dont worry about this if u use openwrt firmware !!! its normal
- its just like information noize
- this uboot not fully configured and cant erase emmc - its same ok
both of them dont make any problem for openwrt workability
PS: may be next time i can clean it
PS: store init 3 - its just amlogic specific - u can forget about this - for example next mainline uboots dont have this commands same as many other specific from am-logic at all
