Type struct pointer issue

Hello,
I'm stuck with hardfault handler.

When I try to execute read value from pointer address:

struct S2E_Packet { uint8_t module_type[3]; uint8_t fw_ver[3];
} __attribute__((packed)) S2E_Packet;

struct S2E_Packet s2e_packet;

AddressSrc=(uint32_t)&s2e_packet;
uint32_t test = *(uint32_t*)AddressSrc;
HAL_FLASH_Unlock();
HAL_FLASH_Program(TYPEPROGRAM_WORD, AddressDes, test);

program goes to hardfault handler.
No errors or warnings during compilation.

I have no idea.....
