zynq HP interface burst can not set to 15?

I am using zynq 7015 HP interface to write data .  If my total data is an integer multiple of 128 bytes, such as 1280 bytes .  I set the burst length to 16. It works ok.

If my total data is an integer multiple of 120 bytes,such as 1200 bytes.  I set the burst length to 15.  It does not work ,it  transfers  only one burst to my DDR then  stop .

I can not get the reason.   I doubt it is related to burst length. Does it only be set to 2  ,4  ,8 , 16??

What's the HP interface? Is it a DDR3 interface?
