No not yet. I'll try and do it soon, but I haven't really had much time for Rockbox work recently.

Color depth of Cowon D2's LCD screen
According to JetAudio's web site, the LCD screen is 24-bit (16 million colors), but the D2's configuration file contains the following line:
--- Quote ---#define LCD_DEPTH 16
--- End quote ---
I wonder why this value is not set to 24. There is no other player whose LCD_DEPTH is >16, therefore it could be that Rockbox does not support higher values.
I would be glad if someone can clarify this.

You said it. There's no 24-bit (RGB 888) LCD driver in Rockbox, and there wouldn't be a huge advantage writing one just for the D2, since according the LCD datasheet it is actually only 18-bit. Cowon's UI also uses 16-bit, btw (although it's possible it achieves a higher depth using native YUV mode for video playback...)
Josef K.:
I'm planing to buy D2+ (I'm afraid it'll be unavailable soon).
--- Quote from: Wiki CowonD2Info page ---Newer D2+ hardware revisions use an updated power management chip, and some
functionality is not yet implemented on these players (eg. touchscreen support).
--- End quote ---
So my question is: is there a touchscreen support (3x3 Grid mode) in Rockbox for newer D2+ version? And, if it's not, is it still possible to use Rockbox just with DAPs buttons?
Thanks a lot for an answer!

No, no-one's working on it now. I've spent months looking into this, and in my opinion providing write support (compatible with the Cowon firmware) would require a collossal amount of further effort, and we would almost certainly fall foul of some FTL-related patents.
The current situation of booting from an SD card works perfectly well for me, and from the lack of complaints, it seems the majority of users don't mind either. The only difficulty I am aware of is that RbUtil doesn't know about the need to unzip .rockbox to the SD card.

Then if we make RbUtil automatically detect and choose the SD card as the installation point (if no card inserted it would prompt the user), then can we declare the D2 as a stable target? The touchscreen is ugly and unintuitive to work with at the moment, but it does work and provide full functionality. I really like to see this platform getting stabilized :-)

Hi developers !
I am using Rockbox on my D2 since the time it's able to write on the SD card (even before that).
I used to install from svn and everything was fine. Then last time I update from RButil to see what was going on there...
Wow ! I installed themes and all... I must say Rockbox make my D2 really better !!! Compared to OF, among others: easier to use (in general and, particularly playlists), giving a better database management, a real "resume play" on start up, nice usable themes ! At first I thought I would miss the "absolute point" touchscreen mode, but this touchscreen, being relatively small, is more functional and easier to use in 3x3 mode.
Thanks, great work !
