I test new sysupgrade with several Mikrotik boards (RB912 in particular) and despite some ambiguous it works like a charm. Most notable is selection of proper image from two's available: "nand-64m" or "nand-large". You could find related discussion here [1]. In short, you should use 'nand-64m' image for NAND with 512-bytes pages, and 'nand-large' for NAND with 2048-bytes pages. All RB912 boards which I saw are equipped with NAND IC with 2048-bytes pages, so the common choise for this boards is 'nand-large-squashfs-sysupgrade.bin' image. 1.
