Project description

# mbed-flasher

## Description

mbed-flasher is a simple Python-based tool for flashing single or multiple boards.
It provides a simple Command Line Interface and Python API for flashing.

The purpose is to provide a clean and simple library that is easy to integrate to other tools.
It can be easily developed further to support flashing in mbed OS and other platforms.
Developers can also use it as a standalone tool for flashing their development boards.


## Installation

To install the flasher, use:

`python setup.py install`

To install the flasher in development mode:

`python setup.py develop`

To use JLink flashing, additional package needs to be installed from [here](https://www.segger.com/downloads/jlink/#J-LinkSoftwareAndDocumentationPack).
JLinkExe must be found from PATH for flasher to be able to use it.

## Usage

This tool has been tested and verified to work with Windows 7 and Ubuntu (14.04 LTS) Linux.

Devices used in verification: NXP K64F, Nucleo F401RE, BBC micro:bit.

See the actual usage documentation [here](doc/usage.md).

## Running unit tests

Required pre-installed packages: coverage, mock

```
sudo pip install coverage mock
```

Execute all tests:
```
coverage run -m unittest discover -s test
```
Execute hardware tests:
```
coverage run -m unittest discover -s test.hardware
```
Execute non-hardware tests:
```
coverage run -m unittest discover -s test.non_hardware
```



Generate a coverage report:

```
coverage html
```

## Creating the installer

**For Windows:**
```
python setup.py build
python setup.py bdist_msi
```

**For Linux:**
```
python setup.py build
//for rpm package
python setup.py bdist_rpm
```
