KW36 jlink debug error

hello dear NXP engineer.

i am using jlink to debug with kw36 ble. the board is layout by our company. it is not the demo board,

i extend the jlink pin from the testpoint and connect with a ARM simulator purchase from internet, the version is arm11. detail info refer to attached pic.

firstly it can debug and run into breakpoint normally. after several times erase all operation. it no longer work normal now, pop up connect failure. i try to power on/off and plug in/out. the malfunction still exist.

try to unlock kinetis with jlink command 7.66 operation not ok.

why after i done the erase the jlink is not work normal. would you please give some idea and how to restore jlink debug.
