Description

Method for Unified Downloading of Mobile Terminal and Its Modem and LINUX Chip

technical field

The invention relates to the technical field of mobile communication, in particular to a method for unified downloading of a mobile terminal and its MODEM chip and LINUX chip.

Background technique

In Android phones, fastboot is a lower-level flashing mode than recovery. Fastboot is a kind of wire flashing, which is a flashing mode that uses a USB data cable to connect the mobile phone. Compared with some systems (such as Xiaomi) card swiping, wire swiping is safer and more reliable. Recovery is a card brushing mode, which is to put the flashing package on the SD card, and then flash the machine in recovery. The way to use Fastboot is to connect the mobile phone and computer with a data cable, restart the mobile phone and switch to engineering mode, and then use the fastboot command that comes with the android development kit to burn on the PC side. Usually, the three partition images of FLASH system area, user area and startup BOOT partition in the Android system are programmed. When compiling the source code, the *.img file (that is, the related generated image) will be generated in out/target/product/xxxx/( Google's Android image generation directory) directory, only the compilation for a certain hardware can generate the boot partition. Sometimes recover.img (the recovery partition in the Android system) is also burned. recover.img is the system used in the burn mode.

At present, the mobile phone of Qualcomm 7X27 series platform has two main ARM chips, one is the linux chip used to control the Android system, and the other is the chip that handles the boot process and network protocol call function, that is, the MODEM chip. At present, in the development stage of the Qualcomm platform, the download of the android linux data is mainly provided through the FASTBOOT tool interface provided by ANDROID, and the download of the MODEM chip is realized through the QPST (a transmission software developed for Qualcomm chips) tool of Qualcomm. Personnel need to use different generation tools for different generation software according to their own development requirements, which brings great inconvenience to development. If the developer upgrades a complete set of software, he needs to first upgrade the image of the MODEM chip through the QPST tool. After the image upgrade of the MODEM chip is completed, he needs to switch to the download mode of FASTBOOT, and then download the images of BOOT, SYSTEM, and DATA respectively. . The factory download also needs 2 sets of interfaces. It uses the visualization tool to call the QPST package download interface provided by the platform when downloading the MODEM image (passing the data package through the DIAG command), and calls the QPST package tool interface to download the android linux method. mirror image.

Download AP data through the FASTBOOT tool interface provided by android, and download MODEM chips through Qualcomm’s QPST tool.

The method for unified downloading of the MODEM chip and the LINUX chip in the mobile terminal proposed according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in Figure 1, the method for unified downloading of MODEM chip and LINUX chip in the mobile terminal that the present invention proposes comprises the following steps:

Step S101, the miniaturized kernel LK enters the fast boot mode according to the instruction.

The miniaturized kernel LK is a BOOTLOADER mode before the Qualcomm platform enters the LINUX operating system, also called LITTLEKERNEL. It can be understood that the miniaturized kernel is mainly used for booting process and downloading, charging, and the LOGO logo of the initial LCD. Wherein, the miniaturized kernel LK enters the fast boot FASTBOOT mode according to the instruction, wherein the instruction includes a hotkey instruction or a mode switching instruction set in the code, for example, the hotkey is a DOWN key.

Specifically, the process for the miniaturized kernel LK to enter the FASTBOOT mode, as shown in Figure 2, includes the following steps:

Step S201, run the aboot_init function.

Step S202, judging "DetecthotkeyIf(KEY==DOWN)", if it is detected that the hotkey DOWN key is pressed, then execute step S205, otherwise execute step S203.

In step S203, it is determined to select FLASH (FlashMemory, flash memory) or EMMC (EmbeddedMultiMediaCard, embedded memory card).

Step S204, judge "GetrebootmodeIf(mode==FASTBOOT-MODE)". If yes, execute step S205, otherwise enter the inner core.

When entering the aboot_init function, Rebootmode reads the modemcore settings through the sharememory interface, and the Qualcomm platform judges whether to enter fastbootmode based on this. Fastbootmode is a passive mode, waiting for the USBhost to send a command and do corresponding processing. It is realized by accepting commands through the fastboot service inside the mobile terminal (for example, a mobile phone).

Step S205, enter the FASTBOOT mode.

Step S102, the miniaturized kernel LK obtains the identifier stored in the OEMSBL of the MODEM chip.

OEMSBL is a kind of startup BOOT of the MODEM chip, which is used to switch functions such as downloading before control. The BOOT of the OEMSBL of the MODEM chip is provided with a FLAG mark when it is not downloaded. After step S101 is executed, the FASTBOOT mode is entered, and the miniaturized kernel LK obtains the identifier stored in the OEMSBL of the MODEM chip.

Step S103, the miniaturized kernel LK judges to download the MODEM image or the LINUX image according to the identification.

In an embodiment of the present invention, downloading the MODEM image further includes: the miniaturized kernel LK sends the download information to the OEMSBL; the OEMSBL downloads the MODEM image according to the download information; and the OEMSBL updates the identification after the download is completed. Wherein, the download information includes SIZE information, partition parameter information and data information, and the download information is obtained from the miniaturized kernel LK.

In a further embodiment of the present invention, the miniaturized kernel LK sends the download information to the OEMSBL through the shared memory. OEMSBL writes the data information into the corresponding partition according to the partition parameter information, and updates the offset address. Among them, OEMSBL writes data information to the corresponding partition through the PROGRAM_IMG function in FLASH. If the writing is completed, it enters the completion state, otherwise the miniaturized kernel LK continues to send download information to the OEMSBL until the download of the MODEM mirror image is completed.

Describe the process of downloading the MODEM mirror image and the LINUX mirror image in the FASTBOOT mode in the embodiment of the present invention below in conjunction with figure.

As shown in Figure 3, the embodiment of the present invention downloads the process of MODEM image and LINUX image in FASTBOOT mode and comprises the following steps:

Step S301, write the identifier when not downloaded from the identifier area in the shared memory where the download is entered, for example, the identifier is 0XAAA5555.

Step S302, CMD_FLASH (accepts the FLASH command).

Step S303, judging "IF(DOWNIMAGE==MEDOM)", and judging whether the download of the MODEM image has entered through the set array. If yes, execute step S304, otherwise execute step S310.

Step S304, enter into the download process of the MODEM image.

Step S305, transfer the download information to the OEMBSL through the shared memory, change the flag and wait for the BOOT of the OEMSBL to download the data of this SIZE to complete.

Step S306, OEMSBL obtains the download information of LK, and resets some status flags.

Step S307, write the data into the corresponding partition through the PROGRAM_IMG function of FLASH, move the offset address down, and wait for the completion of data reception.

Step S308, "IF(*DATA==END)", judge whether the cyclic writing is completed. If yes, execute step S311, otherwise execute step S309.

Step S309, transmit the next download information to OEMBSL through the shared memory, change the identification and wait for the BOOT of OEMSBL to download the data of this SIZE to complete, and return to step S306.

Step S310 , continuing the default way of downloading images such as BOOTSYSTEM and DATA by ANDROID.

Step S311, complete.

Specifically, when a mobile terminal such as a mobile phone is powered on and enters the LK mode, that is, the system starts to run, the miniaturized kernel LK enters the FASTBOOT mode through the hotkey and the mode switching command set in the code. Before writing, set the FLAG flag when it is not downloaded in the BOOT of OEMSBL to judge the downloading stage. The miniaturized kernel LK transmits the SIZE and partition parameters and the data to be written to the partition to OEMBSL through the shared memory, and changes the flag to wait for OEMSBL After the BOOT downloads the data of this SIZE, OEMSBL obtains the download information of LK, such as size information, partition parameter information and data information, and resets some status flags. The data can be read and written to FLASH through the operation function of FLASH PROGRAM_IMG and so on. Write to the corresponding partition, and move the offset address down, wait for the completion of the data reception, and then judge whether the writing is completed on the LK side, if the writing is completed, enter the completion state, otherwise pass the next time through the shared memory Send the download information to OEMBSL, change the logo and wait for the BOOT of OEMSBL to download the data of this SIZE to complete.

The method for unified downloading of the MODEM chip and the LINUX chip in the mobile terminal of the embodiment of the present invention adopts the FASTBOOT download mode of the extended function, expands the function of the FASTBOOT download, and joins to judge whether it is to download a certain image of the MODEM, if not, continue the ANDROID default For the downloading process of the linux side of android, if it is, the data and size of the added image will be passed to the OEMSBL of MEDOM through the shared memory in a segmented manner through the shared memory, so that it can be written to the MODEM by writing the FLASH function In the mirror image, the mirror image of the MODEM part can be downloaded at the same time, such as AMSS (ie, the main mirror image of the modem chip controller), CEFS and OEMSBL codes, etc.

According to the method for unified downloading of the MODEM chip and the LINUX chip in the mobile terminal according to the embodiment of the present invention, download the mirror image of the MODEM part while downloading the LINUX chip of the Android system through the FASTBOOT tool, so that the developer can focus on development during the development stage, shorten the development cycle, In addition, through the unified download method, developers only need to download a set of tools to complete the upgrade operation of all images, thereby improving development efficiency and facilitating mass production.
