Author Topic: I Mounted A 2 Gig Sd Card! (Read 215046 times)

Hello all,

I read each and every posting in the thread and (unless I missed something), it seems you all have a clamshell Z.

So, the key questions for me is:

Has anyone tried this driver on a stock SL-6000, with the Sharp ROM 1.12 and Linux Kernel 2.4.18? If yes, given the origin of the driver, would it mess up the built-in Wi-Fi configuration?

Thanks in advance.

I would like to purchase the C-Guys sdlink11b card to compensate them for their work, but the card seems to be out of stock. Are they still in business?

the c-guys driver is on my website in the downloads section, in 860 sub dir

thank you.

@GoLinux: I think that you should ask it in the dedicated 6000 sub-forum, if you want to have a 6000 user answer.

Thank you, Cyril92, I have regained access to my MMC card with the module that you provided.

On a related note, I asked the people at SPECTEC if they had a driver for one of their SD 802.11b cards for the Zaurus SL-C760. They did not, but they have a driver for a closely related 2.4.18 kernel for a Samsung handheld computer.

There was some discussion recently about a 2GB+ SD driver that was a disassembled and hacked version of the original Sharp driver, modified by someone in Brazil to work on the Zaurus SL-5500 models. Perhaps that driver might work with the SL-6000. The web page is:

I post this in another message, but I'll add it here. I don't recommend trying this sd module from the collie on a 6000. The 5000/5500 don't have a "standard" sd driver like the rest of the Z's. Search the forums. That's why OZ kernel's prior to 2.6 kernel were still using the original Sharp module or this one. And the rest of the Z's had a working SD driver in 2.6. I'm not a Z hardware expert, but I hate to see you lose access to your sd slot. I would think you'd have a better shot trying to c-guys drivers before trying to use the collie module. Take care.

Hmm. Accessing the SD card hardware on the 5500's may be different, but from what I understand the patch is at the protocol level which would be hardware independent. Hence, it would be possible to port the patch to the drivers for the later models.

I took a brief stab at this once - I know asm-fu, but at the time not so much SD-fu or ARM-fu. I might try again using this as a starting point... can someone post a copy of the 5500's original sharp_mmcsd_m.o for comparison purposes?

(yes, I know my 3100 doesn't need it, it's for the friend who has my old 860 )

Bring back to Ceasar what belongs to Caesar : you should thank speculatrix from zaurus.co.uk

the problem with the SL-6000 is that is uses the Toshiba Companion chip to do video (with acceleration), SD and some I/O glue. Thus the SD driver on the 6000 is completely different from the other models. Moreover, Toshiba have never released full technical specs on that chip - and at various times people with contacts at Tosh have tried very hard to get *some* sort of programmers reference guide.

I think because SD standard *was* closed, that Tosh felt impelled to keep the specification secret, and now that the chip is obsolete don't care any more that they could release it.

If you do have some way to contact Toshiba to get a detailed specification then there are many many of us who'd be very grateful.

Oh, and thanks for that.

BTW, it is very important that all Zaurus owners take good care of any downloads they make, since it is quite common for important resources to be abandoned and sometimes they are lost forever.

Even if you don't think you'll want it, try and get the source packages too. Disk space these days is practically free (as are blank DVDs for archives!).

For example, I found an interesting volume control applet for original sharp written by a third party, I managed to get the binary, but the guy had lost the source code in a disk crash, hadn't backed up, and also sold his Zaurus so had no way to recreate his work nor any particular interest in doing so (he wasn't unfriendly/unhelpful, just too busy)!

Thanks to all those that replied with some information on the SL-6000. I did post also on one of the SL-6000 specific forums. In fact, I found by chance this other thread. I saw the very short reference to the SL-6000 in DrWowe first posting but then all the rest of the postings focused on the clamshell models. Being this one of the General Forums and seeing all the activity DrWowe post generated, I figured I'd give it a try here as well.

I work in the semiconductor industry and I have tried too to find information on the Toshiba chip, so far unsuccessfully... Beside the SD limit, getting some info on the video section of it would help too with attempting a better acceleration.

I shall continue my quest.....

*spends a few hours doing clever things with disassembly*
*jaw drops*

The fix is really trivial - I think I can patch the 6000/c7xx modules no problem. (Yes, I have looked at the 6000 module internals. No, it is not dramatically different to the others.)

But it's a task for the weekend, I'm afraid - it's already 2:45am and I'm going to be regretting that tomorrow at work...

pelrun,

it would be great if you could do that! Unfortunately I do not have the necessary experience and knowledge to help, but I'm willing to try whatever you can come up to on my stock SL-6000.

Look forward to see more from you next week. And get some sleep...

I'm also looking forwards to a fix for the 6000 and so many thanks to you for all your work!

Count me in as a guinea pig to try your SD module.

GO... GO... GO... (cheering section)

You mean you can modify the binary module to support 2 GB SD-Cards? That'd be great, I'll test the one for the C760.

EDIT: Oh, and I've found the driver page, it moved to [a href=\"http://www.zentek.co.jp/sd/support/download/link_e.html]http://www.zentek.co.jp/sd/support/download/link_e.html[/url] since the old company apparently was bought by Zentek.

Ok, I've attached a test module for the 6000. No guarantees this thing will even insmod properly, let alone work. It's not like I actually have a 6000 to test it on...

Remember, it's only for older-style 2G and 4G cards. SDHC cards will not work. Also, remember to rmmod the original sharp module before you try this out.

EDIT: I realised this morning there's a bug in this, it won't work (it'll probably identify 2G/4G cards as just 1G.) Will fix tonight.
