Bootloader

The good bootloader, found on the Riscstation is the ABLE Bootloader, it is possible that this is the loader which is used on the radio module.

Bootloader Information Resources

• ARM Bootloaders

Operating system and device drivers

Linux 2.4.26 is running on the Samsung CPU. Sourcecode for drivers for the following devices is acknowledge to be available :

• USB Host device
• PCM audio output
• UART
• 'BAST' real time clock
• I2C interface (what's on the bus?)
• IRDA driver for 'NSC PC87108/PC87338' (is this onboard?)
• LCD (tm13264cbcg / mg1203d / ...)

There is no network interface available onboard, a USB network adapter is used.

It seems that Reciva used the 'bast' ARM architecture as a base for their own development.

"Bast is a modern ARM 920 board with a 266MHz Samsung processor. It has integrated IDE, USB, Serial, Parallel,   
audio, video, flash and two ethernet ports. This system has a good bootloader which is also found on the CATS 
and Riscstation systems."

System libraries + utilities

The following libraries and applications will be needed at least for implementing radio software:

• C-library (glibc/uclibc?)
• Flash write/erase tools: mtd-utils
• Shell + basic unix tools (busybox!)
• codec libraries (libmad, libogg, libvorbis, libflac, etc)
• Support for WLAN and security: wireless tools and wpa_supplicant
• networking libraries for HTTP, RTP, RTSP, MMS, etc
• Webserver (boa?)
• Preferably a scripting language for rapid development and CGI scripts. Lua, perl, ruby ?

'Radio' application

On top of all this, the 'radio application' will be running. This application might consist of various processes, daemons, CGI-scripts, etc.

The main functions will be

• Handling of the user interface: LCD, buttons and led's
• Network streaming + audio decoding. VLC for a quick start ?
• ...
