I have a TWR-KV58220M board and i cant debug with J-link or PEmicro universal(via JTAG port).
I’ve tried to unlock it by using MCUExpresso Gui flash tool(Resurrect locked Kinetis Device) and i succeed.Afterwards i still got a trouble with connection to MKV58.
Those are the messages of “Resurrect Kinetis Device via J-Link”
When i look at the RESET_B pin of TWR-K58, i noticed that the RESET_B keep oscillating,i see a “square wave” in every 100ms.
I pulled RESET_B pin to low and tried to program with J-link and PE Micro Universal but no success.
Finally,I tried to connect TWR-K58 by using J-Link Commander.See the attachment for outputs.

How can i debug again this chip? What is the issue that i am facing?
Considering that you have PEmicro universal, please try to use the P&E recovery utility mentioned in Bricking and Recovering FRDM-KL25Z Boards: Reset, SWD Clock and Low Power.
Have you check the on-board OpenSDA debugger? It may also affect the KV58.
