bootmenu is defined here: https://github.com/BPI-SINOVOIP/BPI-R64-bsp/blob/master/u-boot-mt/include/configs/mt7622_evb.h
official uboot is not booting, if compiled with gcc >=5.5 (needs to be comiled with e.g. gcc4.8 in ubuntu 14.4), gcc7/8 do not compile official uboot - as upstream supports mt7622/bpi-r64 including net and my repo also supports 32bit mode you can use a recent uboot now
