Bootloader

No information available yet. Redboot ? u-boot ?

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.


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?)
  • Preferalby 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
  • ...
