Hi guys,
I have a strange problem about STM32F429-DISCO. I have used this board in a couple of weeks. I have run every hardware blocks successfully including SDRAM. Everything look fine to the right now! I want to execute code from the external SDRAM. But it always fails and throw the "Hardware Fault" exception. Why? I try some SDRAM initialization combinitation different from the orginal that is suggested by STMicro. Unfortunately I didn't achieve it. Do you have any idea or suggestions.
