Hi, I'm new here.
I've started a project using the STM32F746 Discovery board and I've been messing around with the external SDRAM.
I copied the initialisation code from the FMC example, and used STM32CubeMX for the hardware initialisation. I am able to read and write from addresses 0xC0000000 to 0xC07FFFFC; i.e. any memory accesses at 0xC0800000 or above causes the default handler to be invoked. Has anyone else come across this problem?
