## Prerequisits for build with Docker
##### Info
IRS wireguard VPN can cause network issues with docker. 

##### Install Docker
If you are using macOS or Windows, please use this tutorial:
- https://www.docker.com/get-started/

On Linux simply use your package manager to install ```docker``` and prepare everything using these commands, to avoid permission denied errors:

```sh 
sudo systemctl start docker
sudo groupadd docker
sudo usermod -aG docker $USER   
sudo reboot
```


## FSBL

FSBL is the First Stage Boot Loader and prepares the CPU and FPGA configuration for booting up the Second Stage Bootloader and finally the flight software. 

##### Clone the repository and build the docker image:

```sh
cd docker/compile_fsbl/
git clone https://github.com/Xilinx/embeddedsw/
docker build -t compile_fsbl .
```

##### To build the FSBL, run the following command in the `docker/compile-fsbl` directory:
```sh
docker run -v ./embeddedsw:/fsbl compile_fsbl /bin/bash -c "cd lib/sw_apps/zynq_fsbl/src && make BOARD=zed SHELL=/bin/bash"
```


If you want, copy the fsbl.elf to the docker/compile_fsbl directory for easier access:
```sh
cp embeddedsw/lib/sw_apps/zynq_fsbl/src/fsbl.elf .
```

## Steps
1. Configure doxygen:

## mission_rust

##### Build the docker image:
```sh
export DOT_PATH=/usr/local/bin
```


## obsw

##### Clone the submodules (FreeRTOS and lwIP):
```sh
git submodule init
git submodule update
```

##### Build the docker image:
```sh
cd docker/compile_obsw/
docker build -t compile_obsw .
```

##### To build the obsw, run the following command in the `docker/compile_obsw` directory:
```sh
docker run -v $(pwd)/../..:/obsw compile_obsw /bin/bash -c "mkdir -p build_cli && cd build_cli && cmake -DCMAKE_TOOLCHAIN_FILE=../bsp_z7/cmake/arm-none-eabi.toolchain .. && make -j 8"
```

The romeo-obsw binary can now be found in the `build_cli` directory.
