Embedded Linux BSP supports Renesas SuperH reference board

Dec 2, 2003 — by LinuxDevices Staff — from the LinuxDevices Archive — 8 views

Lineo Solutions (Japan) has released a board support package (BSP) for Renesas Technology's SH4 2D graphics reference board (RTS7751R2D), targeting portable and car video players, wireless TV-phones, point-of-sales terms, and broadcasting systems for buildings, aircraft, and trains. The BSP is based on Lineo's uLinux Consumer Electronics Edition (CE Edition) distribution.

The BSP is provided as a plug-in for Lineo “uLinux Elite,” Lineo's embedded Linux cross development environment.

Lineo lists the following features for its uLinux CE Edition BSP:

  • Small footprint/Fast booting-time
    • ROM: 2Mbyte and above/ RAM: 2Mbyte and above
    • Kernel XIP support
    • ulibc: Reorganized and compacted glibc

  • uLinux Realtime
    • Hard Real Time in Linux kernel space
    • POSIX compliant pthread I/F specifications
    • Metrics Sample (Renesas MS7750R CPU Clock: 240MHz/Bus Clock: 60MHz)
      • Interrupt Response: 1.64 microseconds
      • Task Latency: 4.68 microseconds
      • Periodic Task Latency: 15.00 microseconds

    • Power Management Framework
      • Non-BIOS-based APM-related I/F support

    • IPv6 fundamental support and IPv4/6 support
    • Enhanced Memory Management
    • Lots of Device Drivers
      • HotPlug support

Lineo lists the following features for Renesas Technology SH4 2D Graphics Board (RTS7751R2D):

  • SH7751R (240/267 MHz), 64M SD-RAM, card-BUS, 2 PCI slot
    • FSB 120/133 MHz
    • FPGA (Lo-speed BUS split/True IDE/Touch Panel)

  • Silicon Motion SM501 (Voyager GX)
    • Embedded 2D video engine supporting 7-layered H/W frame
    • Dual display support (analog CRT, digital LCD)
    • I/O expansion for SH-4 CPU (USB host, AC97, I2S, I2C, ZV, GPIO)
    • Digital Video input 'YUV 4.2.2'
    • Lo power consumption (75mW @2D engine enable)

  • SD memory card support
  • 100 BASE/T LAN (2ch)
  • SH-BUS expansion for support external decoder logics
  • 12-inch SVGA TFT LCD — w/touch panel, AC97 codec (AD1885)
  • Debugger I/F (AUD, H-UDI)

“The SH4 2D Graphics reference board is fully equipped with such actual application oriented hardware as 2D Video Engine, 12-inch SVGA LCD with Touch Panel, 100BASE/T LAN Port x 2, and more,” said Akira Kobayashi, Executive Director, Engineering, Lineo Solutions, Inc.

“There are increasing demands to use Linux for digital consumer products with LCD supporting GUI operation with touch panel, audio/video playback, etc. In those products, an increasing number of the product developers tend to adopt embedded Linux that supports Realtime response and quick boot/shutoff capability because operability without being conscious of OS is crucial,” said Hisao Munakata, Senior Engineer, Corporate Business Strategy, Planning & Marketing Div., Renesas Technology Corp.
