Sansa Clip Zip
saratoga:
The Sansa Clip Zip is the Sansa Clip+ replacement. Like the Clip+, it is based on the AS3525v2 SOC as can be seen by checking the AMS header on the firmware file:
http://mp3support.sandisk.com/firmware/clipzip/clipzip01.01.12.zip
The format does not appear to have changed significantly, as amsinfo happily unpacks the firmware revealing nearly the same firmware contents as the Fuzev2, with the addition of a few extra decoders and such. Since this appears to be another SansaAMS device, lets reuse that wiki:

Theres also some hardware information here:

I'm too busy these days to contribute much to a port, but if someone else wants to take the lead on this I might be willing to chip in a bit.
yelped:
Excellent news! I was about to start searching whether it was based off STMP3780 like the Fuze+, or like the AMS Sansas.
This means that SQ is exactly the same as the Clip+'s excellent SQ.

Anythingbutipod has a nice comparison between the clip+ and the clipzip: http://anythingbutipod.com/forum/showthread.php?t=64913
The relevant differences with the clip+ so far seem to be so far just the different display and RDS support.
The display is a 96x96 pixels colour LCD and in the abi article it shows some horizontal lines around high brightness features of the screen, which could point to it being a passive matrix lcd like in the sansa c200.
The radio has RDS support, possibly they are using a si4703 variant instead of the usual si4702 tuner chip (just a guess so far). Oddly I don't see a mention of RDS in the sansa clip zip user manual or on their product page.

Just letting you know that I am starting to create a basic framework to build the clip zip as a target for rockbox (to get something compiling, not working yet).
bertrik:
Ok, a basic framework has been committed. This makes it possible to at least *compile* a bootloader for the clip zip. The driver for the LCD and backlight is still a stub (i.e. empty functions). The driver for the buttons should basically work except the GPIO-to-button mapping is probably wrong (so UP may be LEFT, etc.)
I also updated mkamsboot to recognise the original firmware file for patching it with the rockbox bootloader. You can't actually create a flashable firmware yet because the dualboot part is still missing. The dualboot code is the code that checks a button/USB connection to decide whether either the original firmware or the rockbox bootloader should be started. This is tricky stuff because any error in this part can potentially brick the player so any new dualboot code needs thorough review.
Marvin the Martian has posted some screen shots from the diagnostic menu on the clip+:
http://www.anythingbutipod.com/forum/showpost.php?p=571421
This basically confirms that 1) diagnostic menu is still available 2) the DRAM memory configuration is the same as on the clip+ 3) it still uses a silabs tuner (si4702 or compatible) and 4) apparently the internal name of the hardware is "visionox".
The clip zip appears to support RDS, so perhaps sandisk put in an si4703 tuner chip. This is basically a si4702 (which we already support in rockbox) with RDS capability added.
