How do I find the base address of "NOR Flash/PSRAM/SRAM/ROM/LCD 1" on a STM32H743?

With the STM32F427, the generated code included a couple of different #defines which mapped to the address to which I needed to write: e.g. #define FMC_BANK3_BASE ((uint32_t)(0x60000000 | 0x08000000)) Where can I find similar #defines in a CubeMX…

Can the STM32H743's FMC drive a 16-bit 8080 bus faster than 1.6MHz when clocked at 480MHz?

I'm using the FMC of the STM32H743 to drive a 16-bit 8080-bus LCD controller. I've tried using DMA, MDMA and a CPU-loop to transfer data to the 8080-bus, via the FMC. The transfer frequency does not depend on whether DMA, MDMA or CPU-loop is used. …
