[SOLVED] sd card (mmc) not recognized
  • monzmonz March 2010
    SliTaz does not see a SD flash memory card (the kind used in digital cameras) when i insert one into my Toshiba Satellite Pro A215-S5850. I am able to see and mount the card when booting into Linux Mint (i.e., Ubuntu) on the same machine.

    Also, I normally use SliTaz on my eee-pc, and it is installed entirely on a SD-card, and works with no problems. I even have GRUB installed on the "MBR" of that SD-card and set the eee-pc BIOS to boot from it, entirely bypassing the original Xandros Linux installed on the machine ... but of course i have Xandros available on the GRUB menu if i want it.

    Any solutions to get the card seen and mounted on the Toshiba? This is a rather large version of SliTaz (1.8G in a separate /usr partition and 1.5G in the partition holding everything else), with lots of tools installed, and it surprises me that i have this problem.

    Can anyone help with this? I installed the linux-mmc tazpkg, but there is no /dev/mmcblk0 ... no mmc anywhere in /dev/.

    I see that /etc/udev/rules.d/60-persistent-storage.rules is where the udev is supposed to create the mmcblk0, but it is not happening on my machine.

    the card reader is detected from the kernel? is it on the usb bus? is it a multicard reader? output of lsusb it it's usb?
  • monzmonz April 2010
    using grep i found that my card device appears here:


    # pwd
    /sys/devices/pci0000:00/0000:00:14.4/0000:14:06.1/mmc_host/mmc0

    You can see that the MMC reader is listed under lspci, not under lsusb.

    Under dmesg you can see that it says the Ricoh controller disables the driver. What is going on there?

    PS - What is the proper way to quote code here in the forum?
  • erniaernia April 2010
    this
    http://cateee.net/lkddb/web-lkddb/MMC_RICOH_MMC.html
    should explain what's going on
    does it works modprobing:
    mmc_core ricoh_mmc sdhci-pci sdhci
    ?
    to quote code you use
    < pre >text< /pre >
    with no spaces inside tags
  • monzmonz April 2010
    hi ernia ... so then it is correct for my driver to be disabled, right?

    I did not try modprobing those modules, because sdhci, ricoh_mmc, and sdhci are all set up to be loaded automatically in my /etc/rcS.conf ... i never put them there, so SliTaz did that on its own. And lsmod shows that mmc_core is also already loaded.

    So i'm still confused ... why does this machine not see my SD card? Also, i should note that # grep mmcblk0 yields no result.

    try 
    modprobe mmc_block
    .
    what's the output of 
    tail -f /var/log/messages
    when you insert your sd card?
  • monzmonz April 2010
    Ah ... thanks, ernia! ... # modprobe mmc_block did it!

    Does that have to be added manually to /etc/rcS.conf ?
  • jozeejozee April 2010
    yes, if you want it to be detected every time you boot. Other thing I want to check is whether "tazhw detect-usb" auto-loads mmc_block or not. Please check. I hope you are using or upgraded to 3.0.

    Another request would be to create a guide in http://doc.slitaz.org/en:guides:start and please write down your journey on installing, booting and using Slitaz from sd card. Many people many benefit from your guide.
  • monzmonz April 2010
    Hi jozee ... I would be happy to write a guide, but i don't have the faintest idea how to do it. Please explain how i can create one ... or maybe you can create the empty link and i'll fill it.
  • erniaernia April 2010
    login/register yourself here http://doc.slitaz.org/start , learn syntax here http://doc.slitaz.org/wiki:syntax?s[]=playground then practice here http://doc.slitaz.org/en:guides:playground.
  • monzmonz April 2010
    ok, thanks, i'll do it as soon as i have time.
  • monzmonz April 2010
