Sd Cards >1gb Work In Pdaxrom!

[daniel3000]

Hello,

Good news: The >1GB SD card driver from Cacko/Sharp (package zaurus-sd-driver-update-cxxxx_1.0+tetsu_arm.ipk, downloadable from this thread) works in pdaXrom 1.1.0beta3 too! I just installed it, then had to modify /etc/sdcontrol:

in /etc/sdcontrol change the line

Code: [Select]

SD_MODULE=mmc_pxa
to

Code: [Select]

SD_MODULE=sharp_mmcsd_m

reboot, and voila: My 2GB PNY card is mounted and usable.

I have not made many tests so far, so I cannot say anything about reliability.
I'll use it from now on, and report problems.

Other users have reported this driver to work in beta1 as well.

No guarantee, use it at your own risk!

As promised, the problem report:

No problems found so far!  

Using it daily and heavily, 2GB SD card continuously in the slot.
I had one problem (Input/Output error when acessing a recently created shell script). fsck.ext2 reported adeleted inode or something like that.
But I think this was doe to USB-storage access to the card via a Windows Laptop connected through USB while I saved that script. Problably nothing to do with the driver.

Wow, thanks for the good news!  I will buy a new 2GB SD card then (prices are dropping fast these days!). One thing: are you aware of any brand specific issue with this driver? Thanks!

No.
I use a PNY 2GB and a Sandisk 1GB card with this driver under pdaXrom and Cacko. No problems with these cards.

I think in the original thread about the driver (see my first posting) there is a list of tested cards.
Hopefully the driver will not make a difference in supporting cards when running under Cacko or pdaXrom ;-)

Well, one minor issue:
When shutting down the Zaurus via halt or reboot, I get a segmentation fault when the K96sd script is executed.
I haven't investigated further, becasue the FS is unmounted then anyway.
No idea if this is due to the new driver.

I've also been using this driver without noticing any problems.  (BTW, thanks!)  I don't reboot or halt very frequently, but I don't remember seeing the seg fault you report.

So far, I've been using an Ultra 2GB (not SanDisk Ultra).  With beta4, I had issues with my Patriot 4GB card, but I'm not noticing the same problems on beta3 with this driver.  I've been reinstalling and reconfiguring since moving back to beta3, so I'm waiting for things to stabilize before giving the 4GB a good workout.  Got my fingers crossed.

just setup beta3 with my 4 gig patriot.... I've only used it to install the hostap stuff, and as storage over usb to a windows box...so far, so good.

So the driver seems really working... I am considering buying an Apacer or BTC SD 2 gb here coz now they cost just USD 50. Hope they will work too.

BTW is there any speed improvement of the IO with the new driver?

Newegg has 4 gb SD cards for ~60 USD.  Newegg 4gb cards

I don't know, because I have not done any comparisons. So far performance of my PNY 2GB SD is fully sufficient for what I use it for.
I do not read / write large data streams which are time-critical.
The only things I do which could be faster (but I don't know if the card plays a role here or if the bottlenecks are processing power / USB interface) is compiling software and synchronization with PC using unison.

i also have this issue, the most simple method is not to unload mmc_block
what i did to fix this is
/etc/rc.d/init.d/sd line 38:
/sbin/rmmod sharp_mmcsd_m sdcardmgr 2>/dev/null >/dev/null

i also have another problem that my sd will not mount after reboot, i have to unplug and replug the sd to mount it.
and my fix is replace /etc/rc.d/init.d/sd 's start case with:

start)
    action "Start SD services:" /sbin/modprobe mmc_block
    /sbin/modprobe $SDMGR_MODULE
    sleep 1
    rmmod sharp_mmcsd_m $SDMGR_MODULE
    /sbin/modprobe $SDMGR_MODULE
    touch /var/lock/subsys/sd
    ;;

the method seemed silly, but it WORKS~!

I remember that I also has this problem. I simply solved it by adding a

Code: [Select]

/etc/sdcontrol changeto the end of my custom rc script in /etc/rc.d/init.d

I also observed that sometimes when I insert the card it is not mounted.
In order to address this problem, I have changed "sdcontrol insert" to "sdcontrol change" in the file /etc/hotplug/mmcsd.agent.

Since I did these modificatoins, I never had any problems with my SD card.
(except the segfault on shutdown, which didn't do any ham so far.)

Just install my sdcard package. It will cleanly uninstall the beta3 mmc driver and replace it with the Sharp SD driver. Of course, don't install the package from SD card directly
