使用JTAG进行仿真，出现以下问题
* JLink Info: STM32F2xxx/STM32F4xxx: Can not attach to CPU. Trying connect under reset.
**JLink Warning: RESET (pin 15) high, but should be low. Please check target hardware.
***JLink Error: Supply voltage too low (1 Volt is required, Measured: 0.2 Volt).
Please check target power.
Error: Flash Download failed - Target DLL has been cancelled
