==== Required software ====
 
To make it work you need:
 
* flashrom from svn
 
* [https://gitorious.org/gnutoo-personal-arduino-projects/serprog-duino serprog-duino which runs on the arduino]
 
* The avr toolchain(avr-gcc, avr-libc,make etc...)
 
==== Building the software ====
 
$ svn co svn://flashrom.org/flashrom/trunk flashrom
 
$ cd flashrom && make
 
$ cd ../
 
$ git clone git://gitorious.org/gnutoo-personal-arduino-projects/serprog-duino.git
 
$ cd serprog-duino && make && make upload
 
 
 
==== Running flashrom ====
 
./flashrom -p serprog:dev=/dev/ttyACM0:2000000
 
 
 
=== Advantages and disadvantages ===
 
* <s>The speed isn't that great(about 3 minutes for reading+writing+verifying a 1M chip)</s>
 
* The speed is now much better thanks to a patch by Sebastian Parborg.
 
* it is made of very commonly available parts(if you can find an arduino uno, you will be able to build it).
 
* Voltage issues( SPI levels are at 5v, it's problematic for flashing 3.3v chips...)
 
 
 
=== TODO ===
 
* Find a way to lower the voltage to 3.3v
 
* Fix the arduino UNO speed and reliability issues

This page collects information about the serprog protocol and the programmers implementing it.

Protocol

See serprog-protocol.txt in the source tree. It is designed to be compact and allow efficient storage in limited memory of programmer devices.

Hardware

AVR flasher by Urja Rannikko

Prototype RS232 AVR parallel flash programmer

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.

AVR flasher by eightdot

FIXME: Link?

Arduino Mega flasher by fritz

[1] [2] [3] FIXME: More info?

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 and in this coreboot mailing list thread.

atmegaXXu2-flasher by Stefan Tauner

Like the InSystemFlasher this one uses LUFA on an AVR microcontroller to tunnel the serial data over USB.

Arduino flasher by GNUtoo

For detailed instructions on how to use different Arduino models to access SPI flash chips see Serprog/Arduino flasher.

Arduino Uno connected using a breadboard

Frser-duino

The source can be found here

Teensy 3.1 SPI + LPC/FWH Flasher

serprog-stm32vcp by Chi Zhang

The most powerful serprog-based programmer is built upon an ARM Cortex-M3 (STM32F103) featuring up to 36 MHz SPI clock. See his github page for further details, source code etc.
