Cowon D2

[shotofadds]

The dual-boot mechanism has changed to use the HOLD switch, because it seems the hardware will not boot from flash when any of other keys are pressed.

Press POWER for half a second (or less) then immediately set the HOLD switch. The Rockbox bootloader screen should then appear. If using Tcctool, ensure HOLD is set before uploading d2_patched.bin.

sorry, i read about this after my post... :\
great work!

P.s. i think that we should define in config:

Code: [Select]

#define BOOTDIR "/.rockbox"

You are making a great progress shotofadds, keep up the good work!   Thumbs up for other guys who are helping to make this port!
Last posts got me very excited and I would really like to test it on my D2/2Gb player. Unfortunately I don’t have any means to compile bootloader and patch it into OF. That’d be great if someone could compile bootloader and patch it into D2N.bin  for me. Any version of OF will do(2.5x/3.5x), I'm running v3.55 though. thanks in advance

here you go: 3.55 with newest bootloader http://www.megaupload.com/?d=0281CH8X

#define BOOTDIR "/.rockbox"

Yes, you're correct - I'll fix that. It won't cause any problems at the moment, since BOOTDIR is only used to check if the rockbox.iaudio file has been modified after USB unplug (and we have no USB support yet, so it's irrelevant).

[cybergrind]

Sometimes rockbox is crashed and when I power on player - have error (can't find rockbox.iaudio)

Error with HWinfo: it seems that when we press menu button -- emulates double click: we close HWinfo and then load HWinfo again =) you can see that in txt-file reader (first i see this problem in txt-reader: when you press menu button - reader close, because first menu item - quit) You can close HWinfo if you fast press menu+plusbutton (some trainings help you).

Question: we generate keydown and keyup events? keypress = shoud be keydown + keyup. or keyup shouldn't generate keypress event.

sorry my tangled explanations

Another way: define power button for quit

[shotofadds]

sorry my tangled explanations

No problem, I understand what you mean (in fact I listed the Hw Info problem on the Known Problems list on the wiki page). I fully expect to find more keymap problems like this. They will be fixed eventually.

The target-specific code in button-cowond2.c generates a raw 'snapshot' of the hardware button state at any given time. This is effectively turned into Key-down (press) and Key-up (release) events by logic in button.c, which is common to all targets.

The errors on startup (can't find rockbox.iaudio, read error, bad checksum) are unavoidable at the moment due to the unfinished NAND driver. To fix this, unzip the .rockbox folder to the player again and re-try.

Another way: define power button for quit

Yes, that is probably what I will do.

Thank you carsten. Wow, it works well. I can navigate the menu, browse files, view images and text files, run plugins, and beside invadrox there’s a chopper game quite playable too!

[stel]

When I try and use invadrox & a couple of the other plugins I'm getting Undefined instruction at 21F84220. Any idea what might be causing this?

Edit1:Also, when I try and run chopper I get Prefetch abort at 4000156A

Edit2: Thanks for the post below shotofadds. I compiled your latest update and installed. Happy to report its working as expected. I'll bare that in mind next time.

[shotofadds]

Try the standard "fix" of unzipping the .rockbox folder again. It's possible that the flaky NAND driver has loaded corrupt plugin data into memory.

EDIT: Also try the pre-built zip I mentioned here, just to ensure the problem is not something in your build environment.

EDIT2: I've now fixed the HW Info screen (use the power button to exit, just like every other screen does). And power off should work properly now. 8-)

Hello !
I'm glad to see that there are a lot of improvements

Is it possible to have a couple of screenshot, from text reading, or space-invaders?

You could send it to me, at "splitsch dot spam at gmail dot com".

Thank you very much !

I wrote a news about your progress on my blog, so the french community could read it, and I'd like to show people what has been done

You can do screendumps using the simulator as well, and it will show you the exact same screens/look as the actual targets use.

[shotofadds]

In response to a question on IRC (I have no access at work other than reading the logs), here is my current thinking.

a) There is no touchscreen support at all at present, apart from a hacky debug screen.

b) I intend to create a set of 'virtual' keys to emulate a 5-way D-pad using the touschscreen (as per Llorean's suggestion earlier in this thread): BUTTON_TSC_LEFT, BUTTON_TSC_RIGHT, BUTTON_TSC_SELECT etc. These can then be used for plugin button mappings, etc.

c) I think the lists/WPS etc should use 'real' touch buttons if at all possible, which may require some redesign.

Discuss....

[cybergrind]

IMHO:
Adding touchscreen support to themes is more difficult, but I think better than emulating buttons.
Touchscreen-buttons is good for some application - like text-reader, some games.

For fixing MENU button change keymap-cowond2.c

Code: [Select]

    { ACTION_STD_OK,          BUTTON_MENU|BUTTON_REL,     BUTTON_MENU },
    { ACTION_STD_OK,          BUTTON_RIGHT|BUTTON_REL,    BUTTON_RIGHT },

    { ACTION_STD_MENU,        BUTTON_MENU|BUTTON_REL,  BUTTON_MENU },
