Cowon D2

[darthvim]

Hi

i am using rockbox on 3 different sdhc-cards and it runs perfect, or at least nearly perfect
sometimes i've got the problem that i turn the d2 on and select a file to play but no sound comes out of the headphones. therefor i turn the player off and on again, after this precedure it works perfect...
if i found out when it happens i'll post again a message.

it would be great if i could be able to use the + and - buttons in holdstate as FF and REW (would save a lot of battery power using this buttons insted of the display ...).
i hope i didn't skip this adjustment in the settings menue.

darthvim, check out this thread on iaudiophile regarding buttons in holdstate for rockbox http://iaudiophile.net/forums/showthread.php?t=28467

Would someone run test_codec against all the files in this folder:

http://download.rockbox.org/test_files/

and then post the log file?  I'd like to see how we perform on various armv5 targets.

Is test_codec available as a plugin inside rockbox? I thought the D2 had a telechips or is that an ARM child too?

Yes, although you need to add "test_codec.c" to /apps/plugins/SOURCES.  Then it becomes available as a viewer. 

Telechips is the SOC vendor, ARM designed the CPU.

[Ezraghast]

so i need to compile a D2 build with test_codec.c?

Results are here:

Looking at my D2 build, it seems IRAM isn't used for codecs.  Is there a reason for this?  I see its in the lds file.

Hello I from Russia
I make out my cowon D2 + 16Gb
Here are my photos in high resolution
Hopefully this will help developers

Newer D2+ hardware revisions use an updated power management chip, and some
functionality is not yet implemented on these players (eg. touchscreen support).

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?

I just put Rockbox on my Newer D2+, the absolute pointing mode works well.

3x3 mode works well for me too. 

I know this isn't really a discussion/bug report thread but I've had a problem with the scrobbler plugin in all revisions I've tried to date: it writes the .scrobbler.log header to the file only intermittently. If a log is submitted and deleted, it seems the Last.fm Log playback setting has to be disabled and reenabled in order for it to be written again. This only matters when trying to use QTScrobbler of course or some other scrobbling client and the header is easily inserted but it's a little inconvenience I hadn't run into on other rockboxed players. Has anyone else experienced this? (I have a D2+ with patched FW3.11)

I have a D2+ dab with firmware 4.13
I can't find a Rockbox version for my player.
Will it ever come?

Frits:

First of all, ports aren't planned, they're worked on by interested individuals who own the hardware and are willing to contribute in some way or another to the project.

That said, it looks like the D2+ has been mentioned (quite recently) in this thread as working (at least for a couple people), so you could try using the D2 build (assuming that's the build these people are using) and seeing if it works on your DAP or not.

Be advised that the port is listed as unstable currently so things may not always work exactly as they should. Also, be sure to ask people for help if you have any trouble and describe your problems in detail.

Ahem.
Sorry, I'm not sure, where I should ask this. So...

Could radio frequency range be shifted down to 70 MHz?

I know that different region settings in COWON firmware answer for different radio ranges, IIRC, down to 78 MHZ. On the other hand, I don't know details about hardware limitations.

Hi Frits, look here http://andrew92.centelia.net/ to see instructions and links to the patched firmwares. Just make sure to check your FW version. You'll want to be using one 4.xx See here also http://iaudiophile.net/forums/showthread.php?t=25285

Hi Fullmoon. Did you try it in the hardware thread? According to the wiki the radio chip is the Sanyo LV24000. The main (or only) developer for the D2/D2+ is shotofadds and he or she seems to be absent for a while from here and from the D2 threads over at iaudiophile.
