Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
At present, in an intelligent set-top box based on an Android TV system, a system when the set-top box is normally started is generally called an Android TV system, and a system used when the set-top box runs a system upgrade is called a Recovery system, that is, the set-top box based on the Android TV system generally completes factory restoration and system upgrade (specifically, factory restoration setting, OTA upgrade, firmware upgrade, and the like) of the system through the Recovery system. Due to the fact that the Android TV system has a strict selinux safety management mechanism, upgrading of requirements for partition increase, size and position change, system server increase and the like is limited, and products which are designed and shipped before by various manufacturers cannot be upgraded to the latest Android TV system normally. Therefore, the system upgrading method for the Android TV system set top box provided by the invention solves the problem of system upgrading of the shipped Android TV system set top box.
Specifically, the embodiment of the present invention is specifically described below by taking an Android TV system set top box as an example.
Example 1
Suppose the set-top box is divided into parts 1, parts 2, parts 3, parts 4, parts 5, parts 6, parts 7, parts 8, parts 9 and parts 10, and the images corresponding to the parts are stored from low to high according to the flash address. If partitions need to be added (the total amount of flash is fixed, partitions are added, and the size of the partitions needs to be adjusted certainly), assuming that the part5 partition has a margin for the system partition space, a space can be reserved for the newly added vendor partition, at this time, a part of the partition can be directly divided into vendor partitions after the part5 partition, the start addresses of other partitions are not changed, and in order not to affect the data of other partitions, the upgrade package can only contain the part5 partition and the newly added vendor partition. However, due to the limitation of the SEandroid security policy, the original Recovery system does not have the authority to upgrade the newly added vendor partition, so the Recovery system and the partition configuration mirror image are upgraded firstly, the upgraded Recovery system has the function of upgrading the newly added vendor partition, and then the upgraded Recovery system is restarted to complete the upgrading work of other partitions.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a system upgrading method for an Android TV system set top box according to an embodiment of the present invention. As shown in fig. 1, the method is applied to an Android system set top box, for example, an Android TV system set top box, and includes:
step S10: judging whether a Recovery system of the set top box of the Android TV system has the authority to complete the upgrading requirement of the Android TV system;
the Recovery system is used for system upgrading and backup of the Android TV system and can also be used for restoring factory settings. And determining whether the Recovery system needs to be upgraded or not by judging whether the Recovery system of the Android TV system set-top box has the authority to finish the upgrading requirement of the Android TV system, so that the upgraded Recovery system can meet the requirement of upgrading the Android TV system.
Specifically, the judging whether the Recovery system of the Android TV system set-top box has the authority to complete the upgrade requirement of the Android TV system includes:
upgrading test is carried out by normally manufacturing an upgrading packet, and whether the Android TV set top box system and the upgraded service can be started normally when the service is newly added is judged after upgrading;
the upgrading package is manufactured through compiling scripts, upgrading tests are performed through local upgrading, specifically, the local upgrading is that a user needs to download the upgrading package of a corresponding version through an upgrading server, then the upgrading package is copied to a U disk or an SD card, and the local upgrading is performed through system setting. Or, the upgrade test can be performed through network upgrade, where the network upgrade is performed by connecting to an upgrade server through a network, and downloading an upgrade package of a corresponding version from the upgrade server for upgrade.
After the upgrading is completed in a local upgrading or network upgrading mode, whether the upgraded Recovery system can complete the upgrading function is determined by judging whether the Android TV system can be normally started or not and whether the upgraded service can be normally started when the service is newly added.
If the Android TV system and the upgraded service during the service addition can be started normally, determining that the Recovery system has the authority to complete the upgrading requirement;
specifically, the Android TV system itself provides many system services, and when the Android TV system is upgraded, some services may be added. The service is an Android system service, namely a program running in a background such as a network management service and is used for completing a specified function. When a user needs to add some functionality, services such as bluetooth, WIFI, speedometer, and so on, need to be added. And after the Android TV system is upgraded through the Recovery system, upgrading the service, and if the Android TV system and the upgraded service during the new service can be started normally, determining that the Recovery system has the authority to complete the upgrading requirement.
And if the service upgraded when the Android TV system and/or the newly added service can not be started normally, determining that the Recovery system has no authority to finish the upgrading requirement.
Specifically, if the Android TV system cannot be started normally, or the service upgraded during the service addition cannot be started normally, or both the Android TV system and the service upgraded during the service addition cannot be started normally, it is determined that the Recovery system does not have the authority to complete the upgrade requirement. Wherein the service is packaged in a mirror image.
Step S20: if the Recovery system does not have the authority to complete the upgrading requirement, the Recovery system and the partition configuration mirror image are upgraded firstly, so that the upgraded Recovery system has the function of upgrading the Android TV system;
wherein, the upgrading the Recovery system comprises: modifying the authority configuration file, the system mounting script and the compiling script of the Recovery system to generate an upgraded Recovery system;
specifically, in order to realize partition addition and system service addition of the Android TV system, corresponding authority and configuration are required. Because the original Recovery system has no related authority and configuration, the Android TV system cannot be upgraded, and therefore, a Recovery system capable of successfully upgrading a new upgrade package is compiled at first, namely, the Recovery system is upgraded. The permission configuration file is used for setting the partition of the new Android TV system and the permission of the service of the new Android TV system. The system mounting script is used for mounting the partitions to finish the updating of the partitions of the new Android TV system. The compiling script is strictly speaking an upgrading script, and the Recovery system upgrades the Android TV system through the compiling script. The updated Recovery system can be generated by modifying the authority configuration file, the system mounting script and the compiling script of the Recovery system, so that the Android TV system can be updated by the updated Recovery system, and the updated Android TV system is generated.
Wherein the upgrading the partition configuration image comprises: and reconfiguring the partition information table, and compiling to generate an upgraded partition configuration mirror image.
Specifically, the partition configuration mirror is a mirror for storing partition configuration information, the partition configuration mirror stores a partition information table, and the partition information table is a flash partition table. Since the partition configuration information must be changed when a partition is added, the partition information table must also be changed. It is therefore necessary to generate an upgraded partition configuration image by reconfiguring the partition information table and by compiling.
Step S30: restarting the upgraded Recovery system to complete the upgrade requirement;
specifically, the upgraded Recovery system has the function of upgrading the Android TV system.
Referring to fig. 2 again, fig. 2 is a schematic flowchart of another system upgrading method for an Android TV system set-top box according to an embodiment of the present invention;
as shown in fig. 2, the system upgrading method for the Android TV system set-top box includes:
step S101: judging whether a Recovery system of the set top box of the Android TV system has the authority to complete the upgrading requirement of the Android TV system; if yes, go to step S112; if not, the step S102 is carried out;
specifically, the judging whether the Recovery system of the Android TV system set-top box has the authority to complete the upgrade requirement of the Android TV system includes:
normally manufacturing an upgrade package according to an original upgrade mode to carry out upgrade test, and judging whether the Android TV set top box system and the upgraded service can be started normally or not after upgrade;
if the Android TV system and the services upgraded when the services are newly added can be started normally, determining that the Recovery system has the authority to finish the upgrading requirement, and then, operating according to the original upgrading process of the Android TV system to finish normal upgrading, namely, directly upgrading the upgrading package of the Android TV system through the original Recovery system;
if the service upgraded when the Android TV system and/or the newly added service cannot be started normally, determining that the Recovery system has no authority to complete the upgrading requirement, wherein the original Recovery system cannot upgrade the upgrading package of the Android TV system, and the upgrading package needs to be manufactured again.
Step S102: modifying the upgrading package to make a script and making a second upgrading package, wherein the second upgrading package comprises: the method comprises the steps of a first upgrade package, an upgraded Recovery system and a partition configuration mirror image;
specifically, the second upgrade package is an upgrade package including a first upgrade package, an upgraded Recovery system, and an upgraded partition configuration image, and the first upgrade package is an upgrade package including a newly added partition, a service, and an affected related partition, for example: the second upgrade package and the first upgrade package may be zip files or rar files, such as: designating the second upgrade package as update.zip, designating the first upgrade package as update _ to _ new.zip, and creating the second upgrade package update.zip by modifying an upgrade package creation script of the second upgrade package update.zip, wherein the second upgrade package update.zip includes: zip, the upgraded Recovery system, and the upgraded partition configuration image. The Recovery system is completed by modifying the authority configuration file, the system mounting script and the compiling script of the Recovery system, and the partition configuration mirror image is generated by compiling after reconfiguring the partition information table. Zip, wherein the manufacturing process of the second upgrade package update includes: firstly, packing the newly added partition, the service and the affected related partition to generate a first upgrade package update _ to _ new.zip, then copying the first upgrade package update _ to _ new.zip to a corresponding directory, modifying an upgrade package manufacturing script, and compiling again to generate a file containing: a first upgrade package update _ to _ new.
Step S103: starting upgrading, and acquiring a second upgrading packet in a local upgrading or network upgrading downloading mode;
specifically, the second upgrade package update.zip can be downloaded to the local through the upgrade server, the local upgrade can be completed through system setting by acquiring the local second upgrade package update.zip, or the upgrade package with the corresponding version can be downloaded and upgraded by directly connecting to the upgrade server through a network.
Step S104: judging whether the second upgrade package contains a first upgrade package; if yes, go to step S105; if not, go to step S113;
specifically, the second upgrade package update.zip is obtained through a local or an upgrade server, whether the second upgrade package update.zip includes a first upgrade package update _ to _ new.zip is judged, and if the second upgrade package update.zip does not include the first upgrade package update _ to _ new.zip, the Android TV system is upgraded through a Recovery system according to the second upgrade package update.zip through a normal Recovery flow. And if the second upgrade package update.zip comprises the first upgrade package update _ to _ new.zip, determining that the Android TV system needs to be upgraded through a new Recovery system.
Step S105: judging whether the set-top box is inserted into an external storage device; if yes, go to step S106; if not, go to step S114;
specifically, since all the partitions may be changed when a partition is newly added, it is necessary to store the first upgrade package update _ to _ new. If the set-top box is not inserted into the external storage device, the first upgrade package update _ to _ new. By judging whether the set-top box is inserted into the external storage device, it is beneficial to determine whether the first upgrade package update _ to _ new.
Step S106: acquiring the first upgrade package and copying the first upgrade package to the external storage device;
specifically, the external storage device includes: the Flash Memory device comprises a USB Flash disk (USB Flash disk), an SSD (Solid State disk), an eMMC (Embedded multimedia Memory Card), an eMCP (Embedded Multi-Chip Package), an UFS (universal Flash Storage), an SD Card (Secure Digital Memory Card), a NAND Flash Chip and other devices, wherein the external Storage device can also comprise at least one buffer Memory, and the buffer Memory comprises: static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), Phase Change Random Access Memory (PRAM), and the like. The external storage device may further include at least one nonvolatile storage device including: NAND flash memory, vertical NAND flash memory (VNAND), NOR flash memory, Resistive Random Access Memory (RRAM), Magnetoresistive Random Access Memory (MRAM), Ferroelectric Random Access Memory (FRAM), spin transfer torque random access memory (STT-RAM), and the like. And decompressing the second upgrade package update.zip to obtain the first upgrade package update _ to _ new.zip, and storing the first upgrade package update _ to _ new.zip to an external storage device, so that the system upgrade function can be conveniently realized after a new Recovery system is restarted.
Step S107: comparing the partition configuration, marking the partitions with changed partition head addresses and unchanged partition sizes, marking the partitions as marked partitions, and storing the partition data of the marked partitions into the external storage device in a mirror image manner;
specifically, when a partition is newly added, the size of a part of the partition may not be changed, but only the position in the flash address is changed. Zip, marking the partition with the changed partition address but the unchanged partition address as a marked partition by comparing the partition name, the corresponding partition head address and the partition size in the partition information table of the original Android TV system through obtaining the partition name, the corresponding partition head address and the partition size in the partition configuration mirror image of the second upgrade package update, and storing the partition data of the marked partition into the external storage device in a mirror image mode. Specifically, the partition with the changed address but unchanged size is marked by a partition mark bit, and the partition mark bit is written into a partition configuration mirror image for identification. The partition zone bit is used for marking the partition, and marking the partition with the changed first address and the unchanged size of the partition is beneficial to writing the partition data of the partition with the changed address and the unchanged size into the flash address subsequently.
Step S108: decompressing the second upgrade package, acquiring a new partition configuration mirror image and a Recovery mirror image in the second upgrade package, writing the new partition configuration mirror image and the Recovery mirror image into corresponding partitions, and writing a guide identifier;
specifically, the new partition configuration image is used for storing a partition initial address and a partition size, and the new Recovery image is used for storing an upgraded Recovery system. And decompressing the second upgrade package, acquiring a new partition configuration mirror image and a new Recovery mirror image in the second upgrade package, writing the new partition configuration mirror image and the new Recovery mirror image into corresponding partitions, and writing a guide identifier. For example: and recording the boot identifier as a reboot-Recovery, wherein the reboot-Recovery is used for restarting the Android TV system to enter the Recovery system again after the new partition configuration mirror image and the new Recovery mirror image are upgraded, and upgrading the update _ to _ new.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a second upgrade package according to an embodiment of the present invention;
as shown in fig. 3, the second upgrade package 100 includes: a first upgrade package 10, a partition configuration image 20, a Recovery image 30.
Wherein, the first upgrade package 10 includes: a newly added partition 11 and an affected partition 12. Since there may be multiple newly added partitions 11, there may be multiple affected partitions 12.
The partition configuration mirror image 20 is an upgraded partition configuration mirror image, and the partition configuration mirror image 20 is used for storing a partition first address and a partition size of a partition with a changed partition first address and a unchanged partition size.
The Recovery image 30 is an upgraded Recovery image, and the Recovery image 30 is used for storing an upgraded Recovery system.
Specifically, the first upgrade package 10 has two situations, the first is an Android TV system large version upgrade set by google, for example: upgrading from an Android N system to an Android O system, wherein the first upgrade package update _ to _ new.zip needs to contain all partition images; the second is a small version upgrade defined by the manufacturer, and at this time, only the newly added partition 11, the service, and the affected partition 12 need to be packaged to make the first upgrade package update _ to _ new. The affected partition 12 only contains partitions that are affected resulting in a change in partition size, and those partitions that have not changed in size are only changed in the starting address in the Flash partition table and need not be packaged into the first upgrade package update _ to _ new.
In an embodiment of the present invention, the method further comprises: and upgrading the first upgrading packet. Specifically, the upgrade process of the first upgrade package update _ to _ new is divided into the following two cases:
in the first case: in the large version upgrade of the Android TV system, all partitions need to be upgraded at this time, and it needs to be determined whether partitions in which important data such as device information, planeady, and widevine key are written during factory production are changed, and the sizes of the partitions are generally not changed, but the change of the start address cannot be excluded. The widget is a DRM digital rights management function proposed by google, and like planeady, the encrypted rights file on the google server can be accessed through the widget key. If the partition start address changes, the partition original image data needs to be stored to avoid loss of important data by coverage, then other partition upgrading is completed according to a first upgrade package update _ to _ new.
