我用了三根线分别接到swdio swdclk  gnd  但是一直有一个这样的错误
* JLink Info: STM32F1xxx: 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: 0.8 Volt).
Please check target power.

请问如何解决???
