After upgrade to armbian-next , it doesn't boot. Stop u-boot with space and boot manually:

# try to boot only from mmc
=> setenv bootcmd run mmc_boot
=> saveenv
Saving Environment to MMC...
Writing to MMC(0)... done

=> run mmc_boot
# this will fail, but will set some enviroment variables needed

=> setenv devtype mmc
=> setenv prefix /boot/
=> load ${devtype} 0 ${ramdisk_addr_r} ${prefix}uInitrd
4293052 bytes read in 676 ms (6.1 MiB/s)

=> load ${devtype} 0 ${kernel_addr_r} ${prefix}Image 
12957704 bytes read in 1386 ms (8.9 MiB/s)

=> load ${devtype} 0 ${fdt_addr_r} ${prefix}dtb/${fdtfile}
14505 bytes read in 397 ms (35.2 KiB/s)

=> booti ${kernel_addr_r} ${ramdisk_addr_r} ${fdt_addr_r}

# fix load addresses in /boot/boot.cmd
=> setenv fdt_addr ${fdt_addr_r}
=> setenv kernel_addr ${kernel_addr_r}
=> setenv ramdisk_addr ${ramdisk_addr_r}    
=> saveenv



fixed: boot.cmd
