I am new to MCUXpresso IDE, I am working on frdm-mke15z, Intially my debugger was working but when I tried to configure some pin in input configuration I got below error.

Hi，

Can I ask which pin you set ?

Do you have a try to unlock kinetis by GUI flash tool in MCUXpresso,or use a jlink to unlock kinetis

Have a great day,

Thanks for reply.

I have set PE16, pin number 1.I tried GUI flash tool but it does not unlock kineties,

I don't have idea how to connect j-link externally(any soldering is required on board?).Please guide me for j-link.

Hi,

If your opensda's firmware is not jlink, you need an external jlink.

Please have a try .

I hope this help you .

Hi,

I have recur the issue. And this issue can be caused by SWD pins' wrong configuration.

And I have fixed it. The step as follows.

1st.Plug out the board.

2st.Press NMI button

3st.Plug in.

4st. Download a normal code.

I hope this will help you.

Have a great day,
