Osprey

The Osprey is NEC's reference design for the Vr4181, originally aiming at the Windows CE market. It comes in a PDA-style, clear plastic case which gives it a geeky, cool look but to be used for development the case and the flash module need to be removed to access all the the debug connectors on the board. It features:

• 240 × 320 Pixel colour TFT display with backlight
• 4 buttons.
• serial port
• audio input / microphone connector
• audio output
• a compact flash socket
• a debug serial port
• a debug EPROM
• a connector for the flash module
• 4-digit 7-segment LED display
• connectors for logic analyzer probes
• an NE2000 software-compatible National Semiconductor DP83905 Ethernet interface

Linux support

Linux 2.4 supports Osprey. Linux 2.6 did as well, albeit with some bitrot until in 2.6.12-rc5 on 2005-06-3 support was removed.
