1Status so far
- Dec 22, 2004I've posted some info to the site, but I'm trying to keep some of it
out of the public eye for now so that the Zipit folks don't go
changing things before we get to do any updates.
What we know so far:
Chips (thanks ZipitPet):
+ Cirrus EP7312-CR-90 (CPU)
+ Agere WL600114LY (and shielded radio)
+ Hynix HY5V26D (16MB SDRAM, 16 bits wide)
+ MX 29LV160ATxBC-70 (2MB Flash ROM)
+ LPC915 (8 bit uP, with 2 A->D, for digitizer ?)
+ WM8751 (stereo DAC)
+ several smaller ones
FCC Paperwork (thanks coderextreme):
arch.cfm for FCC filing ID PPQ-WL100BA51
o I will post these docs to this group hopefully tomorrow (to save
Login procedure (thanks me, and coderextreme):
1. Zipit connects to tracking URL, e.g.
1.5 That number appears to be called the Zippy/Zipit ID (ZID) and is
not obviously related to the serial number or MAC address on the
device. Can be alphanumeric, and not all exist [process to register
new Zipit?]. 12345678.txt or any other 8 chars returns ZID not
found for example.
2. Text file contains what we assume to be a version number, and a
location to fetch a ROM version. We have seen version numbers 1.0
and 1.99 (00000000.txt) and ROM files bootrom.t2.1.0.bin and
bootrom.t3.1.0.bin. The .txt with 1.99 points to the same ROM and
hash, so we don't know what will happen if we faked our own ZIDs to
2.5. Also has what appears to be an MD5 hash at the bottom, though
they all appear to be the same and do not match with a hash of
either of the .bin files
3. Connects directly to Instant Messaging servers after initial
check with home server.
ROM .bin (general)
o Most likely encrypted as strings, etc. do not return any obvious
o 2MB + 16 bytes exactly is likely the full contents of the flash
ROM plus a 16 byte key?
o Two versions do differ (significantly)
o Video is flakey after disassembly and reassembly
o JTAG ports seem to have been removed from final production version
o Radio is not as strong as first hoped (34.6-38.9 mW) but battery
life has been better than expected
o FCC users guide implies that they've had streaming audio working
(by pressing ctrl-a). It looks like it will use Musicmatch Jukebox
as a local server much like the Linksys wireless media player.
o Several bugs and lacking features as documented on my page
ZIDs (thanks coderextreme):
-also working, I think these addresses represent Zipit ID numbers
for activated clients since the URL listing seems somewhat random
which makes sense because a bunch are probably not sold yet and
those that were sold were not sold in order.
That's about all I have for now... get cracking and sharing!
