i try to develop a board using MCF5208 and ISSI IS42S16400(64M-bit,16bit width SDRAM).
I found a very strange issue :
when i try to change a data in the SDR ,another address will changes accordingly.
The address is the current address + 256
When I write a 0x0002 to 0x40000000, the data at 0x40000200 will change to 0x0002
my schmatics follows the illustration on Page 317 Figure 8-2 of MCF5208RM.
Your help will be highly appriecated .
Thanks a lot
