General information
-------------------
From <http://www.embedded-projects.net/index.php?page_id=165>:
1. What is USBprog?
USBprog is a free programming adapter. You can easily install different
firmware versions from an “online pool” over USB. The adapter can be used
for programming and debugging AVR and ARM processors, as USB-to-RS232
converter, as JTAG interface or as simple I/O interface (5 lines).
2. Who needs USBprog?
Hardware and software developers who work with Windows, Linux and other
operating systems.
3. What is so special about the concept of USBprog?
Given time, there will be a growing pool of firmware versions. If you have
to work with a new module you will ideally find the matching firmware to
program or connect to this new module in the online pool.
If there is no matching firmware for the required module you shouldn't
hastily buy a far too expensive adapter, but ask if it paid to write a new
firmware for USBprog and thus to invest in the firmware pool. Often it is
done quite quickly, because you can enhance existing software tools. Like in
the case of the AVR ISP 2 clone that can be used with every application that
supports the original adapter of Atmel, or the adapter for the OpenOCD, a
product developed within 2 to 3 days.
This tool
---------
1. Overview
This is the programming tool needed to replace the firmware on the USBprog
hardware. It automatically retrieves a list of available firmwares from the
internet, downloads them and uploads it to the USBprog adapter.
2. Operating systems
The tool runs on Linux (primary platform) and Microsoft Windows (secondary
platform). It should be very easy to port to other Unix-like operating
systems that have libusb -- including Apple MacOS X.
3. Requirements
a) libusb <http://libusb.sourceforge.net> and
<http://libusb-win32.sourceforge.net>
b) libxml2 <http://xmlsoft.org>
c) libcurl <http://curl.haxx.se>
4. Interfaces
The tool consists of a library (written in C++) that manages devices and the
firmware pool (i.e. the cache on disk) and a command line interface. That
interface is designed to be used interactively through a shell and in batch mode
(similar to avrdude).
A graphical interface is coming. The “old” GUI which doesn't use this
library is available at <http://www.ixbat.de/index.php?page_id=165>.
5. Installation
Installation on Linux (or Unix-like operating systems) should be very straight
forward because it uses autoconf/automake/libtool (i.e. the familiar
./configure mechanism).
For Win32, use the provided binary. If you want to compile yourself, install
MinGW. Devcpp project files are included. For more information about installing
libusb on Windows, see the web page.
6. Usage
To learn how to use the program, just read its manual page, usbprog(1).
For Win32 users, a HTML version is included.
7. Author, Copyright, Bugs
This tool was written by Bernhard Walle <bernhard@bwalle.de>. Parts of
the source code have been taken from the old tool which was written by
Benedikt Sauter <sauter@ixbat.de>.
