+User program conditions
+The user application to be loaded into the Flash memory using IAP should be built with
+these configuration settings:
+1. Set the program load address at 0x08003000, using your toolchain linker file
+2. Relocate the vector table at address 0x08003000, using the
+"NVIC_SetVectorTable"function or the VECT_TAB_OFFSET definition inside the
+"system_stm32f10x.c"
+
+can be found here system_stm32f4xx.c
