Discovery F7 BSP Drivers for display, stm32CubeMx, SW4
I’m headed down the same path. (Brilliant minds think alike! 
)
Have you looked at stm32f7xx_hal_conf.h? It seems like ST uses that to enable various HAL modules. MX will uncomment some of the defines near the beginning of this file but not all required for the BSP. I found I had to enable HAL_SDRAM_MODULE_ENABLED manually.HAL_StatusTypeDef is pretty fundamental and I cannot imagine why that’s coming up undefined.
I also ran into the problem with the UART. I included some logging file and I suspect it might support logging to a UART. I resolved that issue by configuring UART6 in MX.
Otherwise I’ve just been copying files to my project directory as needed. I’ve been wondering if it is better to do that or add he BSP files as external references. For this project thsy should not require modification.
