+description: Tutorial for building the STM32 microcontroller firmware.
+---
+
+The firmware can be build on any host PC (but yet only tested on Linux machine).
+
+### Step 1: Clone 'fw-openmower-v2' firmware repository
+
+It's important to clone the 'fw-openmower-v2' repository including it's submodules:
+```bash
+sudo apt install git docker
+git clone --recurse-submodules https://github.com/xtech/fw-openmower-v2.git
+```
+
+### Step 2: Compile Firmware
+
+```bash
+cd fw-openmower-v2
+./build-binary.sh
+```
+
+### Step 3: Copy Compiled Firmware to Mower
+
+Copy the compiled firmware binary (.elf format) to your (V2) mower:
+```bash
+scp out/openmower.elf openmower@openmower.local:"
+```
+The firmware should be copied to your mower where it could be uploaded to the STM32 microcontroller,
+see [Flashing STM32 From CM4]({{< ref "flashing-stm32-from-cm4" >}} "Flashing STM32 From CM4").
