Ipod photo 40gb has bad resolution, all the colours are wrong

[AustinMarton]

Hi there, I have been trying to install Rockbox on my ipod photo 40gb (bought for this purpose). It is formatted to fat32, and the install has worked fine, but the colours are all wrong.
It looks like trying to display a picture with higher resolution than the monitor.

The colours are also wrong in Rockboy, instead of monochrome it's orange and black and white, it's kind of inverted looking. I have tried a number of different skins and the basic ones display fine (blue background black text) but no pictures or icons display correctly. Is there another version of Rockbox for ipod photo I could try? An older build? I tried to use the grayscale ipod version but it says bad checksum.

Any help or suggestions you can give will be much appreciated, I really hope I can use this instead of the apple firmware

Thanks,
Austin.

I would try extracting a fresh build.  Apparently it's not displaying bitmaps properly, but I don't know why this should happen.

[AustinMarton]

Hi thanks for the quick response. What do you mean by a fresh build? Do I need to compile from source? I've got the latest version of rockbox from the website.

[Chronon]

It's possible that some corruption occurred due to a bad extraction.  I don't really have a good explanation for what you're seeing.   Still, I think it's worth redownloading the current build and doing a fresh extraction to your player just to eliminate that possibility.

Does the Jpeg viewer work properly?

[AustinMarton]

Okay I have tried extracting and reinstalling and no luck (even on a different computer). The jpg viewer works but has the same issues with colours. Is there somewhere you can change the LCD screen type in the theme config files or something?

[MarcGuay]

I hate to ask, but have you checked to see if the problem exists in the Apple firmware as well?

[AustinMarton]

That's a fair point but yes I have checked and the colours work perfectly in the apple firmware.

I'm just trying to backup all the music off it now so I can try install ipodlinux and see if I still get the same problem, but this is taking a while since my ipod seems to unmount itself once I've copied about a gig.

Okay I have tried extracting and reinstalling and no luck (even on a different computer).

But did you download a fresh copy? Might be that you have a bad copy...

[AustinMarton]

Yep I have downloaded various fresh copies, even tried an older build but it did not behave any differently.

The ipodlinux website has been down for days and so I can't install that to see if it has the same problem! Could reformatting the ipod with the apple firmware updater thing be wise?

Going back to your original post, you said

"The colours are also wrong in Rockboy, instead of monochrome it's orange and black and white, it's kind of inverted looking. I have tried a number of different skins and the basic ones display fine (blue background black text) but no pictures or icons display correctly."

That makes me think that your problem is related to either a bad WPS/theme or incorrect installation. If you can post a sample screendump, it may give someone a clue what is going on. This explains how to capture a screendump: http://www.rockbox.org/twiki/bin/view/Main/ScreenDump

[Chronon]

Yes, a screen dump will give us something concrete to look at.  But I don't think it has to do with any broken theme.  It sounds like all image rendering is broken, as the user mentioned that the Jpeg viewer also suffers from the same defects.

It's a long shot, but try looking at the setting:

Settings > General Settings > Display > LCD Settings > LCD Mode

If it is set to 'Inverse', then that's your problem...

[Didgeridoohan]

Correct me if I'm wrong, but doesnt the LCD Mode only exist for players with a monochrome LCD? I know I don't have it on my H340 (only for the remote).

[bascule]

Well, I have it on my Sansa e200 and it does what it says on the tin, it just simply inverts all colours; menus, icons, WPSs, Album Art etc.

[AustinMarton]

Settings > General Settings > Display > LCD Settings > LCD Mode

Nope I don't have LCD mode in that menu.

I took a screenshot using the method described but asoundingly, it comes out looking perfect!? :S So I guess rockbox thinks its sending the right thing to the screen?



I will take some photos to show how it actually looks when I get home, but the ipod firmware still displays all colours and pictures perfectly, so I know the screen definitely is not broken.

Thanks again for your continued help everyone
