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?
