Release the Reset Button if you can establish a connection to target.<BR />The KL04 only support SWD, please don't select JTAG.</P><P></P><P>For the hardware:</P><P>The RESET_b pin should have a 100 nF capacitor close to the MCU for transient protection. An external 4.7 kΩ to 10 kΩ pullup is recommended.<BR />The NMI_b pin must not have any capacitance connected to it. An external 4.7 kΩ to 10 kΩ pullup is recommended.</P><P>SWD_DIO: an external 4.7 kΩ to 10 kΩ pullup is recommended.<BR />SWD_CLK: float or an external 4.7 kΩ to 10 kΩ pulldown is recommended.</P><P></P><P>Best Regards,</P><P>Robin</P><P style="min- padding: 0px;">&nbsp;</P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
