I want to use only 16bit of DDR3 data. I’ve followed all the instructions found here: https://rocketboards.org/foswiki/view/Projects/SoCKitGHRDWith16BitsExternalDDR3Memory
but it does not work for me. I cannot find any related topics about using just 16bit data out of HPS. I’ve stopped at memory calibration that is failing. I will be very glad if someone give me compiled preloader with only 16bit DDR3 data and u-boot if it possible.
