Cowon D2
Yeeze:
WOOHOOO
I got it compiled and I can see the usb connected screen =)
Browsing menus also works good!
Seems really nice...!
I will backup my player and then try to upload a completely flashed firmware using the usual update method
Yeeze:
Yeah it works!
Dual booting from flash...
OMG this is just awesome =)
A completely new world...!
Thanks shotofadds really nice work! Also thanks to all other contributors!
shotofadds:
If you're flashing the same version of the original firmware that you are already running (just patched with our bootloader) then your files & settings shouldn't* be affected. Make sure you only flash the new d2_patched.bin, don't use anything from the Cowon '0' or '2' folders.
*but still, a backup is never a bad idea. ;)
EDIT: Nice to see you got it working after all this time! You'll notice you can't do much at the moment, but still, some of the demos are cool and there's a Space Invaders game to keep you occupied...
Yeeze:
Yeah I already got caught in the space invaders game for like 20 minutes...
I should actually study history xD
The other demos are really cool too!
I noticed the debug screen got much slower... Is that because of the lowered cpu speed? Or is it that so much stuff is going on that this is fastest speed possible?
And the touchscreen input seems to be off when going near to the edges...
Can this be fixed easily? Well I think I will try play around a little with the touchscreen... Well lets see =)
Btw: Is the touchscreen now also timer driven? Or just the buttons?

It's neither: the CPU cache appears to be disabled in the bootloader (when enabled it gives roughly a 15x increase in speed, so that's the effect you're seeing). I added a note about this to the wiki Known Issues list just this morning.

There's not actually a touchscreen driver at all really, just a couple of lines of test code in the bootloader. Hence there's no calibration or jitter-correction whatsoever, so you get that slightly odd behaviour.
What you're currently seeing is not timer driven, but when the touchscreen driver is implemented "for real" it certainly will be.
