Well, when you said you installed armbian, you said booted from SD (Nov 20/2020)
So, you have 2 problems
And I guess you don't know that there is not a bios on ARM cpus (or rom on mb)
There are 4 steps in a boot
ROM in cpu, with VERY little memory, searchs for idbloader (fixed search order, specific locations)
idbloader enumerates and activates memory, so now enough memory for
uboot, which with an ALTERED search order looks for config files,
the first config found tells where kernel, initrd and dtb is located and loads them
1) your new uboot from armbian seems to fail loading from SD, if SD is correct for booting
2) because you see armbian logo, uboot is done, new kernel, initrd or dtb is faulty
disable or remove emmc, see if you can get a SD boot, if yes,,
re-enable emmc 2 seconds into reboot, check with lsblk to see if you got timing right
edit boot.txt and recompile or alter links in /boot to boot previous kernel, initrd, dtb (all this on emmc)
------------
every image I have seen (except for 1) will have a idbloader and uboot and maybe trust in 1st 16M(32768 sectors)
so the armbian image that you installed a year ago had these files,,,,
they are NOT in a filesystem, it is a raw read,,, that is why the 1st partition starts at 32768 or 62500(manjaro),,,
room for the boot files
