I am referring to the following Sabre SD DDR RAM schematic and I need to know how to configure the pin map of the processor and RAM. (The order of the DRAM_D[0 to 63] with DQ[0 to 15] )
MT41K128M16JT RAM has used in Sabre SD board and the pins have connected as follows.
DRAM_D0 >> DQ0
DRAM_D1 >> DQ3
DRAM_D2 >> DQ6
DRAM_D3 >> DQ4
How the above bit pattern select according to each RAM. Do we have any method to know which DQ pin will connect with DRAM pin ?
