Hi guys,

My custom board which is based on T1024, has DDR3L module MT4KTF25664HZ-1G9P1 (CL13, 1.35V, CLK:1.07NS/1866MT/S).  Before we were using MT4KTF25664HZ-1G6E1 (CL11, 1600MT/s) in our design and working properly  with below register configuration.

  

{1,  833,  4, 4,6, 0x06060607, 0x07080800},   

     {1,  833,  0, 4,6, 0x06060607, 0x07080800},  

     {1,  1350, 4, 4,7, 0x07070708, 0x08080800},   

     {1,  1350, 0, 4,7, 0x07070708, 0x08080800},  

     {1,  1066, 4, 4,7, 0x06060708, 0x07080800},   

     {1,  1066, 0, 4,7, 0x06060708, 0x07080800},

     {1,  1666, 4, 4,7, 0x06070809, 0x080A0A00},   

     {1,  1666, 0, 4,7, 0x06070809, 0x080A0A00},

 

After chaging the DDR module to MT4KTF25664HZ-1G9P1 , most of the times  UBOOT stopping at DDR..

 

 

Kindly help us in changes to be done in above registers to work with CL13 DDR module..

 

 

Below attached the DDR module datasheet..

 

Thyank you..
