calibration of ddr4 interface on 10AX066H4F34E3SG

Hello sir,

I'm Adzim. Thanks for using Intel Community.

There are some possible causes that produce the calibration error.

But I need ask some questions first.

Have you tested all the 3 devices individually?

I mean connect one device to the project and tests it.

Repeat with another device.

Or the issue only happens when you trying to use 3 device all together?

Because of you are going to use multiple device, please check the following:

Do you enable the EMIF Debug Toolkit option?

Do you enable the address mirroring option?

There is a known issue when using the 10AX066 device.

You have to make sure that the reset is held for about 200ms after the initialization process.

Is that possible to know the calibration error?

Thanks,

Adzim
