I was trying to backup a Zimaboard computer and G4L booted fine but it just didn't see the onboard eMMC storage. I'm guessing the kernel modules have not been compiled?

Is it possible to add support for eMMC storage?

    Have updated bz6x7.9 kernel to add option
    CONFIG_PHY_INTEL_LGM_EMMC=y
    and rebuilt that kernel.

    Looked thru menuconfig, but couldn't find option in make menuconfig, so just activated it in .config
    Did make, and updated the above files, so both the syslinux iso and the grub4dos image files.

    Don't have the EMMC so having tested.
    Currently in Nevada taking care of mom from hospital, so remotely accessing machines in Guam.
    Didn't update the bz6x8 kernel, since it just came out of rc?

    I tried the alpha you built and it didn't see the eMMC storage.
    Here's the output of lsmod taken from a working debian install:

    The modules needed seem to be sdhci and sdhci_pci.

    Also, the inclusion of lsblk would be useful, but perhaps I should open a new feature request for this.

    But don't spend too much time on this, take care of your family!

    Made a new alpha30 and new g4lefi.img
    had added the eMMC set to y, and had hoped the make oldconfig would have set any required options, but it appears it didn't. So, set the MMC-y, and then make oldconfig prompted for a number of other things.
    Also, added lsblk which just required the program since all linked libraries were already thers.

    Need to download new files.

    Might need < # CONFIG_MMC_SDHCI is not set
    to be set on, but it didn't prompt for Y on it?, but if it doesn't work, can set it, and rebuild kernel and make a version 31.

    went ahead and make a new 31alpha and new g4lefi that have that added.

    I tried alpha31 and it worked! (at least for backing up, haven't tried restoring but I see no reason why it shouldn't work) Found lsblk too, hope it didn't bloat the iso too much because it's useful having it.

    Thank you!

    The difference in kernel size between bz6x7.8 and the added 6.7.9 is just about 93K of the 12M total size in difference. So not much there, and the lsblk was a small addition to ramdisk.lzma size. Just need to see what lines were change in config file, and add them to the bz6x8 .config. Generally keep the latest stable kernel, and the rc kernel, but 6.8 just went to released status. Usually wait for next rc to come out before changing default. Glad it works.
