Dear Madam or Sir,

I have hardware problems with the K02FN128VLH10 unfortunately. If I connected the Segger J-link debugger, the application works and the signal Reset has logical 1 level. If I disconnected the debugger and toggle the DC power supply then the application stop running and the Reset pin generate pulses with 10 kHz period approximately. The empty microcontroller generates nothing. I am not sure if it is a hardware or software mistake.  I use the standard startup library from the Kinetis studio 2.0 and the developed application works with FRDM-K22F without problem. Really thank you in advance for your help. Your sincerely Michal Pokorny
