==== Required software ====
[[Teensy 3.1 SPI + LPC/FWH Flasher|A Teensy 3.1 based small flasher by Urja Rannikko.]]
To make it work you need:
* flashrom from svn
* [https://git.gitorious.org/gnutoo-personal-arduino-projects/serprog-duino.git serprog-duino which runs on the arduino]
* The avr toolchain(avr-gcc, avr-libc,make etc...)
==== Building the software ====
git clone git://gitorious.org/gnutoo-personal-arduino-projects/serprog-duino.git
svn co
==== Running flashrom ====
./flashrom -p serprog:dev=/dev/ttyACM0:57600


=== Advantages and disadvantages ===
* While the speed isn't that great(less than 10 minutes for reading+writing+verifying a 1M chip), there is huge room for improvements in the source code.
* it is made of very commonly available parts(if you can find an arduino uno, you will be able to build it).

Revision as of 09:22, 26 July 2015

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.

atmegaXXu2-flasher with Pomona SOIC hook attached

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

A Teensy 3.1 based small flasher by Urja Rannikko.


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.
