After erasing the flash of a typical microcontroller with an ARM Cortex, I assume the flash contents to be all
What is the behavior of the microcontroller after reset, especially that of its processor, in this case?
The only things I am reasonably certain about are these: Upon reset, the inital PC and the initial SP are set to
I am unsure what happens next: Is there an exception because the stack pointer is unaligned? Does the processor fetch an instruction from memory address
0xffffffff? If the instruction is fetched, is it taken from the two bytes (I think it should be a Thumb instruction because the initial PC has the low bit set) at
0x00000000 or does the instruction fetch access wrap around the "System" section boundary from
