+## 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 
+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`
+
+
+
+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).

+# Debugging on `zedboard`
+`zedboard` is the `Xilinx Zynq-7000` development board. 
+## Requirements [TBC]:
+- `OpenOCD`
+- `arm-none-eabi-gdb` 
+
+## Steps
+TODO: discuss this with paul
+1. Set Zedboard `boot mode` to JTAG and connect debugging PC to zedboard JTAG and UART USB port.
+TODO: what is which port, use distinct name/add a graphic
+2. On PC connected to zedboard JTAG USB port:
+```sh
+openocd -f board/digilent_zedboard.cfg
+```
+
+If you have one around, load bitstream at startup (go get a coffee, takes time with onboard JTAG, blue LED lights up when done):
+```sh
+openocd -f board/digilent_zedboard.cfg -c "init" -c "pld load 0 system.bit"
+```
+
+3. To use JTAG Boot for the OBSW, you first need to run the FSBL once.
+
+On build PC (adapt IP if different from debugging PC) in the folder where you build the FSBL as above:
+```sh
+arm-none-eabi-gdb fsbl.elf
+>target extended-remote localhost:3333
+>load
+>cont
+>^C^D^D
+```
+
+### (Optional) Automate this run:
+```sh
+arm-none-eabi-gdb fsbl.elf -iex "target extended-remote localhost:3333" -ex "set pagination off" -ex "load" -ex "break FsblHandoffJtagExit" -ex "cont" -ex="set confirm off" -ex "exit"
+```
+
+It will exit after the Zynq is configured and ready to firmware.
+
+Then load the actual OBSW, in the build (`build_cli` in the example above) folder run:
+```sh
+arm-none-eabi-gdb romeo-obsw
+>target extended-remote localhost:3333
+>load
+>cont
+```
+
+Again, `Command Line Interface (CLI) commands` can be moved to the GNU Debugger (DGB) call. Also, a small function is used as marker to return from GDB if the mission code returns (should not happen in production but might be useful during testing).
+```sh
+arm-none-eabi-gdb romeo-obsw -iex "target extended-remote localhost:3333" -ex "set pagination off" -ex "load" -ex "break done" -ex "cont" -ex="set confirm off" -ex "exit"
+```
+
+UART USB port should output something at `115200baud`, (I use moserial to monitor).
