eMMC not detected

Daniel MouritzenDaniel Mouritzen New Member Posts: 1
I have been using the UP board (4/32GB) for a few months now without problems, but since yesterday it has been unable to boot (goes straight to EFI shell).

The problem started after I had turned it on by accident and turned it off by holding the power button (during the UP splash screen). I booted from an Ubuntu live USB stick, but it could not find any other storage than the USB stick itself.

I have tried resetting the BIOS settings and unplugging the RTC battery, but it didn't help. After looking through the BIOS settings and noticed that under Chipset->South Bridge it says eMMC: Not Installed / Disabled, even though the SCC eMMC Support setting is set to ACPI mode (which I assume is the default).

Any ideas, or is the eMMC fried?

    Hi Daniel,
    Did you get a response on that?
    I am having similar issue after power disconnect.

    Hi @mkkr ,

    Could you, please, specify your sw and hw setup for UP board?
    BIOS verison, Linux distro and verison, etc.

    Cheers!

    Hi ccalde,
    BIOS: UP-CHT01 R0.T (UPC1BMOT)

    This is fresh up-board.
    When I was trying to install ubuntu it was showing errors for eMMC storage. Then after restart I cant even see eMMC available in South Bridge.

    Cheers,
    m.

    Hi @mkkr ,

    First, I would recommend you to update the BIOS for your UP board:
    https://downloads.up-community.org/download/up-board-uefi-bios-upc1dm11/

    After that, try to install the Ubuntu 16.04 and check there is no issues with your MMC any more.

    What kind of eMMC issue, anyway? Installation didn't find the your eMMC disk? Which Ubuntu version are you using?

    Cheers!

    I will try updating BIOS.
    To be more specific, when ubuntu 16.04 installer was copying files to eMMC disk, it started throwing errors saying that file could not be written.

    BIOS updated to UPC1DM11, but still cant see eMMC in south bridge.
    Additionally to that, BIOS is opening automatically after reboot

    Hi @mkkr,

    That could be a problem, yes.
    If you don't see your eMMC storage during the Ubuntu 16.04 installation, and even from the BIOS chipset configuration...

    The BIOS will be opened after reboot because you don't have any OS installed...

    Cheers!

    So should I try installing Ubuntu 16 if eMMC is not recognized in BIOS?
    What is the best way to move it forward?

    Anyone some help? My up board is useless now....

    Hi @mkkr ,

    You could try to install your Ubuntu 16 yes, but it will be complicate if BIOS doesn't recognizes the MMC...
    Anyway, let's try!

    Cheers!
