iMX6DL 2DDR configration

[Anonymous]

Hi, community.

We are going to use 2 DDR with i.MX6DualLite.

At that time, what should we do for upper 32 bits HW pins?
Is that ok to leave unconnected?

DATA32~63
SDQ4~7 P/N
DQM4~7
SDCLK_1 P/N

Thank you.

Hi, Weidong.

Oh, that's good.
We can just design one board pattern and try 2 types of i.MX.

Thank you so much!!

Hi, weidong

Thank you for your reply.

I see.

Then, Power configuration (VDDARMxx_xx Power Connections) is same between i.MX6 DualLite & i.MX6 Solo.
So if we use only 2 DDR, we can use completly same board layout pattern for DualLite & Solo.

Is my understanding correct?

Thanks in advance.
