Can't run metarouter on hap ac/hap ac lite

Every time I create a mr run start , the state is forever booting.
This is the infomation on Manual Page…

Currently MetaRouter can be used on

  • RB400, RB700 series except models with SPI flash, RB900 series, RB2011 boards
  • Listed PPC boards: RB1000, RB1100, RB1100AH and RB800.

yep, confirmed…

That “except models with SPI flash” clause also applies to RB900 series (check it out here), and both “hAP ac” and “hAP ac lite” are RB900 series models with SPI flash.
