Cowon D2

I'm sure one of you guys has figured this already, but looking at the firmware disassembly, the SPI interface to the LCD is accessed by writing the following bits to either 0xF005A028 (to set the pin low) or 0xF005A02C (to set the pin high):

bit 24 = /CS
bit 25 = SCL
bit 26 = SDI

Register and data pairs can then be written as per the diagram in section 6.1 of the LCD datasheet. This would allow us to perform the power-on and power-off sequences given in section 9.

Establishing how RGB data is transferred is another matter entirely though...

First of all, I got the recovery drivers, so if anybody already bricked their device tell me =)

Further more, after mkdf posted he got the firmware loaded on the D2 using tcctool with Gentoo linux I tried to get it working under ubuntu, but no luck, do I need to change the value in the source of tcctool, or what did you do to make it work?

And what can I do, if I got tcctool working?

Hello,
first of all thanks for the efforts already done by so many people. For me as a 'beginner' reading your posts is entering a different world behind the UI.
Neverless I have a bricked D2 (4GB) as well. After a failed F/W upgrade (-> 2.51) it doesn't start up anymore. It also not recognized by my Ubuntu system or windows. But I can find the bugger with lsusb -v, as it is mentioned earlier in this post.
As I mentioned I'm running Ubuntu and therefore I couldn't so far get tcctool working as well. Is there any update?
@Yeeze: can you provide me the recovery drivers as back up, in case there is no running tcctool in the near future? Thanks.
Perhaps this is not the right place to ask for this, but this post is the best I could find, which might help me out.

Thanks anyway for sharing the knowledge.

Please don't turn this thread into a general D2 troubleshooting discussion - it should be limited to discussion related to porting Rockbox.

Discussion of the use of tcctool to help recover broken D2s is happening here:

ok, thanks for the notice

Tcctool works on a bricked D2.

I bricked my D2 on purpose and was able to recover it using Tcctool.

I used the Windows version.

Thanks Linuxstb for a great tool.
