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
In particular, use the sheet, named "MX6 DRAM Bus Length Check".
Have a great day,
Yuri

thank you @Yuri Muhin for giving such guidance..
again i am facing the same issue .,a small doubt on this that i.mx6 solo board stress test already done successfully before 4 months ..
so i'm trying to do again on this board is that will give the same result or i have to go with a new board..!

Hello,
perhaps it makes sense to perform memory calibration again and use its
results in the initialization code.
