There are 2 memory sticks on the DDR controller 0 on the lx2160ardb development board, and there is no memory stick on the controller 1, but it cannot be started.log :

Two dual-rank DIMMs on one controller create great load on the DDR bus,  DDR speed needs to be reduced to support that load. Can you try to configure DDR interface to 1600MT/s  speed and try once again?

   first ,thank you! 

  When I slow down to 1600MT/S, ddr controller 0 can start normally when 1 or 2 DIMMs are inserted, but when 1 or 2 DIMMs are inserted into controller 1 can not bootup, the log is still the same as before. INFO: Execute firmware

Note, we don't provide support for all DIMM configurations for the LX2RDB.
Your last observation is expected, the current DDR init structure requires the controller 0 to be used if only one controller is used.
