[motorinnv94]

Dear NXP,

I am hardware engineer. Now i am working on development SoM with using i.MX8QuadXPlus.

I am using 2-die LPDDR4 memory. What i need to do with extra i.MX8QuadXPlus pins (CS1_A, CS1_B, CKE1_A, CKE1_B). I need to left this pins floating or use resistors to pull up or pull down or connect to LPDDR4 NC pins?

Hello Nickolay Motorin,

The i.MX8QXP documentation is still nor publicly released so I would need to ask you to please contact your NXP Distributor or FAE for more information on what documents are available. The i.MX documentation at the time of a processor’s release include recommendation for unused pins and interfaces.

My apologies for the inconvenience.

Regards,
