I replaced the original SDRAM with W9812G6KH. What should I do when I meet this problem.

Hello
I hope you are well.

This issue might be related to the SDRAM parameters. I suggest you use SEMC example as reference to test your SDRAM. In that example, you will modify the parameters from your SDRAM datasheet. 

Best regards,
