Change made in r17715 messes up screen colors on iPod photo, especially noticeable in themes with photo backgrounds.

Colors appear jumbled or swapped, i.e. white becomes green, etc. Initial Rockbox boot screen also appears jumbled.
This task depends upon

I have this same problem are all the latest versions doing to you too?
Comment by Chris (Veloz) - Friday, 20 June 2008, 21:26 GMT
Yes, at least all of the ones I tried Monday, until I got back to r17714. I have not updated since then. The latest release I tried was r17727. I think I'll wait to see some adjustments to the display code before updating again.

Ok well i will leave a comment when they got a release that works i get on every day and update it to see if it works correctly and currently on like version 17756 i think and it still is like that

I too have this problem. And I'm grateful for the knowledge of which builds are and are not affected. I'll continue to run r17714 until this is resolved, because Rockbox was utterly unusable with this bug; the screen was horrendous and unreadable in all but monochrome themes.

I also notice the release notes for r17715 state that some code was "blind-copied" from iPod linux to resolve another bug with colour display. It would seem obvious that this is what has broken it. Are there iPod colour/photo users who aren't affected by this issue?

Daniel i just noticed that too i was reading through the IRC on june 19th someone was talking about it and they said that exact same thing it was between 17714 - 17715 that they got codes from ipod linux

If you would like the lated working version download this:


PS im still working with the latest versions to see if they work

Yes, I'm certain that it was that "blind-copied" code that caused the problem. Although, I do find it interesting that the log entry states that it was introduced to FIX a display problem that we (iPod Color/Photo) users were experiencing. However, I was not experiencing any display issues before the addition of the r17715 code.

This makes me wonder if the issue is with specific hardware revisions. I have an iPod Photo 60Gb.

To those that have responded: which iPod do you have?
Comment by Daniel Beardsall (Beardy) - Wednesday, 25 June 2008, 18:02 GMT
It does seem to be the obvious cause. Mine's an iPod photo 30GB. I also had not had any display/colour issues prior to r17715.

hey theyve already provided a patch for this

i took the time to compile it into the r17804 version soo here it is

heres a rapid share link
Comment by Daniel Beardsall (Beardy) - Saturday, 28 June 2008, 21:57 GMT
That link doesn't work for me. Where did you find this patch?
Comment by Adam West (xxbatman94xx) - Sunday, 29 June 2008, 00:41 GMT
Heres the link to the patch

but you gotta compile you own build for it so heres the link to the compiling guide

or you can just download it from rapidshare and extract it to your ipod
Comment by Daniel Beardsall (Beardy) - Sunday, 29 June 2008, 01:15 GMT
I see from the patch notes that mpegplayer still won't work with the patch, so I'll stick to r17714 until the official build is fixed. Thanks anyway. At least now we know what's gone wrong.
