NXP technical support Hello:
I have a question about SDRAM (W9864G6KH) to consult you. Firstly, there are two ways to initialize SDRAM. One is through call
BOARD_InitSEMC function is used to initialize SDRAM, but after I call BOARD_InitSEMC, I find that I cannot read and write SDRAM. I think there are some problems with my initial configuration. Could you please help me check? I modified it by referring to the DEMO instance evkmimxrt1170_semc_cm7 because my SDRAM is different from the development board.
Here is my initial configuration

This configuration should be correct。
I mean do you need to configure anything else besides initialization

In some other examples, you must enable "USE_SDRAM" definition and determine which part should re-locate to SDRAM.
