Hi all,

 

We are using custom board K70 MCU. Problem in DDR2 write and read in some boards. I am using memory test program to test the DDR2. Configurations of DDR2 remains same as K70 Tower kit. I am shifting bit '1' 8 times at location 0x80000000 for databus test. While reading it 11111111 is not written properly, instead 00000000 is written. I have tested in various address also. How to solve this problem?

 

We are using DDR2 MT47H64M16HR-3IT:H

 

Regards,

Kayathri
