Abstract: A technique for operating a processing device is disclosed. The method includes irreversibly activating a testing mode switch of the processing device; in response to the activating, entering a testing mode in which normal operation of the processing device is disabled; receiving software for the processing device in the testing mode; based on whether the software is verified as testing mode-signed software, executing or not executing the software.
