DDR3 Memory bus IMX6DL

Hi all,

I would like to use an IMX6 Dual Lite with less than 4 DDR3 chips, so in 16 or 32 bit DDR3 mode

Somebody can tell if this is possible ?

Thanks.

Thanks for this answer.

Have you any datasheet or application note for bus use in 16 or 32 bit ?

I find documentation only for 1x64 bit (DDR3) or 2x32 bit (LP-DDR2).

Regards,

Sébastien

size is defined by MMDCx_MDCTL[DSIZ] DDR data bus size. Also one can check presentation on
