The goal of this project is to gather information about the Reciva 'Barracuda' radio module, in order to understand enough of the hardware to be able to provide alternative [[GPL]] firmware.


I'm an embedded firmware engineer, and I'm planning to spend some time on this project to see how hard it would be to get my own software up and running on the Barracuda hardware. If you think you can add anything to this project, feel free to use this wiki to share your information: add and edit!
The Sharpfin Project <i>needs the support</i> of keen and enthusiatic hobbyist/engineers - it is a mammoth task in understanding the internal workings of the radio - we have some partial schematics and are begining to analyse the [[GPL]] code, but there is lots to do, so

== Alternative firmware wishlist ==
 
The following list shows some features which would be possible to implement with the new firmware. This list is not complete, neither definitive, feel free to add your own ideas.
 
* No dependency on Reciva's database and servers
 
* Support for additional codecs (ogg, flac, etc) and protocols
 
* The Barracuda provides an USB 1.1 Host interface. Implement playing from USB storage device ?
 
* Accessibility features, eg talking menus for the blind
 
* ... More here ...
 
== Roadmap ==
 
This list describes the things that would be needed to create a platform on which an alternative firmware implementation could be provided, roughly in the right order.
 
* Creating an inventory of the components on the Barracuda board and their functions, and gathering technical information about these componentes where available.
 
* Find out what the testpads on the Barracuda PCB do - Identifying [[JTAG]] and [[UART]] would be really helpful here.
 
* Get a [[linux]] (console) shell to work on the current firmware to be able to get info about how the official software connects to the hardware. Memory maps, device drivers, stracing Reciva's applications ?
 
* Figure out which pieces are missing to drive the hardware - Does Reciva provide drivers to all hardware ? Is a bootloader provided ?
 
* Try to put as much pieces of the provided GPL code together to get a basic OS up and running. Find out how much Reciva added or modified of the original software packages.
 
* Get all the hardware components working: [[GPIO]], [[LCD display]], [[LEDs]], [[buttons]], [[usb]], [[network]], [[audio]]
 
== Questions ==
 
Some questions that come to mind when gathering the info
 
* There seems to be [[LIRC]] support in the kernel, reciva also provides lirc sources. How hard would it be to add a remote to existing radios ?
* What is the purpose of the libgpg-error package Recive provides ? Is this just used as a generic error reporting framework ?
* Does the Barracude use special co-processors or dedicated hardware for audio codecs ?

Sharpfin project

The goal of this project is to gather information about the Reciva 'Barracuda' radio module, in order to understand enough of the hardware to be able to provide alternative GPL firmware.

The Sharpfin Project needs the support of keen and enthusiatic hobbyist/engineers - it is a mammoth task in understanding the internal workings of the radio - we have some partial schematics and are begining to analyse the GPL code, but there is lots to do, so
