Update via OTA (Over-The-Air)
+
+  Note: This option is only available after initial installation was successful and regular device web interface is accessible.
+
+  Select firmware package zip from github repository in WebUI OTA Updater page. 
+  The device is getting updated automatically. The existing configuration will not be overwritten.
+
