mTower is Trusted Execution Environment specially designed to be used on MicroController Units (MCUs) supporting ARM TrustZone technology (e.g., Cortex-M23/33/35p). mTower operates well under restrictions typical for such environment – small RAM and ROM sizes, relatively low performance, absence of rich OSes providing variety of services available on PCs or in enterprise environments. mTower is intended for usage in IoT, embedded devices, Smart Home applications, distributed heterogeneous networks and other environments where secure processing of sensitive data is necessary.

## 1. Introduction
The `mTower` is a new Trusted Execution Environment (TEE) specially designed
to protect size-constrained IoT devices based on Cortex-m23 MCU. Usage mTower
pre-embedded into the microcontroller, a module developer can use a simple SDK
that based on Global Platform API standards to add security to their solution.
---
## 2. License
mTower software consists of multiple components that are individually available
under different licensing terms. Terms for each individual file are listed at
the beginnings of corresponding files; also, all licenses are listed in
[COPYING] file.

## 3. Platforms supported
| Cortex-M23 | Cortex-M23 | Cortex-M33 (Qemu) | RISC-V |
|-----------------------|---------------------------|-------------|-----------|
| **NuMaker-PFM-M2351** | **M2351-Badge** | **V2M-MPS2** | **SparkFun RedBoard** |
|[](docs/numaker_pfm_m2351.md)|[](docs/m2351_badge.md) |[](docs/v2m-mps2-qemu.md)|[](docs/sparkfun_redboard.md)|
| **How to add a platform** ||||
|[](docs/port-new-platform.md)||||
Several platforms are supported. In order to manage slight differences
between platforms, a `PLATFORM` flag has been introduced.
| Platform | Composite PLATFORM flag | Maintained |
|---------------------------|------------------------------------|------------|
| [NuMaker-PFM-M2351] |`PLATFORM=numaker_pfm_m2351` | v0.5.0 |
| [M2351-Badge] |`PLATFORM=m2351_badge` | v0.5.0 |
| [V2M-MPS2] |`PLATFORM=mps2_an505_qemu` | v0.5.0 |
| [SparkFun RED-V RedBoard] |`PLATFORM=sparkfun_redboard` | v0.5.0 |
For information on adding a new platform see the [how to add a platform].

## 4. Get and build mTower software
Please see [build] for instructions how to run mTower on various devices.
---
## 5. Source code structure
The general [source code structure] for mTower is similar to the structure of the
multy platforms source code.
---
## 6. Coding standards
In this project we are trying to adhere to the mTower coding convention
(see [CodingStyle]). However there are a few exceptions that we had to make since
the code also uses other open source components.
---
## 7. Documentation
There is a brief overall [functionality description](docs/mtower_functionality_description.md) of mTower. Other mTower documentation for the project is located in the [docs] folder. The latest version of the specification that describes the mTower source code can be generated using [doxygen] tool from command line. To generate documentation, use
```sh
make docs_gen
```
command, and to view generated docs use
```sh
make docs_show
```
> Note that documentation on mTower is work in progress, and right now doxygen does not provide much documentation.

## 8. Contributing
If you want to contribute to the mTower project and make it better, your help is
very welcome. Contributing is also a great way to learn more about social
coding on Github, new technologies and and their ecosystems. [How to contribute
you can find here](.github/CONTRIBUTING.md).
