Hi all

 

My customer plan to use DDR3 and want to divide DDR memory by function.

For example, one is for boot and the other is for image buffering.

 

SABRE-SDP is following connection. (Figure 1)

    

 

My customer wanto to use following connection. (Figure 2)

 

However, according to the Table 45-13 of  IMX6SDLRM Rev. 2, 04/2015, MMDC support 2 channels only when user use LPDDR2.

 

Q1

Can we use like Figure 2 ?

 

Q2

If Q1 is yes, can we divide DDR memory by function ?

For example, one is for boot and the other is for image buffering.
