Rockbox Development > New Ports
Cowon D2
cybergrind:
power off code in SDK:
--- Code: ---..removed..
--- End code ---
I tried do almost all of this (except IO_CKC_SetClock), nothing good :\
Question: can we software-disconnect USB?
p.s. some info:
ARM926EJ-S (includes ARM Jazelle technology which enables the direct execution of Java bytecode in hardware)

Please do not post copyrighted code here, or in the tracker, or anywhere else - it'll be removed.
It may be the case that power-off does not work because we are running code in usb-boot mode. Until code runs from flash we have no way of knowing. This is something still to be investigated.

So... I will (hopefully) try to get the toolchain to work this weekend, since my brandnew D2 is begging for a working Rockbox. Don't know how much I will actually be able to contribute, apart from testing (unfortunately I have not much experience on embedded platforms), but we will see. First of all (before I put anything on it) I will read up on D2 desaster recovery, though :)
shotofadds:
Since you won't be flashing anything to your D2 at the moment (everything is done in usb-boot mode using tcctool), there shouldn't be any disasters to recover from.
I'm frustratingly close to a first working version (ie. booting to the menu with working buttons) but unfortunately I managed to leave my D2 at work and won't be able to make any progress for a few days. Oops :-\
Getting the toolchain to work should simply be a matter of checking out a current SVN build and running rockboxdev.sh - check the wiki for instructions. Hope it goes well!
ps. Experience on embedded platforms is mostly irrelevant, I had none before I started this port. ;D
luck3r:
Since I've checked out revision 16680, the screen of my D2 stays black with normal build, uploading the bootloader just loads the regular Cowon firmware after a short delay. Is this normal or am I doing something wrong?
