It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1
Fig. 1 is a flowchart of a chip diagnosis method according to an embodiment of the present invention, where the method may be applied to the case of chip diagnosis, and the method may be performed by a chip diagnosis device according to an embodiment of the present invention, where the device may be implemented in software and/or hardware, as shown in fig. 1, and the method specifically includes the following steps:
s101, receiving a diagnosis signal.
In this embodiment, the Chip diagnosis method is applied to a Chip, which may specifically be an SOC (System on Chip) Chip, and the Chip includes: an MCU (Micro Controller Uint, micro control unit) core and an MPU (Micro Processor Uint, micro processing unit) core, the chip diagnosis method being executed by the MCU core.
In this embodiment, the diagnostic signal may be a signal transmitted from an external diagnostic source to diagnose a chip failure. By way of example, external diagnostic sources may include: OTA (Over-The-Air) upgrade module, remote diagnosis module and vehicle external diagnosis instrument, wherein, OTA upgrade module and remote diagnosis module can send The diagnosis signal through The mode of high in The clouds communication, and vehicle external diagnosis instrument can be connected with The automobile end through equipment such as computer and then send The diagnosis signal.
Specifically, the MCU core receives diagnostic signals transmitted from an external diagnostic source. In the actual operation process, the received diagnosis signals are in a first-come first-served principle so as to realize the coordinated control of each diagnosis system and ensure that the diagnosis resources of the controller are used as required.
S102, determining target data according to the diagnosis signals.
The target data may be data for determining a diagnosis signal, specifically, what portion or function of the chip is to be diagnosed. In actual operation, the target data may be in the form of binary data. For example, if the target data is 0001, it may represent that the diagnostic signal requires diagnosing the chip part 1; if the target data is 0010, it may represent that the diagnostic signal requires diagnosis of the function 2 of the chip, or the like.
Specifically, after receiving a diagnostic signal sent from an external diagnostic source, the MCU core determines target data according to the diagnostic signal.
And S103, if the MPU core is in an idle state, transmitting the target data to the MPU core so that the MPU core can diagnose the chip according to the target data.
The idle state may be a state in which the MPU core is idle, i.e., not performing chip diagnosis.
Specifically, if the MPU core is in an idle state, the MCU core transmits the target data to the MPU core, so that the MPU core can diagnose the chip according to the target data.
In the actual operation, the MCU core may transmit the target data to the MPU core by means of IPC (Inter-Process Communication ) communication. When the MPU core is in an idle state and can execute a chip diagnosis function, the MCU core transmits target data to the MPU core, and the state of the MPU core can be updated to a non-idle state.
Otherwise, if the MPU core is in a non-idle state, a prompt message is generated.
In the embodiment of the invention, the MCU core receives the diagnosis signal, and determines the target data according to the diagnosis signal, and if the MPU core is in an idle state, the MCU core sends the target data to the MPU core so as to enable the MPU core to realize the diagnosis of the chip according to the target data. Through the technical scheme of the invention, the SOC chip CAN be compatible with the function of diagnosis through the CAN bus, and the research, development and production costs are reduced.
Optionally, the diagnostic signal is CAN protocol data.
In this embodiment, the diagnostic signal is in the form of data of the CAN protocol.
Determining target data from the diagnostic signal, comprising:
and carrying out decryption operation on the CAN protocol data to obtain decrypted CAN protocol data.
In the actual operation process, in order to ensure the communication safety, the diagnostic signal sent by the external diagnostic source to the MCU core is generally data in an encryption mode, and after the MCU core receives the diagnostic signal, the diagnostic signal needs to be decrypted to obtain the decrypted diagnostic signal in the form of CAN protocol data. The specific decryption method and process are not limited in this embodiment.
And extracting target data from the decrypted CAN protocol data.
Specifically, after the MCU checks the diagnosis signal to decrypt, the decrypted CAN protocol data CAN include a check code, a file header, target data and other data. The MCU core extracts useful target data from the decrypted CAN protocol data.
Optionally, the diagnostic signal carries identification information of the diagnostic source.
In this embodiment, the identification information may be used to identify from which external diagnostic source the diagnostic signal specifically originates, and different external diagnostic sources may set different identification information, where the identification information may be represented by canid. Illustratively, the identification information canid of the diagnostic signal from the OTA upgrade module may be 001, the identification information canid of the diagnostic signal from the remote diagnostic module may be 002, and the identification information canid of the diagnostic signal from the vehicle external diagnostic apparatus may be 003.
If the MPU core is in the idle state, the method further comprises the steps of:
and receiving the diagnosis result sent by the MPU core.
The diagnosis result may be a result fed back after the SOC chip is checked by the MPU to perform diagnosis. The diagnosis result may be, for example, that the component a has failed or that no failure has been diagnosed.
Specifically, the MPU core generates a diagnosis result after diagnosing the chip according to the target data and sends the diagnosis result to the MCU core, and the MCU core receives the diagnosis result sent by the MPU core.
And sending the diagnosis result to a target diagnosis source corresponding to the identification information.
It should be explained that the target diagnostic source may be an external diagnostic source corresponding to the identification information carried by the diagnostic signal.
Specifically, after receiving the diagnosis result, the MCU core determines a target diagnosis source according to the identification information carried by the diagnosis signal, and then sends the diagnosis result to the target diagnosis source corresponding to the identification information. For example, the identification information canid carried by the diagnostic signal may be 002, and if the MCU core determines that the target diagnostic source is a remote diagnostic module according to the identification information 002, the MCU core sends the diagnostic result to the remote diagnostic module.
Optionally, if the MPU core is in an idle state, sending the target data to the MPU core, so that the MPU core can diagnose the chip according to the target data, including:
if the diagnostic signal sent by the target diagnostic source is not received within the preset time, judging that the MPU core is in an idle state, and sending the target data to the MPU core so that the MPU core can diagnose the chip according to the target data.
The preset time may be a time preset by a user according to an actual situation, which is not limited in this embodiment. Preferably, the preset time may be 10 seconds.
Specifically, if the diagnostic signal transmitted from the same diagnostic source is not received within a preset time, for example, 10 seconds, it may be determined that the MPU core is in an idle state, and the MCU core transmits the target data to the MPU core, so that the MPU core performs a diagnosis of the chip according to the target data.
According to the technical scheme, the MCU core receives the diagnosis signal, wherein the diagnosis signal is CAN protocol data, then the MCU core checks the CAN protocol data to perform decryption operation to obtain decrypted CAN protocol data, the MCU core extracts target data from the decrypted CAN protocol data, if the diagnosis signal sent by the target diagnosis source is not received within a preset time, the MCU core judges that the MPU core is in an idle state, the MCU core sends the target data to the MPU core, so that the MPU core CAN realize diagnosis of the chip according to the target data, and finally the MCU core receives a diagnosis result sent by the MPU core and sends the diagnosis result to the target diagnosis source corresponding to the identification information. Through the technical scheme of the invention, the SOC chip CAN be compatible with the function of diagnosis through the CAN bus, and the research, development and production costs are reduced.

Through the technical scheme of the invention, the SOC chip CAN be compatible with the function of diagnosis through the CAN bus, and the research, development and production costs are reduced.
Optionally, after the diagnosis of the chip is implemented according to the target data, the method further includes:
and sending the diagnosis result to the MCU core so that the MCU core sends the diagnosis result to a target diagnosis source.

The DPC module receives the diagnosis signal and determines target data according to the diagnosis signal, and if the MPU core is in an idle state, the DPC module sends the target data to the MPU core in an IPC communication mode.
