|
|
OpenBLT is an open source bootloader for STM32, XMC, HCS12 and other
|
|
|
|
|
microcontroller targets.
|
|
|
|
|
|
|
|
|
|
OpenBLT enables you and your customers to update the firmware on your
|
|
|
|
|
microcontroller based product. A major benefit of OpenBLT being open source
|
|
|
|
|
is that you can customize and tweak the bootloader to your specific needs.
|
|
|
|
|
|
|
|
|
|
OpenBLT can be ported to any 8-bit, 16-bit, or 32-bit microcontroller and
|
|
|
|
|
currently runs on microcontrollers with an ARM Cortex-M, Infineon Tricore, and
|
2018-07-20 01:15:01 -07:00
|
|
|
Freescale HCS12 core. It is most popular on STM32 microcontrollers.
|

|
|
|
|
|
|
|
|
By default, it supports communication interfaces such as: RS232, CAN, USB,
|
2018-07-20 01:15:01 -07:00
|
|
|
TCP/IP and it ships with the easy-to-use [MicroBoot](https://www.feaser.com/openblt/doku.php?id=manual:microboot)
|
|
|
|
|
PC tool for initiating and monitoring the firmware update. Performing firmware
|
|
|
|
|
updates directly from an SD-card is also supported.

|
|
|
For those that prefer a command line program for performing firmware updates,
|
|
|
|
|
there is [BootCommander](https://www.feaser.com/openblt/doku.php?id=manual:bootcommander).
|
|
|
|
|
If you would rather build your own firmware update tool for seamless integration
|
|
|
|
|
into your existing toolset, then have a look at the OpenBLT host library
|
|
|
|
|
([LibOpenBLT](https://www.feaser.com/openblt/doku.php?id=manual:libopenblt)). This
|
|
|
|
|
is an easy-to-use shared library, enabling you to develop your own firmware update
|
|
|
|
|
tool quickly, in the programming language of your liking.

|
|
|
|
|
contains numerous preconfigured demo programs for popular and low-cost development
|
|
|
|
|
boards, making it possible for you to get started with the bootloader quickly.
