## Requirements:

### Known Issues
Ubuntu 22.04 has some version issues with the compile toolchain, consider using a newer version or other distribution or docker. Or solve the issue and add it here.

### Steps 
Install
1. `cmake`
2. `arm-none-eabi-gcc arm-none-eabi-gcc arm-none-eabi-binutils arm-none-eabi-gdb arm-none-eabi-newlib`
3. `doxygen` 
4. `graphviz`
5. `rustup`  || Install using your packet manager or alternatively use the rust install script:  `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh` (confirm default toolchain | nightly | complete | modify path variable: yes)



6. At last: Satisfy Rust requirements 

```sh
cd ../mission_rust
cargo update 
rustup toolchain install nightly
rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-gnu
rustup override set nightly
cargo build -Z build-std
```

## Build the 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. 

```sh
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

## mission_rust


## obsw

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

##### To build the obsw, run the following command

Once:
```sh
mkdir -p build
cd build
```

After adding a new .c file:
```sh
cmake -DCMAKE_TOOLCHAIN_FILE=../bsp_z7/cmake/arm-none-eabi.toolchain .. 
```

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).
