## The Idea
|
|
|
|
|
|
|
|
|
|
Löwe OS is being developed to be a lightweight desktop operating system for
|
|
|
|
|
ARM-based computers, tablets, mobile phones etc. Here are some concepts behind
|
|
|
|
|
it:
|
|
|
|
|
|
|
|
|
|
1. The OS is free with open source codes, distributed under terms of [CC BY-ND 4.0](LICENSE.md).
|
|
|
|
|
2. The OS will have POSIX-compliant API.
|
|
|
|
|
3. The OS will include graphical system, shell and generic utilities as a part
|
|
|
|
|
of it, being designed to work as a solid product.
|
|
|
|
|
4. The OS will respect user's privacy and will not track his/her actions and data.
|
|
|
|
|
5. The OS will stive to be secure and robust.
|
|
|
|
|
|
|
|
|
|
## Hardware
|
|
|
|
|
|
|
|
|
|
Early development is going for **Raspberry PI3** board and its emulation using
|
|
|
|
|
**QEMU**.
|
|
|
|
|
|
|
|
|
|

|
* [Naming convention](docs/naming-convention.md)

|
## Compilation
|
|
|
|
|
|
|
|
|
|
To compile Löwe OS run `make` from repository root, make sure
|
|
|
|
|
[Clang](https://clang.llvm.org/) compiler is installed on your system.
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ make
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Output files will be stored inside newly created `build` folder.
|
|
|
|
|
|
|
|
|
|
## Run
|
|
|
|
|
|
|
|
|
|
To run Löwe OS on QEMU, execute `make run` command for the repository root.
|
|
|
|
|
|
|
|
|
|
To run Löwe OS on Raspberry PI3, follow these steps:
|
|
|
|
|
|
|
|
|
|
1. Compile project and copy `build/kernel8.img` and `config.txt` files to
|
|
|
|
|
Micro SD card
|
|
|
|
|
2. Make sure latest boot code is installed on the SD card
|
|
|
|
|
3. Insert SD card into your Raspberry PI3 and power it up
|
|
|
|
|
|
|
|
|
|
## Debug
|
|
|
|
|
|
|
|
|
|
If you have `gdb-multiarch` and **QEMU** installed, then debugging should be as
|
|
|
|
|
easy as `make debug`.
|
|
|
|
|
|
|
|
|
|
