DRA821U-Q1: DDR Test software/Firmware

Hi Max,

Can you edit your thread title to reflect the question you are asking instead of just the part number?

Hi Max,

For testing the DDR, you can use memtester. I've looped another expert in to answer your question about timing.

Hi Jared,

where can I get memtester? 

Thanks

Max

is there a way to find DDR signal quality by use this memtester, such as jitter, eye open etc.?

Hi Max,

memtester is a linux application that should come preinstalled on our default image.

can you provide LPDDR4 memory controller AC timing specification ?

We do not provide AC timing specification for the DDR subsystem.

Instead, we recommend you follow our LPDDR4 board design and layout guidelines (link below).
