Peng,
I have found one more piece that is missing from the lpddr4 initialization. We don't have a structure, or place to change the DDR PHY DQ lane to memory mapping registers. Our board requires this and was failing until I patched it in.
According to the code generated from DDR tool this should happen after /* step7 [0]--1: disable quasi-dynamic programming */
Actually, the DQ lane config is part of ddrphy config. The DDR PHY DQ lane config will be put in the ddrphy_cfg array in latest DDR tool.
Okay, I can adjust my scripts to make this change. Any ETA as to when the new DDR tool will be available?
Thanks, Jon
