    No, mmcblk0 is almost certainly your sdcard, just from the partitions on it

    It's really common for android to have boot0, boot1, rpmb on the emmc, that is likely where it is (blk2)

    If you have checked your evb.dtb by turning it into a dts, check dwmmc@ff500000, and  @ff520000

    for  bus-width = < 0x04 >;  or 0x08 and the  aliases {  ,, then you will know for sure

    You do know this will wipe out your android?  Before you do that, it would be good to

    extract the android dtb because it is sometimes hard to get the right image for your hardware,

    there are so many slightly different images

    wdtz,
    thanks for your reply. I didn't check the dtb, I've simply selected the dtb selected by another user with the same device (A5X MAX) . So it seems that I'm using a wrong dtb and that I have to
    - get the right dtm by extracting it from android.
    - put a reference to it in /extlinux/extlinux.conf

    Am I correct?

  2. As a newcomer, I have to start by thanking balbes150 for his excellent work.

    I'm running my first tests with Armbian With following environment:
    - box:   A5XMax with 4GB RAM 32GB disk
    - image: Armbian_5.68_Rk3328-tv_Ubuntu_bionic_default_4.4.154_desktop_20190110.img
    - FDT:   /dtb/rockchip/rk3328-evb.dtb

    Armbian boots without problems from microSD card (Sandisk Ultra 16 GB) and runs fine.

    When I try eMMC installation and run /boot/create-mbr-linux.sh, I get following output:
     

    Start script create MBR and filesystem
    /dev/mmcblk0p1 /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro 0 0
    /dev/mmcblk1
    Start backup u-boot default
    dd: failed to open '/dev/mmcblk1': No such file or directory
    Start create MBR and partittion
    Error: Could not stat device /dev/mmcblk1 - No such file or directory.
    Error: Could not stat device /dev/mmcblk1 - No such file or directory.
    Error: Could not stat device /dev/mmcblk1 - No such file or directory.
    Start restore u-boot
    8192+0 records in
    8192+0 records out
    4194304 bytes (4.2 MB, 4.0 MiB) copied, 0.195129 s, 21.5 MB/s
    Done

    It seems that the script selects /dev/mmcblk1 as DEV_EMMC, but /dev/mmcblk1 does not exists, while /dev/mmcblk0 is there.

    This is the relevant section of /proc/mounts, that is used by the script for evaluating DEV_EMMC value.
     

    /dev/mmcblk0p2 / ext4 rw,noatime,nodiratime,errors=remount-ro,commit=600 0 0
    /dev/mmcblk0p1 /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro 0 0
    /dev/mmcblk0p2 /var/log.hdd ext4 rw,noatime,nodiratime,errors=remount-ro,commit=600 0 0
    

    This is the output of ls -lh /dev/mmc* 

    brw-rw---- 1 root disk 179,   0 Jan 10 09:04 /dev/mmcblk0
    brw-rw---- 1 root disk 179,   1 Jan 10 09:04 /dev/mmcblk0p1
    brw-rw---- 1 root disk 179,   2 Jan 10 09:04 /dev/mmcblk0p2
    -rw-r--r-- 1 root root      12M Jan 10 22:19 /dev/mmcblk1
    brw-rw---- 1 root disk 179,  32 Jan 10 09:04 /dev/mmcblk2
    brw-rw---- 1 root disk 179,  64 Jan 10 09:04 /dev/mmcblk2boot0
    brw-rw---- 1 root disk 179,  96 Jan 10 09:04 /dev/mmcblk2boot1
    brw-rw---- 1 root disk 179, 128 Jan 10 09:04 /dev/mmcblk2rpmb

    I'm tempted to modify create-mbr-linux.sh and to force
    DEV_EMMC=/dev/mmcblk0

    and to do a similar modification in /root/install.sh, where there is the same mismatch, but I prefer to ask for your suggestion before taking and risk.
