IMX8M nano lpddr4

[link]

Hi all:

     In our imx8mn+LPDDR4 board, the copy rate of DDR tested with sysbench is 2660 MiB/s.
but in imx8mnEVK(lpddr4) ,the copy rate is 3200 MiB/s.Our board are much slower than imx8mnEVK boards.

    We used MSCALE_DDR_Tool to execute the DDR training, code generation and stress test.There is no problem.
    We want to know what causes this problem?

The CPU frequency does not increase because the PMIC configuration is abnormal

How the LPDDR4 you are using, with the 2660 MiB/s?
