## How to prepare build env and tools ## How to prepare build env and tools
Use tools from the Buddy FW and a separate Atmel AVR GCC 5.4. As the first step extract the AVR-GCC to some dir, e.g. `/home/user/AVRToolchainMMU/avr8-gnu-toolchain-5.4.0`
Extract the AVR-GCC to some dir, e.g. `/home/user/AVRToolchainMMU/avr8-gnu-toolchain-5.4.0` Add `/home/user/AVRToolchainMMU/avr8-gnu-toolchain-5.4.0/bin` to your `PATH`.
``` ```
mkdir .dependencies mkdir .dependencies
cd .dependencies cd .dependencies
ln -s ../../STM32Toolchain/clang-format-9.0.0-noext mkdir gcc-avr-5.4.0
ln -s ../../STM32Toolchain/cmake-3.15.5 cd ..
ln -s ../../STM32Toolchain/ninja-1.9.0 utils/bootstrap.py
ln -s ../../AVRToolchainMMU/avr8-gnu-toolchain-5.4.0
``` ```
## How to build the preliminary project so far: `bootstrap.py` will now download all the "missing" dependencies into the `.dependencies` folder:
Please make sure you have your `cmake`, `clang-format` and `ninja` in path - clang-format-9.0.0-noext
- cmake-3.15.5
- ninja-1.9.0
Note: bootstrap.py will not try to download the AVR-GCC as there is already a directory called
`gcc-avr-5.4.0`. This will be fixed when we find out where to download the correct packages reliably.
## How to build the preliminary project so far:
Now the process is the same as in the Buddy Firmware:
```
utils/build.py
```
builds the firmware.hex in build/mmu_release
In case you'd like to build the project directly via cmake you can use an approach like this:
``` ```
mkdir build mkdir build
cd build cd build
cmake .. -G Ninja -DCMAKE_TOOLCHAIN_FILE=../../cmake/AnyAvrGcc.cmake cmake .. -G Ninja -DCMAKE_TOOLCHAIN_FILE=../cmake/AnyAvrGcc.cmake
ninja ninja
``` ```
Should produce a firmware.hex file Should produce a firmware.hex file as well.
