LPDDR4 part selection for i.MX8 DualXPlus

kailas_kharse — Tue, 30 Jun 2020 18:25:47 GMT

Hello Team,

We going to design our custom board using iMXDualXPlus.

As there is Micron's LPDDR4 used on EVK board. We have plan to use JEDEC-compliant LPDDR4 8Gb (x16 x 2 channel ) provided by the customer for custom board?

Is there any known issue or risk if I use this part?

Please provide a solution to this topic as soon as possible because I require it's solution very urgent.

Which i.MX family DDR Tools I can use for i.Mx8DualXPlus?

What are the modifications we need to do in U-Boot OR Kernel for using different LPDDR4 Memory?

Regards,

Kailas Kharse

Hello Igor,

I have one more Use Case, I want to use Octal RAM which is interfaced via Flex SPI.

So is it possible to use Octal RAM instead of LPDDR4?

What are the changes need to use Octal RAM instead of LPDDR4 for I.Mx8DualxPlus Processor?

Thanks,
