\defgroup Core Bootloader Core
\brief Target independent code.
\details The bootloader core contains the main functionality of the bootloader,
independent of the microcontroller/compiler and independent of your
specific application. There in generally no need for you to make changes
here, unless you are adding new functionality such as the support for a
new communication interface or a different communication protocol.
By default the XCP version 1.0 is used as the communication transport layer
for remote firmware updates, for example via UART or CAN. Its official name
is ASAM MCD-1 XCP V1.0.0 and it is a universal measurement and calibration
protocol that defines a bus-independent, master-slave communication protocol
to connect ECU's with calibration systems. More information can be found at
http://www.asam.net/.
For local firmware updates, for example from a locally attached SD-card,
the FATFS file system is used as a target independent interface to access
files. More information can be found at
http://elm-chan.org/fsw/ff/00index_e.html

\mainpage OpenBLT Firmware Documentation
\details
\section into Introduction
This documentation covers the OpenBLT (Open source BootLoader Tool) firmware. With
OpenBLT you can make software updates through an on-chip communication interface
(RS232, CAN, TCP/IP, USB etc.), without the need of specialized debugger hardware.
\section arch Software Architecture
The software program's architecture is divided into 4 major categories, namely the
application code (App), target independent code (Core), target dependent code
(Target), and compiler specific code (Comp).
\image html openblt_architecture.png
\image latex openblt_architecture.png
To configure and fine-tune the bootloader for integration in your product, all you have
to do is take the demo bootloader project for the microcontroller and compiler you are
using, and (optionally) modify just the application code (App) to fit your needs. This
typically involves changing the configuration header file (blt_conf.h) and the
implementation of the hook functions (hooks.c).
For more in-depth information behind the design of the OpenBLT bootloader, you can visit:
https://www.feaser.com/openblt/doku.php?id=manual:design.
