DDR Configuration Question

Hi,

 

We have designed a custom board based around the IMX6Q Sabre. A lot of the design is very similar, however we have gone for two 1GB RAM chips.

 

We have used DDR3 channels 0 and 3. when we try to calibrate the RAM using the stress tester it sees we have 2x1GB but fails as it tries to calibrate channels 1 and 2. If we only calibrate channel 0 it passes with no problems.

 

Is using channels 0 and 3 a valid configuration for the DDR or would I have to use channel 0 and 1?

If it is valid, how do I force the stress tester to ignore channels 1 and 2 during calibration?

 

Kind regards,

 

Kyle.
