how dose the PC run to startup.s when the mcu reset

[xshen]

Hi，dear enginner：

  i want to know how the PC run to startup.s when mcu reset？

  The Definitive Guide to the ARM Cortex-M3 says address 0x00000000 is MSP‘，address 0x00000004 is ResetVector.

  But when I look at STM32F767, I find that 0x00000000 and 0x4 addresses are other instructions

Is there any reference material that can solve my confusion?

 Thanks.

Regards.

So what 32-bit words do you actually see when you inspect the memory?

What words at 0x08000000 ?​

This is the instructions in 0x0.

At 0x8000000 is vector table.

Shouldn't be instructions.

Suspect you don't have BOOT pins configured correctly.​
