Why is HAL_NVIC_SystemReset() not working for MP1?

[nrg6]

After the execution of the function HAL_NVIC_SystemReset() the CM4 did not jump to the Reset_Handler in the startup file. It ends up in "Break at address "0xa05f000c" with no debug information available, or outside of program code."

I know that it's working for other STM32F4.

Any ideas?
