4G DDR3 memory references of IMX6 - android

[JHY]

Is there references of using 4G DDR3?

It is recognized in U-BOOT, but android kernel has errors.

So can I get the tested result about 4G DDR3 memory or information for compatibility?

Guys,

as Igor and Gary said, run the DDR test first i.MX6/7 DDR Stress Test Tool V2.52 . If the test will pass, try to run android with 1 or 2GB only. It looks like the memory chip is bad, bad signal routing or kernel is not compiled properly.

Hi,

The Boundary Devices Nitrogen6 MAX board is using 4GB of DDR3 with no issues. I suggest you look at the U-Boot cfg file and run the ddr stress test on your platform.

I also think that this can be caused by ddr errors.

Had you run ddr test, are you able to run successfully

android with just 2GB ?

Hi JHY,

at what speed your DDR is running now?

Hi Michal,

This is Andy cho. JHY is our colleague.

Below is log file of Memory. Would you please check what is problem ?
