Reset vectors remapping in STR7

Nivelinn Pantev

Hi to All,

I am trying to do the following: to copy ARM reset vectors (64 bytes) from internal flash to internal RAM, then to set boot configuration of CPU so 0x00000000 to reference 0x20000000 (internal RAM), so in this way I have reset vectors in RAM.

Well, Application starts, but and some point it stacks and I observe these 64 bytes changed.

Linker is instructed (I tried with Keil and ARM tools – same result) to use internal RAM with 64 bytes offset from: 0x20000040.

What might write in this area?

Thank you in advance,
Nivelinn
