AM6548: AM6548 EMIF tool

Part Number: AM6548

Hi Ti ,

We want to lower DDR frequency within AM6548 for test.

But when we adjust the frequency from 800 to 666 for example,  the EMIF tool cannot export dtsi file and pop up error message.

Here we modify the frequency to 666MHz and Data Rate to 1332 Mt/s.

If AM6548 only support DDR4 at 800MHz?

Thanks.

Eric

    Try just modifying the Memory Frequency.  The Data Rate refers to the max data rate of the memory, and should not change with operating frequency.

    And there may be other parameters on the following tabs that need to change.  Please refer to the DDR4 datasheet speed bin tables and AC timing tables for your operating speed

    Regards,
