Before building, the correct `ps7_init.[c;h]` and some other configuration files need to be copied into the misc folder of the FSBL. The FSBL will run without this step, but some interfaces might not work as expected.
These files are specific to the actual hardware used and located in the `bsp_z7/ps7_init` folder. The following examples assumes the zedboard.

##### Clone the submodules (FreeRTOS and lwIP):
```sh
git submodule init
git submodule update
git submodule update --init --recursive
```
##### To build the obsw, run the following command
Once:
Configure and generate using cmake:
```sh
mkdir -p build
cd build
mkdir build_z7
cd build_z7
cmake -DCMAKE_TOOLCHAIN_FILE=../bsp_z7/cmake/arm-none-eabi.toolchain ..
```
After adding a new .c file:
Compile (`-j` count your discretion):
```sh
cmake -DCMAKE_TOOLCHAIN_FILE=../bsp_z7/cmake/arm-none-eabi.toolchain ..
make -j 8
```
Every time
```sh
make -j 8"
```
The romeo-obsw binary can now be found in the `build` directory. The next step to deploy it is here: [DEBUG_ON_ZEDBOARD.md](./DEBUG_ON_ZEDBOARD.md).

Once:
Configure and generate using cmake:
```sh
mkdir -p build
cd build
mkdir build_linux
cd build_linux

### run
Run the binary
Run the binary:
```sh

The linux binary is supposed to be run against a simulator listening on UDP Ports. Command line options configure this connection (`./romeo-obsw --help`). A lightweight test simulator is at https://egit.irs.uni-stuttgart.de/ROMEO/obsw_dev_sim.
