We are designing a board on i.MX 6SoloX with only a single DDR3 16bit memory chip K4B2G1646Q-BCK0.


1.    What I should do with the unused data, strobe, Chip select and other unused pins of i.MX? – Should I terminate/leave floating ?

2.    First bytes of data/strobe are routed on the top layer, without any via; but the next byte is routed in the internal layer with via’s . Is it ok?


Have attached my schematics. Please advise. Earliest reply would be highly helpful.
