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

OK. For the bitmaps, I forgot to say that you also need to change the following line in tools/configure (line 1056) from:
bmp2rb_native="$rootdir/tools/bmp2rb -f 5"
to:
bmp2rb_native="$rootdir/tools/bmp2rb -f 4"
You then need to do a make clean, then re-run tools/configure
But that isn't a solution - a version of Rockbox compiled with these changes will work on the type 0 LCDs, but won't work on the type 1 LCDs... What we (or rather someone with a type 0 LCD - I don't have one) need to do is to determine the lcd init sequence to make the existing code work again, and on all type 0 LCDs (i.e. including firmware version 1.0).

This indeed works. The RB bitmaps are displaying correctly now.
I've been poking through the code a little bit to determine what the proper LCD init sequence should be for type 0 LCDs. No luck yet, but I'll keep looking.
By firmware version 1.0, you're talking about the Apple firmware, am I correct? My 4G color has Version 1.2.1 on it, so this should be checked on various other Apple firmware versions.

Hi LambdaCalculus379
Is it possble to put the correted "0 screen" version up somewhere? I am not up to changing the code.
Friendly regards
Leon

I had the same problem with IPod Photo 20GB and could solve it with your hints. Thanks a lot for that.
If you need some information about my hardware or something else, just tell me where I can find it.
Have a nice day,

I have uploaded my build from this morning at http://www.chillt.de/rockbox.zip and will leave it up there for a while. This is a vanilla build with commit 17715 reverted. I have verified that this fixes colors on my type 0 LCD iPod Color/Photo.
