Serprog (overview)
|
|
==================
|
|
|
|
This page collects information about the serprog protocol and the programmers implementing it.
|
|
|
|
Protocol
|
|
========
|
|
|
|
See :doc:`/supported_hw/supported_prog/serprog/serprog-protocol`. It is designed to be compact and allow efficient storage in limited memory of programmer devices.

AVR flasher by Urja Rannikko
|
|
============================
|
|
|
|
.. image:: 300px-Avr_rs232_programmer.jpg
|
|
|
|
The Prototype RS232 AVR parallel flash programmer of Urja Rannikko was the first implementation of the serprog protocol.
|
|
|
|
The source code can be found `here <https://github.com/urjaman/frser-atmega88>`_.

|
InSystemFlasher by Juhana Helovuo
|
|
=================================
|
|
|
|
This was the first one that talks to SPI devices via serial over USB.
|
|
Details can be found in the `coreboot wiki <https://www.coreboot.org/InSystemFlasher>`_ and in this
|
|
`coreboot mailing list thread <https://mail.coreboot.org/pipermail/coreboot/2011-February/063349.html>`_.

atmegaXXu2-flasher by Stefan Tauner
|
|
===================================
|
|
|
|
Like the InSystemFlasher this one uses LUFA on an AVR microcontroller to tunnel the serial data over USB.

Various Arduino based flashers
|
|
==============================
|
|
|
|
Frser-duino
|
|
-----------
|
|
|
|
This project contains `source code <https://github.com/urjaman/frser-duino/>`_ to install on Arduino devices.
|
|
|
|
This developer also have various ports on `github repo <https://github.com/urjaman?tab=repositories>`_ for several microcontroller boards, such as:
|
|
|
|
* `frser-teensyflash <https://github.com/urjaman/frser-teensyflash>`_: A port for the teensy microcontroller board
|
|
|
|
There also various other interesting projects such as:
|
|
|
|
* `fast-usbserial <https://github.com/urjaman/fast-usbserial>`_: A software to make arduino with 8u2 or 16u2 flashing faster and more reliable]
|
|
* :ref:`arduino shield`

Using a 5v Arduino at 3.3V
|
|
--------------------------
|
|
|
|
Information on it can be found in this doc: :doc:`/supported_hw/supported_prog/serprog/arduino_flasher_3.3v`

|
5V arduino with level shifter
|
|
-----------------------------

Teensy 3.1 SPI + LPC/FWH Flasher
|
|
--------------------------------
|
|
|
|
A Teensy 3.1 based small flasher by Urja Rannikko documented here: :doc:`/supported_hw/supported_prog/serprog/teensy_3_1`

HydraBus multi-tool
|
|
-------------------
|
|
|
|
HydraBus (hardware) with HydraFW (firmware) is an open source multi-tool for learning, developing, debugging, hacking and penetration testing
|
|
of embedded hardware. It is built upon an ARM Cortex-M4 (STM32F405). The source code for HydraFW is available
|
|
`on GitHub <https://github.com/hydrabus/hydrafw>`_. Refer to `their GitHub Wiki <https://github.com/hydrabus/hydrafw/wiki/HydraFW-SPI-guide#flashrom-usage>`_
|
|
for more details on how to use HydraBus with flashrom.

stm32-vserprog by Chi Zhang
|
|
-----------------------------
|
|
|
|
A powerful option is `stm32-vserprog <https://github.com/dword1511/stm32-vserprog#stm32-vserprog>`_, a firmware for various STM32-based boards
|
|
that turns them into serprog-based programmers with SPI clock speeds up to 36 MHz.
