I have figured out.
I used my own BSP (stm32f7).
It happend only with SDRAM.
The example worked correctly with internal flash.
Also i wrote a small inline asm functions for atomic
They both worked correctly with internal RAM.
They worked correctly in bsp_hook, bsp_start, but they did not work in Init
function(I recived _ARMV7M_Exception_default) with SDRAM.
I think i have problem with MPU configuration
