source

I simply haven't the time to work on DGOS anymore, sadly. If anyone is actually interested I can disclose the source.

Current state:

• kernel
  
  
  • Multithreading & Multitasking
  
  
  • Protected memory
  
  
  • Code pages can be shared between processes
  
  
  • Support for kernel modules, including loading and unloading
  
  
  • Drivers for some hardware: HDD, flash, ram, timers, display, sound, touch
  
  
  • support for userspace applications & libraries
  
  
  • ARMv4 & ARMv5 support, including emulation of some v5 instructions under v4
  
  
  • Pluggable VFS & block device layer with NAND support
  
  


• Userspace
  
  
  • Heap code to support allocation & memory management
  
  
  • Ability to load dynamic libraries in ELF format
  
  
  • Currently posted libraries
    
    
    • libjpeg
    
    
    • libpng
    
    
    • zlib
    
    
  
  
  • New libraries:
    
    
    • GfxLib: load images in jpeg & png formats, show semitransparent layers onscreen, etc
    
    
    • RtLib: runtime for DGOS (VFS calls, other syscalls)
    
    
  
  


• PalmOS loader to run DGOS from inside palmOS

Work to do: wifi drivers (can wrap palmos ones), finish palmos compatibility layer, etc...

why DGOS?

I get it. people have moved on form palm devices and nobody cares. why go on? mostly because i want to, but also because palm hardware is quite capable still. i have a friend help me on some stuff now, to make things a bit faster. does anyone care still?

Android?

While playing around with Linux I accidentally made Android work on Palms. Is this of value to anyone?



UPDATE: "first success"

not dead

i promise this isn't dead. i still work on this. font rendering is still a huge pain in the ass! :)

where i've been

WHY haven't I updated the blog?
I've been working hard on this: http://www.kno.com

lack of time

working in a startup, i have very little time lately, sadly.

still working on this once in a while though...

My messing around with FAT code broke fat12...fixing it
