getClientFrameBuffer()generated data error

[F1412.1]

Hi

I had a probelm when I ported the program

I use FSMC(8080) ,and I reffered to the stm32f412-discovoery example

Everything else is nomal except the getClientFrameBuffer()'s buffer

this is my UI in the designer:

so if the data which will load to the Gram is correct ,it should be 0x00000​(most),

but now it is who can help me
