Cowon D2

[tails_]

Hi. I have 8GB D2+ and have 2 small issues:

1. Charger status is always absent
2. touchscreen problem:
    then you touch screen near edges it detects touch first in that place and then upper\lefter\downer\righter for about 15-30 pixels

P.S. Is USB mode still being developed?

hi, i just updated my rb to r28368 because my old installationd coul not read from the memory disc rb was installed to after it started from that disc flawless.

anyway, i do have some nasty problems with the new verstion.

the most annoying one is related to volume controls.

with most tracks, volume control will work fine
with some tracks, volume controls are a bit disturbed, like with some sudden balance l/r and / or volume jumps.
with some tracks, volume +/- wont do anything. going to settings -> sound settings -> volume and changing the volume there will reliable make my touchscreen inresponsive so ill have to restart the player to fix this.

a second problem is, that sometimes when i try to start rb ill get an checksume missmatch error and rb shuts down immidiately.
in this cases, ill have to copy over a fresh rb install to fix it.
this problem occours often after i booted into the original fw and have had a database  rebuild there.

Today, after not haven't used my Rockboxed D2+ for some time, I installed the latest version of Rockbox on the SD card. To my surprise however, every now and then my player doesn't boot properly. I see the Rockbox screen for a few seconds and then my screen turns bright and is frozen. I can only use the reset button then and start again. One time it does boot then, but another time I get the same problem. It is very randomly. I didn't have this problem before. Until the last time I used the player ( a few months ago) everything was o.k.
To exclude that it has to do with the SD card, I also tried another card but same problem.
When Rockbox does boot properly I see a short "flash" between the initial Rockbox screen and the final screen. I don't know if this is normal.
What could be wrong or what could I be doing wrong ?
FWIW, I have FW 3.13 installed.

I'm having a similar problem, where I had an older version for a long time with no trouble and the new release is breaking it.  For me, it will sometimes boot correctly but other times will go from the rockbox bootup screen to a black (blank) screen and will stay frozen until it either decides to let me reboot it (also happens in a random period, sometimes is seconds, sometimes is never) or until I plug it into USB.  I have an original D2 but it's running D2+ firmware 2.13.  I am running rockbox from an SD card, but have been doing that for some time now with no problems.

Guys, try this version http://www.megaupload.com/?d=41QHGF6S  from shotofadds` post http://forums.rockbox.org/index.php?topic=10164.msg171379#msg171379

Thanks mbk1969.
The link you provide seems to be the version 1 in shotofadds post, whereas I understand from that post that version 2 is the one that works correctly.
Am I right and should I try the other one, version 2 ?

Btw, I luckily had a backup of the version I used before (r24332-100124) and everything is fine now again. However with that old version I cannot use a lot of new skins.

Update: I tried both versions meanwhile.
-Version 1: 25 boots, no problem, working fine
-Version 2: 15 boots, 3 times bright screen and freezing
So it is version 1 I need apparently and accordingly to your reply above.. That would be contrary to the post that you linked to. Am I right ?

[motorbit]

thank you, mbk1969

both versions refused to start as soon as /.rockbox/tagnavi_custom.config was present. modified tagnavi.config works fine.
database still is pretty slow with my monster 200+ tracks albums, but i guess its the weak d2´s processors fault and i can live with that one.

v2
-refused to start up once, showing me some thin, horizontal, fast up and down moving white lines on a black background. had to use the reset button to restart.

-when increasing / decreasing volume, sometimes i will have one speaker muted. upping/downing volume for just one press always fixes it, and muting wont come back when i undo the last change. this happens quite regularly, like 2 -3 times when upping from  -70 to -15
note: this is NOT the new muting i had with the newer rockbox builds. i always have had this phenomena happening with rb, ever since i first used it and its not a serious problem at all for me.
aside of this, this version running fine.


v1
i didn't tested it long enough to be sure but it seemed to work correct.
anyways,  from all i read persistent muting issue may not be fixed with this version.

ill test v2 for 1 more day, than i will change to  v1 for  2 days  (or until i run into serious problems).
i will report back than.

Sorry, I missed the link - supposed to give the link to version 2 because it works fine on my D2+. And I am glad that you`ve tested both versions. Best practice ever! =)

[franky]

Same for me. I compiled yesterday the latest svn tree (r28478) but after the booting screen the D2 just froze. Not always, but maybe 3 out of 4 times or so. v1 doesn't do that for me, i haven't tried v2.

===EDIT===
Removing MCFG |= 1 helped, i could run my own compiled version now.

Concerning the question whether V1 or V2 is eabi... I do use my own bootloader which was compiled with eabi. Is this maybe the key why some people can run v1 and others v2 without problems?

I flashed my new D2+ with RB yesterday & I can confirm new build issue (after star screen D2 froze). V1 works fine for me, I didn't test v2.

First of all: BIG THANK YOU all involved, original FW is just pathetic and Rockbox totally supersede it.
(I'm familiar with RB for a long time running it on my X5L)

I've got one question:
I can't get how to set up time in Rockbox. In original FW I sat up the right time, but RB got different one and I can't find the way to solve this. Maybe it isn't implemented yet? According to the shotofadds post on iaudiophile forum time should work...

I am stupid, I was looking for it at settings/general/system...  Thanks a lot!

Hey, it seems that the latest build for the D2, r28538, works fine again.
I booted 25x subsequently and no bright or black screens and no more freezing.

Hi everyone,

First of all : congratulations to all developpers for this great software, it really boosts my cowon D2 functionnalities.

My comment about Ton's problem : I had the same annoying bug since a few versions of rockbox, my player started and then a black screen appeared. I had to restart it three or four times so as it eventually worked. This morning I installed a new build 28546 and tried it a couple of times : no problem at this time, everything seems to be ok, no flash, no black screen anymore.

Don't know in which build It was corrected (can a developper tell me that ?) but it seems fixed.

Thanks again, in the name of all Rockbox users !

dunno...
still having some major problems aside from not booting up sometimes.

worst for me:
when playing high bit rate ogg´s (500kbps)  will make the volume control irresponsible with enabled equalizer. this is happening with all recent versions, and with both r2800 versions.´m pretty (but not 100%) sure this problem was *not* introduced when the latest codec optimizations of r24XXX. i rather guess this problem may have been introduced when the volume range was increased to -90db.

i think there may be one other (not to serious) problem  that  could be common to all never versions that lead to hard crashes of rb so the player has to be reseted with the reset-button. this happens verry rarely, and so far i was unable to provoke this bug reliable but plugging or unplugging the usb connection seems to trigger it.
