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?
