Title: 2gig Sd On C700 In Oz 3.5.4 ?
Post by: gepeto on May 02, 2006, 02:52:55 pm
Hi ! I have a c700 for which I have just bought a 2gig Kingston SD card...

The card did not work (getting IO errors) so I brought it back to the store, thinking it was defective..

Now I have another one, and I have the same problem..

Buffer I/O error on device mmcblk0, logical block 0..


Is it a limitation of the hardware ? Of the SD drivers? Or did I just hit a model of SD cards that was not compatible with my device?

Thanks

You're not the first person I've seen mention that although I've yet to work out what the problem is. The changes in OZ 3.5.4.1-rc might help as it has a much more recent kernel with several MMC/SD changes.

Installed 3.5.4-rc2 and it now detects my card as 1.9gig free

Time to format it as ext2 and install some goodies on it..thank you very much!

good news - looks like 2.6 kernel support SD cards larger then 1G

Awesome... now does it support SDIO? Has anyone tried an SD WiFi card?

There is no SDIO stack for linux 2.6 and the 2.4 ones are all closed source.

Thanks for the quick reply.
Sad to hear it.
This beauty would have made a nice addition for many Zaurus users: [a href=\"https://www.oesf.org/forums/index.php?showtopic=19185&hl=]https://www.oesf.org/forums/index.php?showtopic=19185&hl=[/url]
(If it worked the way it is suposed to)
Sorry for hijacking the thread.

I seem to have problems with my SD..
Let's say I am downloading something to it using wget..

Wget just hung on me..
And if I just try to do ls in /media/card - that hangs too...maybe I should use ext2 instead of ext3 right? For speed...I just thought ext3 was a pretty good idea for removable storage..

actually the filesystem on your card shouldn't really matter (in terms of functionality), but ext2 is indeed the better choice because a journalling fs like ext3 wears out the flash much faster (and doesn't gain you any real benefits).

I ran a fsck on the card, fixed a lot of errors (probably from once when the zaurus hung for a reason I don't know) and now, it feels much faster , and I can use the card properly again...

Actually, someone on IRC just mentioned they were working on a SDIO stack for 2.6.  I think the spec got opened.

The problem is then obtaining the specs for whatever card it is you're trying to work with.
