I set the FMC Base Address as 0x6c00007ebut this value is changed to 0x7800007Eand lcd doesn't show anything. I changed this value to this.It works properly.and I changed the value as 0x60000000,CubeMX is automatically generated correctly.
Oh, thank you. In fact, when we set the NEx and lcd Register selection (I am using A6), the FMC base address can be automatically generated by CubeMX, so we don't need to set the value.
