HAL_FMC_MspInit() generated by F4 CubeMX initializes all FMC related pins as
GPIO_InitStruct.Speed = GPIO_SPEED_LOW; SDRAM is driven at max 84MHz frequency (STM32F429). I know that SPEED_LOW is only a slew rate (~a lower current generator at output driver), and traces to SDRAM are short and low capacitance, so they may be toggled quickly even with low driving power. Isn't it a problem? (It's a newly designed board; I haven't tested it yet) #fmc-gpio-speed-cubemx
