Présentation de OpenDingux


OpenDingux est une distribution moderne de Linux pour la Dingoo A320/A330. Elle utilise des interfaces standard de Linux, autant que possible, afin de faciliter le portage de logiciels pour OpenDingux.

OpenDingux à été créée à partir du travail d'autres personnes, surtout de Ignacio Garcia Perez (booboo), qui a réalisé le noyau Dingux, et Lars-Peter Clausen (larsc), qui a écrit la plupart des pilotes pour Qi Hardware Ben NanoNote, un dispositif qui est similaire en matériel pour la Dingoo.

OpenDingux Releases

About OpenDingux
OpenDingux is a modern Linux distribution for the Dingoo A320/A330. It uses standard Linux interfaces as much as possible, to make it easier to port software from/to OpenDingux.

Notice
OpenDingux is similar to the original (legacy) Dingux, but not 100% compatible. If older Dingux software doesn't run, please look for a more recent build/port of the same program.

Documentation
Read the About page on the Dingoo Wiki and the OpenDingux FAQ.

See below for developer documentation.

2012-06-16: First end-user release

The kernel of this release is based on Linux 3.4 and the root file system is based on buildroot 2010.11.

Changes

kernel:

  • splash screen
  • new mininit, compatible with more SD cards
  • scheduling options tweaked to get better performance
  • configurable color table for ILI9338 (can compensate for too blue screen)
  • don't monopolize CPU when initializing LCD controller
  • added support for V-SYNC (reduces tearing)
  • added support for more TV standards: PAL-60 and PAL-M
  • increased backlight frequency (prevents wavy backlight)
  • sound buffer size enforced to be a multiple of period size
  • easy-to-read console font

rootfs:

  • SDL updated to 1.2.15
  • SDL patched to support V-SYNC
  • added Python 2.7 and pygame
  • brightness setting is remembered
  • fixed issue where sound was off after shutting down with TV-out enabled
  • added menu-based TV-out configuration tool
  • added system information feature
  • added sound configuration tool (alsamixer)
  • show only graphical loading screen when loading apps
  • added htop (for developers; start via telnet)

toolchain:

  • upgraded GCC to version 4.7.1
  • improved default optimization: targets mips32 processor, tunes to mips32r2
  • link-time optimization (LTO) is disabled for now
  • enabled WCHAR support; this is one of the incompatibilities between legacy Dingux and OpenDingux, but it allows more software to be ported

Downloads

  • Kernel for ILI9325, ILI9331, ILI9338. Download the version that matches the LCD controller in your Dingoo. Rename it to zImage when you put it on your SD card.
  • Root file system. Rename it to rootfs.bin when you put it on your SD card.
  • Toolchain. You need this only if you want to develop for OpenDingux. The toolchain should run on any x86 Linux system (you might have to install 32-bit compat libaries if your Linux is 64-bit). Extract it in /opt and put /opt/opendingux-toolchain/usr/bin in your $PATH.

2011-09-18: Second developer pre-release

The kernel of this pre-release is based on Linux 3.0 and the root file system is based on buildroot 2010.11.

Changes

kernel:

  • fixed double buffering when TV-out is active
  • made framebuffer cacheable; this can speed up rendering considerably

rootfs:

  • changed supported image formats for SDL_image; fixes games that use JPEG images
  • added libmikmod and support for it in SDL_mixer; fixes games that use music in MOD or other tracker formats
  • many small improvements to gmenu2x
  • updated pwswd: kill active application using power + select
  • renamed TV-out configuration file: tvout -> tvout.conf
  • enabled memory overcommit; should allow more big programs to run

toolchain:

  • the rootfs that was compiled with GCC 4.6.1 malfunctioned, those problems disappeared when we reverted to GCC 4.5.1
  • enabled link-time optimization (LTO) in GCC

Downloads

  • Kernel for ILI9325, ILI9331, ILI9338. Download the version that matches the LCD controller in your Dingoo. Rename it to zImage when you put it on your SD card.
  • Root file system. Rename it to rootfs.bin when you put it on your SD card.
  • Toolchain. You need this if you want to develop for OpenDingux. Extract it in /opt and put /opt/opendingux-toolchain/usr/bin in your $PATH.
