app cannot execute after bootloader startup and jump to app address.

STM32f103 uses internal clock and run bootloader correctly. Bootloader can jump to 0x8008000 where app is in.  In keil debug, I can see the break point is in main() entrance . But it can not execute continuously. So I want to know it is clock not run correctly? 

I used stm303/207 and they can run well. The only difference is that they use external oscillator. Thanks.

Make sure you have code in, and called by, SystemInit() that correctly sets up the Vector Table (SCB->VTOR), and is coded sufficiently robustly that it is immune to entry conditions, than just reset conditions.

If the boot loader has external clock and PLL functioning, why tear that down, to waste time bringing it up again, etc.The code in system_stm32fxxx.c is simple and general purpose, you will need to clean and tailor it to meet your own needs.Use the debugger to understand where it is stuck, and that you have a functional Hard Fault handler in both bootloader and app, so when it dumps out there, you have some diagnostic output to work with.
