RH850/F1L MCU analysis anomaly indicating Error(E100000C)

hello all Renesas fans:

background:one RH850/F1L series MCU was sent to factory for defect analysis;

however,it indicated an error (E100000C) that aimed to the flash rom,showing the information as follow:

----------------

Disconnecting the tool

Error(E100000C): A serial programming connection is prohibited for this device. (Command: 00, Response: DC)

Operation failed.

--------------

HELP:

i wonder how to solve this problem.

(i guess the security module prevented the connect,or other factor to cause this problem?)

best regards!!!
