Those skilled in the art may select some or all of the functional modules, units or subsystems according to actual needs to achieve the purposes of the embodiments of the present invention, and in this case, those skilled in the art may understand and implement the present invention without any inventive effort.
As shown in fig. 3, the basic principle of the diagnosis apparatus for transmitting EOL configuration code information is: when the production line is produced, firstly, EOL configuration codes are imported into the SOC through a diagnostic instrument, after the EOL is imported into the SOC through the diagnostic instrument, the SOC side can send EOL configuration code information to the MCU, then the MCU can store the acquired EOL configuration codes into Flash for backup, the EOL configuration codes are stored in a partition of the SOC side for being matched by QNX side driving, QNX side application, android side driving and android side application according to the EOL configuration codes, if the partition is cleared or the EOL configuration codes in the partition are lost through the brushing machine, the SOC sends a request to the MCU, and the configuration codes backed up in the MCU are synchronized into the partition of the SOC.
The schematic block diagram for acquiring and transmitting EOL configuration codes shown in fig. 4 includes an EOL writing process and an EOL acquiring process, where the EOL writing process includes a diagnostic apparatus writing and a factory test App writing:
the diagnostic instrument writes: the SOC side is a QNX+android dual system, the input end of EOL is a diagnostic instrument, and the diagnostic instrument passes through DOIP protocol. And the diagnosis SERVICE informs the CarService SERVICE of the diagnosis SERVICE by the VDC to the Android system, the CarService SERVICE forwards the EOL configuration code to the SERVICE SERVICE of the MCU by using the socket communication module, the SERVICE SERVICE of the MCU writes the EOL configuration code into the MCU, and the EOL configuration code is submitted to the EOL configuration code synchronization SERVICE after the EOL configuration code is successfully written, so that the EOL configuration code is synchronously stored in the oemcfg partition at the SOC side.
Factory test app write flow: in the process of factory testing, the same host is used for brushing different EOL configuration codes for testing, then as shown by blue arrows in the detailed block diagrams of acquiring EOL and transmitting EOL, the factory testing app can transfer the modified value to an application adaptation layer, and then the application adaptation layer is transferred to a card SERVICE, which uses socket communication to forward EOL to an MCU SERVICE. MCU SERVICE writes EOL into MCU, after writing successfully, then sends to EOL synchronization SERVICE, and stores EOL to oemcfg partition at SOC side synchronously.
Noun interpretation: the Carservice service is one of core services of the vehicle-mounted Android system, and all applications need to inquire and control the state of the whole vehicle through CarService. For example: speed, gear, ignition status, etc. of the vehicle.
The services in CarService are essentially implementation classes of AIDL interfaces, belonging to the Server side, and the corresponding Client side needs an IBinder object to access the method of the Server side, and the IBinder objects are encapsulated in different Manager classes in the CarAPI. Android O/P provides a series of services for an automatic scenario, which are commonly referred to as CarService. They communicate with the Vehicleshal of the HAL layer and further communicate with the vehicle body through the vehicle-mounted bus (for example, CAN bus), and at the same time they provide an interface for the APP of the application layer, thereby enabling the APP to realize control and status display of the vehicle body
OEMcfg partition: the underlying unit (unit) of the OEMcfg partition, also referred to as a CDT partition, is CDB (configuration data block), each CDB being a user-defined block of data, the OEMcfg partition essentially being a table of multiple or single CDBs and metadata about the CDBs. Generally consists of three parts: CDT Header, metadata partition, and CDB data partition. The partition is typically loaded into the asinfo info at boot-up, matching the program according to the board id within the partition, typically no more than 2Mb in size.
The QNX side driver shown in fig. 5 uses EOL configuration codes to perform a device compatible process, which specifically includes:
EOL acquisition flow: QNX side drive uses EOL compatibility: the screen, audio frequency and other peripheral equipment can distinguish high configuration and low configuration through the information in the EOL configuration code so as to load different driving codes and realize code compatibility.
And in the starting stage, acquiring EOL configuration code information through a partition reading interface, loading a default driving code by each driver if relevant information of the EOL configuration code does not exist in the partition (the case is used for the condition that the EOL configuration code in the partition is cleared or the EOL configuration code is imported through a diagnostic instrument for the first time), acquiring the backup configuration code in the MCU if the backup configuration code in the MCU is not empty at the moment, writing the backup configuration code into an OEMCFG partition, and starting to wait for the diagnostic instrument to input the EOL configuration code if the backup configuration code is empty.
And in the starting stage, acquiring EOL configuration code information by a partition reading interface, and if the acquired EOL configuration code information in the partition is not null, loading different driving codes by each peripheral through the corresponding configuration codes.
The QNX side application as shown in fig. 6 obtains the flow of EOL configuration code: the EOL synchronization SERVICE is a PPS publisher, other applications on QNX sides such as MCU SERVICE are PPS subscribers, and the EOL synchronization SERVICE obtains EOL configuration code content from the OEMCFG partition and publishes the EOL configuration code content to the subscribers.
Noun interpretation: the PPS service of QNX is operated as a push type publishing system; that is, the publisher will push the data into the object and the subscriber will read the data upon notification or at leisure, such as car-end, mobile-end update messages.
As shown in fig. 7, the invention further discloses an electronic device and a storage medium corresponding to the EOL configuration code processing method and system based on the method and system:
