Hello I use
https://download.fedoraproject.org/pub/fedora/linux/releases/29/Server/ar...
image which I unxzip and use dd for write it to new SD card.
Do you then separately write out the U-Boot firmware? If not you
should use arm-image-installer with the appropriate device target (I
think it should be Lamobo_R1) to setup the firmware for the device.
