MK64FN1M0VLQ12 protected chip and timeout for connection

Hi

I have a problem with the MK64FN1M0VLQ12 on custom boards. I tried programming with two versions of micro PE (USB Multilink Universal and USB Multilink Universal FX) and Segger J-Link from KWIK-STIK, the result is protected chip or timeout for the connection.

I found several forum posts related to the secure Kinetis system, such as unlock command and erase_all script on J-Link, Kinetis_Recovery_Utility.exe from PEMicro. Try several, with no success.

I can not find the cause of this problem. I tested three boards and replaced five microcontrollers without success.
Following is the response of the J-Link commands on the three boards and the schematic of the microcontroller part.

I need help to find the cause this problem.

Thank
