Example 1
As shown in fig. 1, the present embodiment provides a decoupling development method of system firmware, which includes the following steps:
Acquiring an OTA packet compiled and generated by an android underlying system and taking the OTA packet as an OTA parent packet; and after the development of the bottom layer system is finished, generating an OTA mother packet, wherein the OTA mother packet stores bottom layer system data. Therefore, the underlying system data can be separated for later application data update.
Unpacking the OTA parent packet to obtain compressed files of each partition; the partition compressed files at least comprise a first compressed file for storing the underlying system data and an empty second compressed file for storing application update data. Because the OTA parent packet includes a partition compressed file, for example, a first compressed file, that stores the underlying system data, the OTA parent packet further includes an empty second compressed file that stores application update data. In this way, the application update data can be updated to the second compressed file each time the application update data is received later. Each time the data is updated, the data can be updated once based on the second compressed file in the OTA parent packet. By separately storing the storage bottom layer system data and the application update data, the independent update of the application update data can be realized, and further the decoupling of the bottom layer system development and the application layer development is realized.
After the application updating data are obtained each time, decompressing the second compressed file, converting the second compressed file into an image file, then mounting the image file under a preset catalog, and copying the obtained application updating data into the preset catalog. And in the test process, the APP layer sends updated application data to the underlying system every time based on the updated application data. After the bottom layer system acquires the application update data, the application update data is stored in a second compressed file of the OTA parent packet, and then the updated OTA is regenerated. And each time the APP layer is updated, generating an updated OTA based on the OTA parent packet.
Generating an image file from the preset catalogue stored with the application updating data and compressing the image file to obtain an updated second compressed file; after the preset catalogue storing the application updating data generates a new image file, the new image file automatically covers the image file generated in advance, and then the new image file is compressed brotli, so that an updated second compressed file can be obtained.
And merging the updated second compressed file with the rest partition compressed files comprising the first compressed file, re-compressing, and re-signing after re-compressing to obtain the updated OTA packet.
It should be noted that: because the first compressed file stored with the underlying system data is not updated in the process of late application update, in principle, customized modification can be made based on a certain stable version of the application software, but the second compressed file before update needs to be deleted or replaced when the second compressed file is updated, so that the operation is complicated, a special OTA mother package can be used for facilitating the application update, the OTA mother package comprises an empty second compressed file, the application update data can be directly stored when the application update is convenient, and the operation is greatly facilitated.
Further, the first compressed file at least includes a compressed file of system partition data and a compressed file of original design manufacturer data, and the compressed file of system partition data and the compressed file of original design manufacturer data are both used for storing the underlying system data.
The second compressed file at least comprises a compressed file of third party manufacturer data, and the preset directory comprises an app directory;
Copying the received application update data into the preset catalog comprises: the application update data is copied into the app directory.
And when the application updating data further comprises library files of a third party, the library files of the third party are respectively copied into the lib catalogue and/or the lib64 catalogue according to a platform architecture. When the platform architecture is armeabi-v7a and the like, copying the library file of the third party into a lib catalog; when the platform architecture is arm64-v8a, the library files of the third party are copied into the lib64 catalogue, or the library files of the third party are simultaneously copied into the lib catalogue and the lib64 catalogue.
The method comprises the steps that an app directory of third-party manufacturer data is used as a directory of preset applications, and when application update data is acquired, the application update data is copied to the app directory of the third-party manufacturer data, so that the preset applications under the app directory of the third-party manufacturer data can be automatically installed when an android system is started; the lib catalogue and the lib64 catalogue are used for placing library files of the third party manufacturer data and are used for calling application programs in the third party manufacturer data.
The step of generating the image file from the updated preset catalogue and compressing the image file is specifically as follows: and generating an image file from the updated preset catalogue, and then compressing brotli.
The recompressing the updated second compressed file and the remaining partition compressed file including the first compressed file to obtain an updated OTA packet includes: and merging the updated second compressed file with the rest partition compressed files comprising the first compressed file, then recompressing the second compressed file, and performing re-signing to obtain the updated OTA packet.
The method for obtaining the OTA package compiled and generated by the android underlying system and serving as the OTA parent package further comprises the following steps: and building an automatic construction server, wherein the decoupling development method is executed through a script of the automatic construction server.
The obtaining the OTA package compiled and generated by the android underlying system and serving as the OTA parent package comprises the following steps: and acquiring the OTA package compiled and generated by the android bottom layer system from the local area network online warehouse. After the development is completed, the bottom layer system compiles and generates an OTA mother packet and pushes the OTA mother packet to an online warehouse of the local area network.
The method further comprises the following steps after obtaining the updated OTA packet: pushing the updated OTA packet to a networking online warehouse. The local area network online warehouse is an http server.
After the development of the android underlying system is finished, an OTA parent packet is generated, and the android underlying system only generates an initial OTA parent packet. And the application update data is received every time later, the application update data is updated according to the OTA parent packet originally generated by the android underlying system, an updated OTA packet is generated every time and pushed to the networking online warehouse, so that the equipment for conveniently running the APP can directly acquire the latest OTA packet from the Internet for upgrading.
