Cowon D2

[shotofadds]

I crack open my 3-day D2+. Unfortunately I break the device's mic somehow.

I'm sorry to hear that.

PCF50635HN   (Is this one different from original?)

Well that's certainly different, but I can't find a datasheet to check any details. All the references suggest it's a smaller verison of the PCF50607, for which I can't find any details either. I guess I'll have to do some more investigative work when I get back from my holidays...

Have a good holiday!
I am looking forwards to the good news from you.

Also after massive searches, I also cannot find a datasheet of PCF506035 or PCF50607. Even the only datasheet of PCF50606 is from rockbox website. I will try to mail NXP semiconducts for the datasheet.

the "release events" patch is working nicely for me, the navigation is still a bit wacky from time to time, but it's a lot better now. thanks a lot shotofadds 

PS: I've noticed that the mayority of wrong presses are interpreted as "left" events... maybe implementing a self calibration for the resistive pad would be the best option, since resistive pads tend to vary their response/resistivity a lot.

Hey Guys!

Is it possible to use the "Touchscreen WPS" on the D2? If yes: How? Would it be good to set it as the "Standard WPS" for the D2?

bye, Vodi

There is already a calibration screen in Rockbox, but I'm not sure whether the D2 uses this..

Yes, there is a "Touchscreen Calibration" menu item in settings.

Jpeg resizing for album art seems to be messed up.
Take this 200px * 200px image, for example: http://rockbox.andrewbeveridge.co.uk/D2/cover.jpg

Rename to "cover.jpg", stick it in a folder with some tracks and play - it looks awful in the WPS compared to the same image in bitmap format: http://rockbox.andrewbeveridge.co.uk/D2/cover.bmp

Anybody have any light to shed on this?
I thought jpeg decoding was added to the core, so this wouldn't be a D2-specific thing, but after a brief chat on IRC it seems like it is.

When I get hold of a decent camera, I'll take photos to show exactly what I mean.

You could also use the System->Debug->Screendump feature..

I would, if it worked.
When it is enabled, and I connect my D2 to a usb port, nothing happens. I mean, no files are created.

It works fine in the simulator, but this problem does not occur in the simulator build.

Hello. Rockbox destroying FS on my SD card every boot. dd of=memcard if=/dev/sdd (before boot), dd of=memcarddestroyed if=/dev/sdd (after boot). Rockbox r22502M-090824 (own build and daily builds, d2N_3.59.bin), (card from Canon IXUS 85IS, 32mb)), photos: http://uploads.arago.shell.tor.hu/rockbox/1.JPG, http://uploads.arago.shell.tor.hu/rockbox/2.JPG
Lock pin is ignored by Rockbox, it destroy FS with lock and without lock very vell. On another card (SanDisk 2gb) Rockbox work good, but this card from digital camera, i don't want replace it from D2 to IXUS and back too often... And that microscopic card would be wonderful, bookmarks there preserve and so. Tried it when only driver written - then too dying.
I used many different programms for partitioning and formatting: fdisk+mkfs.vfat, gparted, acronis disk director, and even ms format... I tried to partition it as HDD or as megafloppy - all the same result (( Those images - fdisk partitioning and gparted formatting.
Sorry for my english...

32M memory card?! XD. I hope other people can help you.

Do You mean the donation?
It's not a capacity, 16gb NAND is enough for me, and 32mb SD more than enough for Rockbox until it learns to write to NAND. And buy SDHC with 4/8/16/32...gb I do not see the need, but SD with 512/256/128...mb - do not see the point. This card I got quite by accident, but since I have it - I would like to use it to benefit...

Are you shure that theese programms creates FAT32 file system on such small card?

No, they all says that it's impossible, FAT32 partition must be larger than 32mib. But for some IXUS-related reasons FS on 2gb card is also FAT16, and that card works normally with Rockbox, instead if this. I created FAT32 FS on card using dirty hack and got ATA mount File not found when booting. Card is not damaged, but Rockbox is not booting. Booted from NAND say that HD1 18.4mb/28.9mb, but not showing .rockbox dir on <microSD1> in file browser. This image.

Just to clarify: is your card being formatted as FAT16? Because if it's FAT12, that wouldn't work with Rockbox.
