+_Will we boot NuttX with Armbian or Yocto settings? `0x4400` `0000` or `0x4020` `0000`?_
+
+Armbian looks simpler, since it uses a plain Linux Kernel Image File `Image`. (Instead of Yocto's complicated Flat Image Tree)
+
+Hence we will overwrite Armbian's `armbi_root/boot/Image` by the NuttX Kernel Image.
