I use ISE 14.7, 7 Series FPGA, MIG v1.9 and DDR3 memory model .
Memory controller works in 4:1 mode with BL=8. I try to write to the memory. And I see zeros on the memory data bus instead of the my first burst of 128 bits. The next writes are correct. What is the reason of this? Is my timing diagram right?
