S32K3 MCU debug port secure with good ADKP

[Shaun666]

Hello

I have an ECU with static ADKP for debug port, and I have previously connected to the ECU using the Lauterbach with the ADKP. but today, I try to debug  the ECU with same to previous script ，the Lauterbach feedback debug port secure. Do you have the same situation? I only have Lauterbach ，how can I stable connect to JTAG？

attached is the script of Lauterbach.

I am afraid I cannot provide solution without deeper knowledge what actually happened. Could you share some screenshots or logs?

since I can't connect the MCU, so I have a screenshot only this. Do you have any method remove the ADKP if I connected the MCU with JTAG?

I am afraid on this device there is no mechanism how to unsecure the device in such cases when it is not known what actually happened.
