    joximus got a reaction from goosnarrggh in Banana Pi M2 Ultra boot freezing trying to scan the EMMC   
    I tried quick test with dtbo file you provided and it works. This is the first time I have this board up and running. It would be great if you changes could somehow be included in future images provided for download.

    Update: Yes, a dtbo will work to reduce the bus from 8-bits to 1-bit and make the board bootable.
     
    This overlay does the trick for me:
    sun8i-r40-bananapi-m2-ultra-1bit-emmc.dtssun8i-r40-bananapi-m2-ultra-1bit-emmc.dtbo
     
    To test this for yourself: (You will need a working Linux machine to mount the SD card and make these changes.)
    Burn a copy of the current rolling release image onto a microSD card. Copy the dtbo file into the /boot/overlay-user/ subdirectory of the card. (You will need to use root/superuser access to have permission to modify the content of this directory on the SD card. Create that subdirectory if it doesn't already exist.) Edit the file /boot/armbianEnv.txt. (You will need to have root/superuser access to have permission to edit this file on the SD card.) If there's no line starting with "user_overlays=" in the file, then just add a new line to the end of the file: user_overlays= sun8i-r40-bananapi-m2-ultra-1bit-emmc Otherwise, if a line starting with "user_overlays=" is already present in the, then add a space to the end of that line's existing contents, and add sun8i-r40-bananapi-m2-ultra-1bit-emmc to the end of it.  
    Note: I linked both the dtbo binary, and the dts source code which created it. Only the dtbo file is needed for a quick test; if you wish you could compile the dts file from source code and prove that my work is reproducible.
