Title: SL-C750 and PRISM3 chipset WLAN CF Card
Post by: JustAnother on June 10, 2021, 02:50:57 pm

Greetings! I bought myself a SL-C750 Zaurus recently, for playing around a Linux-based PDA, and immediately flashed it with Cacko ROM 1.2.3 Full (most popular and stable ROM for that model AFAIK). Almost immediately I found a CF WLAN card on Ebay and purchased it – model is Verifone WL-672 (rebranded Gemtek WL-672) but found that inside it has a Prism3 chipset instead of Prism2, fully supported by Zaurus ROMs. Of course, it's not working: PDA is recognizing it but as generic Intersil Prism2 card, not Prism3, and shows a yellow triangle in "System Info" app. AFAIK Prism3 chipset at the times of Zaurus' glory was found only with SanDisk Connect+ and old page from this site (via Archive.org (https://web.archive.org/web/20131110105809/http://www.oesf.org/index.php?title=Wireless_Card_Support#Sandisk_Connect.2B)) says that Prism3 should working as Prism2.x, but not in my case, I'm afraid. It is possible to make that thing work? Thanks in advance!

Hi,

Unfortunately, I doubt it, unless you know a lot about programming and even then may not work.

You should check the forum for posts about which cards are known to work.

Been awhile since I had a Zaurus, but think other issue you'll run into even with a Prism2 card is network security and whether it will work with WPA. Check that in posts too.

Best,

Mark

Thanks again, but actually I was able to make that thing work. It seems that this card is working with Cacko ROM – I'm just added it's entry to file hostap_fw.conf in /etc/pcmcia. Entry is gotten by console command

Code: [Select]

cardctl ident IDK if it matters, but I named my card as "Gemtek WL-672". Also I'm added a SanDisk Connect+ firmware to etc/firmware directory, file sf010704.hex, and installed sandisk-plus_arm.ipk. After this and a couple of reboots Zaurus recognized card fully and is able to made a connection. Unfortunately, Cacko ROM kernel not supporting WPA, so only the unsecured connections are recognized (made a access point from my Android phone).

Happy to hear that you have managed to make it work. It would be nice to have an updated Cacko with a more recent kernel, though I don't know if it would feasible.

Wow!

That's quite a feat!

Good for you.

Although not surprised about WPA issue.

Thanks for sharing.
