Abstract
A storage system including: a storage device; a diagnosis circuit that generates a test pattern, transmits the test pattern to the storage device, receives result data corresponding to the test pattern from the storage device, and tests whether the storage device normally operates by comparing the test pattern with the result data; and a debugging port that is connected to the diagnosis circuit, receives auxiliary power from an external device, supplies the auxiliary power to the diagnosis circuit, and transmits data in the storage device to the external device.
Claims20
A storage system comprising:
- a storage device comprising a data i/o port that receives power from a host of the storage system;
- a diagnosis circuit that generates a test pattern, transmits the test pattern to the storage device, receives result data corresponding to the test pattern from the storage device, and tests whether the storage device normally operates by comparing the test pattern with the result data;
- and
- a debugging port that is connected to the diagnosis circuit, receives auxiliary power from an external device external to the host, supplies the auxiliary power to the diagnosis circuit, and transmits data in the storage device to the external device.
An operation method of a storage system, comprising:
- connecting auxiliary power to a debugging port of a storage system including a storage device in which driving data about a vehicle and its drivers are stored, wherein auxiliary power is provided by an external auxiliary power source different from a main power source for the storage system;
- determining whether a diagnosis circuit, which tests whether the storage device normally operates as the auxiliary power is input, normally operates by using a built-in self-test (BIST) circuit in the diagnosis circuit;
- determining whether the storage device normally operates when the diagnosis circuit normally operates;
- and
- reading the driving data through the debugging port when the storage device normally operates.
A computing system comprising:
- an external device;
- and
- a storage system that includes a storage device in which driving data about a vehicle and its drivers are stored, and a diagnosis circuit that generates a test pattern, transmits the test pattern to the storage device, receives result data corresponding to the test pattern from the storage device, and determines whether the storage device normally operates by comparing the test pattern with the result data,
- wherein the storage device receives main power from a main power source different from the external device,
- wherein the diagnosis circuit generates the test pattern in response to receiving auxiliary power from the external device, and
- wherein the storage system transmits the driving data to the external device through a side band interface (SBI) when the storage device is normally operating.
