This file will help you to setup all required software on your system, compile

the source code, and use the tools and flash the bootloader software to the

AMiRo base modules.

    1.3  GNU Make

================================================================================

1 - REQUIRED SOFTWARE

---------------------

The only third party software required are stm32flash and GCC for ARM embedded

devices. While the latter is a compiler to build binaries that are compatible

with the microcontrollers (MCUs) of AMiRo, the former is used to write this data

to the hardware.

1.1 - stm32flash

----------------

To build the tool from source, clone the GIT repository to a local folder on

your machine:

  >$ git clone git://git.code.sf.net/p/stm32flash/code

Make sure that you have selected version 0.4 or later of the tool. You can now

build the tool simply by executing 'make'. Finally, you must make the resulting

binary (stm32flash) globally available in your environment. You can do so by

either copying the file to an appropriate location (e.g. /usr/local/bin/) or

creating an according link. The tool must be available as 'stm32flash' in every

new shell.

1.2 - GCC ARM Embedded Toolchain

--------------------------------

Various versions of the GCC for ARM embedded devices can be found at

<https://launchpad.net/gcc-arm-embedded>. For installation of the compiler

toolchain, please follow the instructions that can be found on the web page.

If you have access to the AMiRo-OS project as well, it is highly recommended

to use the setup application provided there.

1.3 - GNU Make

--------------

GNU Make usually comes as preinstalled tool on Ubuntu based operating systems.

If your system is missing GNU Make, it is recommended to install it from the

standard repositories since no special requirements (e.g. features of a very

recent version) are required.

1.4 - CMake

-----------

In order to build the SerialBoot host application, CMake version 2.8 or later is

required. If possible, it is recommended to instal it from the standard

repositories of your operating system.

2 - RECOMMENDED SOFTWARE

------------------------

AMiRo-BLT provides support for the QtCreator IDE. In order to setup according

projects, use the ./setup.sh script and follow the instructions. It will

automatically generate the required files and you can import the projects by

opening the .creator files with Qtcreator IDE.

3 - COMPILING THE SOURCE CODE

-----------------------------

The AMiRo-BLT project is separated into two major parts: target- and host-

related software. The former comprises the bootloaders for the three base

modules of the AMiRo. The latter is the SerialBoot tool, which can be used to

flash further binaries (e.g. a complex operating system) to the microcontrollers

without connecting to the module directly (data is passed through via CAN bus).

Since the programming connector of the lowermost AMiRo module is the only one

accessible when the robot is fully set up, this enables to update the firmware

even for other modules.

3.1 - target software

---------------------

In the ./Target/Demo/ directory there are three subfolders, one for each AMiRo

base module. Within each of these is an additional Boot/ folder

(./Target/Demo/<device>/Boot/), which contains a makefile. Each bootloader can

be compiled by executing 'make' in these directories.

In order to flash the bootloader to a microcontroller, you first have to set

full read and write permissions to the USB ports of your system. You can do so

by executing the following command:

  >$ sudo echo 'KERNEL=="ttyUSB[0-9]*",NAME="tts/USB%n",SYMLINK+="%k",MODE="0666"' > /etc/udev/rules.d/50-ttyusb.rules

Now connect the module you want to flash directly to your system (note that

indirect flashing is not possible for the bootloader itself) and run the command

  >$ make flash

If the procedure was not successful, the following hints might help:

  - Could the makefile execute the stm32flash tool?

  - Are the permissions for USB ports set correctly?

  - Are there any other applications using the serial connection?

  - Is the AMiRo module connected to your system?

  - Is the AMiRo module powered up?

ATTENTION:

Never flash a bootloader to the wrong module! Doing so might cause severe errors

and damage the robot.

3.2 - host software

-------------------

The SerialBoot tool can be built by using cmake. The according CMakeLists.txt

file can be found in the ./Host/Source/SerialBoot/ directory. To ensure

compatibility with other software (e.g. AMiRo-OS) it is higly recommended to use

the provided ./setup.sh script to build SerialBoot. In the end the binary path

should be ./Host/Sotware/SerialBoot/build/SerialBoot.
