Mikrotik RB750r2 (hEX lite)
Reboot (SNAPSHOT, r4049-9412fc2) The snapshot build dated 28/04/2017 (Europe timezone)

I first did a boot up on TFTP with mikrotik-rb-nor-flash-16M-initramfs-kernel.bin and then downloaded the lede-ar71xx-mikrotik-rb-nor-flash-16M-squashfs-sysupgrade.bin via wget into cd /tmp

Then i did sysupgrade lede-ar71xx-mikrotik-rb-nor-flash-16M-squashfs-sysupgrade.bin however everything seems to be installed ok but got theses following errors?

root@LEDE:/tmp# sysupgrade lede-ar71xx-mikrotik-rb-nor-flash-16M-squashfs-sysupgrade.bin
