FMC SDRAM Configuration

I am unable to configure FMC with SDRAM in latest STM32CubeIDE 1.6.1.

Regardless of what I chose in the Mode section. Can someone guide me, what settings I have to perform?

Hello,

As stated in the datasheet , the SDRAM1 is only available for H725A.. and H725I.. ( 179 and 176 pin packages )

SDRAM2 being available only for H725I.K ( UFBGA176 package )

Please refer to DS13311 Rev 2 / table "Table 2. STM32H725xE/G features and peripheral counts"
