Sansa Clip Zip
2facedmayor:
Hey Bertrik, thanks for all your great work on the Zip so far.

I just test drove Rockbox on my 4 GB Zip and had both of those problems. There was either an excess of blue or an absence of yellow on my display, but I could normalize it somewhat by resetting the colors.
Can't speak for why the track delay is happening, but I tried shuffling all of my tracks and there was a good 5-6 seconds before each one started when skipped.
I used the current build (r30890), the Win32 version of mkamsboot, the 01.01.17 OF and the pre-compiled bootloader which dfkt made available here: http://www.anythingbutipod.com/forum/showthread.php?t=66292. I would have compiled the bootloader myself but, as far as I can tell, no "bootloader-clipzip.sansa" file has been released yet.
What could I be doing wrong?
bertrik:
Actually, the colour problem and the playback delay problem should both be fixed now.
Album art colours seem a bit washed out, but that's just a hardware limitation I think.
(Although maybe we can adjust gamma for to adjust the subjective contrast?)
The Clip Zip can have two different kinds of display, so far we've seen only the Visionox type (visible in the diagnostics menu of the original firmware flashed with a 'T' suffix). The other kind (WiseChip) has not been seen yet 'in the wild', but there is a driver for it. If/when the newer display type shows up, it will probably not work completely right.
BigPapi:
There is no playback delay on mine, and the colors are OK, asides from what Bertrik describes as a slight washing out. I'm also on r30890 and using the bootloader dfkt shared. The only issue I've seen was a couple of freezes upon disconnect from the computer, although that may have been caused by a corrupted file that I've since removed from the player.

That would explain it. I have one of the WiseChip players. I confirmed this by running a diagnostic, as you described, where I saw this on the second page:
[HW Info]
FM SI4702
WiseChip
Since I, and others with the same display on their Clip Zip's, will undoubtably run into trouble running Rockbox, I'd like to help. Are there tests you could have me run on my device?
bertrik:
2facedmayor, for the Visionox display (which I have myself), I noticed that blue and red were swapped, can you check if this is the case for your display too? To check, go to Settings / Theme Settings / Colours / Background Colour and verify that the top bar (R) is indeed red, and that the bottom bar (B) is indeed blue.
Also, I may have made an error in the lcd initialisation sequence, I can double-check that.
