Hello,

 

 

   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

Hello,

  perhaps it makes sense to perform memory calibration again and use its 

results in the initialization code.

Yuri.
