How execute In Application Programming code

Question

I write program with labview to read bin file of compiled STM32F103 code and send it to st micro with serial port Also in st micro i write program to get bin file from serial port My st micro code start address is 0x8000000 with 0x4000 size And my application code start address is 0x8004000 with 0x8000 size

I sucessfully write my received bin code in 0x8004000 but i don't know how to execute my code I try to use stm cube iap example method :

JumpAddress =*(__IO uint32_t*) (APPLICATION_ADDRESS +4);
JumpToApplication=(pFunction) JumpAddress;
__set_MSP(*(__IO uint32_t*)     APPLICATION_ADDRESS) ;
JumpToApplication() ;

but it don't work
