I have a board designed with a KL15Z128. My problem is that I can program the controller only sporadically and debug. I have find out that when the programmierrung failed, the reset line toggeld. If programming was successful, the reset line is high.
I also have a crosstalk of the clock line to the reset line
If a program is in the controller I have no problems to debug.
I use the J-Link debugger.
Here's what I've already tried:
Reset line pulled up.
SWDIOLeitung pulled up.
Capacitor between Reset and GND.
Unfortunately, all without success.
Does anyone have any idea what this problem is?
