Title: Sd Wireless?
Post by: muramas on April 20, 2005, 09:13:44 am

Hi all.

I just finally ditched my aging SL-5500 in favor of a brand new SL-C1000 (it is, btw, awesome .

I have heard some rumors that unlike the original Zauri, the newer clamshell models actually have SDIO capability (eg. for SD Wireless cards).

I need a new wireless card, and I'm considering one of these SD Wifi cards (Socket has one, and Sandisk has a dual Wifi/Storage model that is very tempting..)

Has *anyone* gotten SDIO working on a Zaurus?  I'm an experienced Linux user, so I don't mind putting in some effort to get it working... but I'd like to figure out if its even possible before I start wasting my time/money..

Any thoughts?  (TIA..)

The Clamshell Z's may have a limited form of SDIO, but there are only 2 known devices that support it - an AirH cellular card (only usable in Japan), and the C-Guys SD Wifi card. The C-Guys card has a driver that can be described as Beta quality at best - frequent disconnections, etc. (Plus it doesn't seem to work at all with Cacko on the 860 - only Sharp). Forget going SDIO and stick with CF cards for connectivity.

Thanks for the quick reply; I'll do that for now.

Any recommendations for low-power CF Wifi cards?  (I haven't been following the Z for a while now, and most of my bookmarks no longer exist :)  There used to be a compatibility matrix for CF cards out there somewhere..

The Socket cards used to work, IIRC, but I have read in various reviews that the new model (ie. the WL6004 line) doesn't work on the Z..

Anyone tried the AmbiCom WL1100C-CF?  Or other recommendations for low-power, smallish CF Wifi cards?  (I have a Linksys WCF11 atm, but it sticks out a little too far and uses too much power to be ideal.)

(I'm still hunting myself.. I'll post an update if I find something good..)

The C series do have SDIO, that has been proved. The problem is that any SD operations are classified information and hence no linux driver exists. SD cards on the C series are operated using a MMC driver...  So the problem is that there's no way to code a linux driver for sdio perhiperals because to get the information you need to pay fees and sign a NDA to get at the documents!

About the compatibility matrix, that would be great. It's on my list of things to do during the summer to help out. I've been watching and waiting to get a CF card for quite a while now and I have no idea what is best but there are a lot that do work (except 802.11G cards) but no clear information about what is better.  Anyone got any definitive guide?

A few links I've found..

https://www.oesf.org/index.php?title=Wireless_Card_Support (https://www.oesf.org/index.php?title=Wireless_Card_Support) is a good start... could use some filling in/filling out... and pics would be great (often times I would guess physical profile is an important factor for Z users..)  More cards would be good.. more feature columns (ie. protocols A/B/G, WEP/WPA, etc.)..

A general (but slightly out-of-date) matrix of range/power/notes (from the original zaurus.com site): http://www.ossh.com/zaurus/mirrors/docs.za...lesscards.shtml (http://www.ossh.com/zaurus/mirrors/docs.zaurus.com/wirelesscards.shtml)

I think I'm going to grab something soon (Ambicom, Belkin, or maybe Pretec).. we'll see how it goes..
