Hi,

I am using Micron MTK512M16HA-125 DDR3-1600 DRAM ( 1x 4 gigabyte) on my custom board .When  I  try settings which shown below  with 64 bit bus width ,   DDR stress test program ( NXP DDR Stress Tool v2.92 )  fails calibration and card's cpu freezes. 

Is there any wrong configuration on my settings ?

Thanks for help ,

Hello,

 

  i.MX6 memory frequency is about 533 MHz, therefore it makes sense to try 

using DDR3-1066 specs. You may try tRC = 52.5 ns; tRAS=37.5 ns.

  Also, please check if Your PCB design satisfies recommendations of the 

HW_Design_Checking_List_for_i.MX6DQP6DQ6SDL:

HW_Design_Checking_List_for_i.MX6DQP6DQ6SDL 

https://community.nxp.com/servlet/JiveServlet/downloadBody/93819-102-17-270033/HW_Design_Checking_Li... 

  In particular use the sheet, named "MX6 DRAM Bus Length Check".

 

Have a great day,

Yuri
