摘要: Methods, machine-readable tangible storage media, and data processing systems that enable a debug host device to acquire memory dump information from a debug target device after the target device suffers an unrecoverable system malfunction are disclosed. In one embodiment, data in the volatile memory on a debug target device is accessed via a hardware integrated debug framework, which is also used to access data on a nonvolatile electronically erasable semiconductor memory of a debug target device, and one or more registers of one or more processors on a debug target device, and a core dump is created on the debug host device.

摘要: A method and an apparatus for establishing an operating environment by certifying a code image received from a host over a communication link are described. The code image may be digitally signed through a central authority server. Certification of the code image may be determined by a fingerprint embedded within a secure storage area such as a ROM (read only memory) of the portable device based on a public key certification process. A certified code image may be assigned a hash signature to be stored in a storage of the portable device. An operating environment of the portable device may be established after executing the certified code.
