Sometimes it depends on the boot mode. You can locate the NOR flash memory = at 0x00000 or 0xfff00000 (via bootstrap pins) and in the latter case the = vector table is at 0xfff00000 (at least the reset vector)! > Also there is no SDRAM at 0xfff00000, right? Yes, but (maybe) flash. > Requesting SDRAM there will fail every time for a good reason.
