It does work with Cacko 1.23 provided you have the original SD card driver and not the 4GB SD update.

However, the change to supporting SDHC has had some side effects for me:

It has made the Z much more sensitive to SD card timings - so some cheap SD cards give timeouts (type "dmesg" in Konsole to see the messages)

It seems to expect the SD card to be partitioned since it tries to automount /dev/mmcda1 rather than /dev/mmcda

MMC card support seems to have gone - can't get any of mine to mount

Doesn't Cacko have a special driver for SD cards (up to 2GB IIRC) ? Have you remembered to remove it ?

i cant remove it i think, and i solved the problem installing tetsu kernel and modules before applying the SDHC ipk.

i really havent used an mmc on my c3000 yet and dont believe its going to happen, then it doesnt bother me.
the timeout messages are prompted with the original driver too, at least in cacko 1.23b1 on my c3000.


Thanks both for your responses!!!!
happy to see there are some Zīs users active on this forums.

Glad to have been able to help.

Anyone who has experience with this SDHC driver (i.e. installed it but had to do something to make it work) please consider improving the wiki article at http://www.oesf.org/index.php?title=Drivers

The point is I'm seeing timeouts for cards that did work with the earlier drivers - but only the cheapies so no great loss.

I just installed the SDHC driver on my SL-C1000 and retired SL-C860 and it seems to be working fine. This will really extend the useful life of my Zaurus since it has become impossible to find any of the older SD cards that will work on the Z.

What size card did you try?

(From what I could gather from the original link to the ipk, it looks like this driver supports upto 32GB cards! That is really amazing.)

I believe you can still find the "old" SD cards on ebay. I bought a 4gb Transcend x133 speed there.
Meyer
What I meant by "older SD cards" was cards on Sharp's old verified support list, which hasn't been updated in years and lists no cards larger than 1GB. Before I installed the SDHC driver, I couldn't use any SD memory cards that didn't appear on the list.

I saw that this 16GB Micro SDHC, Class 4 card is currently on sale for $20 (with coupon code EMCKBJJ33 ) and free shipping.

Does anyone know if the Zaurus SDHC driver would/should work with this card? (using a SDHC adaptor, of course)

The driver homepage says "SDHC up to 32 GB", so it should work.

SDXC seems to be the same hardwarewise, but I guess the driver needs to be modified for the higher capacity, and the Zaurus doesn't know the default exFAT filesystem on those.
Meyer
With the SDHC driver on my SL-C1000 I have tried a range of SD and microSD cards of capacity from 128M to 4G (4G SDHC card purchased yesterday for 500 JPY = 6.51 USD) and have yet to find one that WON'T work. (Some require the Zaurus to be rebooted to detect the card. I have yet to determine the cause of that. File system type?)

I was about to start a chart in the wiki of memory cards supported by the SDHC driver, but now think there's not much point with that kind of success rate.
