I tried simple code using Keil MDK5 for STM32F769 CPU. I've used Keil simulator and noticed that vector table is settled at 0 (ITCM RAM) with BOOT_ADDRx =0, directing CPU to start from 0. The question is how vector table was filled in RAM. If JTAG did it, what will happen when I don't have JTAG, ie in production ? If some code from flash did it, how CPU started from flash at the first place, if at least stack addr should be at 0 ?
I do not know this specific device, but often, the flash (or parts of it) are mapped to zero. So the CPU will fetch SP and PC from flash. But I guess an ST forum is the better place to ask those ST specific question.
