Embodiment 1
[0076] Such as Figure 4 As shown, the details are as follows:
[0077] Step 1: The mARM of the terminal device loads the QCSBL through the PBL. If the PBL successfully loads the QCSBL, go to Step 2. Otherwise, enter the download (DLOAD) mode to download the mobile phone program and then flash the phone;
[0078] Step 2: Load OEMSBL through QCSBL, perform integrity verification and / or CRC on the OEMSBL; if integrity verification and / or CRC are successful, execute OEMSBL, OEMSBL load APPSBL, and start aARM, APPSBL will open the application on the mobile terminal Program (APPS), so as to complete the boot process; otherwise, load OSBL and execute OSBL. OSBL is a copy of OEMSBL to complete the same function, and OSBL and OEMSBL are located in different BOOT partitions.
[0079] Step 3 performed in parallel with step 2: load AMSS through QCSBL, if the loading is successful, then run AMSS, otherwise, enter DLOAD mode to download the mobile phone program, and then perform flashing;...

[0081] Step 1: The mARM of the terminal device loads the QCSBL through the PBL. If the PBL successfully loads the QCSBL, go to Step 2. Otherwise, enter the download (DLOAD) mode to download the mobile phone program and then flash the phone;
[0082] Step 2: Load the OEMSBL through the QCSBL, perform integrity verification and / or CRC on the OEMSBL; if the integrity verification and / or CRC is successful, execute the OEMSBL; otherwise, load the OSBL, and execute the OSBL;
[0083] Step 3: After receiving the upgrade command, download the upgrade package of OEMSBL. If it is currently started from OEMSBL, update OSBL first according to the upgrade package, and then update OEMSBL according to the upgrade package; if it is currently started from OSBL, then update it according to the upgrade package The package first updates the OEMSBL, and then updates the OSBL according to the upgrade package.
[0084] Step 4: After the upgrade is completed, the boot process described in Embodiment ...

Abstract
The embodiment of the invention provides a terminal equipment booting and updating method and equipment, relating to the field of wireless communication. The terminal equipment booting and updating method and the equipment can be used for improving the success rate of booting the terminal equipment. In the terminal equipment booting and updating method and the equipment provided by the invention, a storage unit of the terminal equipment comprises a first guide BOOT partition and a second BOOT partition; the same system guide programs are respectively arranged in the first BOOT partition and the second BOOT partition; after receiving a boot instruction, the system guide program in the first BOOT partition is loaded, and integrity verification and / or cyclic redundancy check CRC can be carried out on the system guide program; if the integrity verification and / or the cyclic redundancy check CRC is successful, a boot process is executed according to the system guide program; and otherwise, the system guide program in the second BOOT partition is loaded, and a boot process is executed according to the system guide program loaded in the second BOOT partition. With the adoption of the terminal equipment booting and updating method and equipment provided by the invention, the success rate of booting the terminal equipment can be improved.
Description
technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for starting and upgrading terminal equipment. Background technique [0002] At present, some external multimedia card (externel MultiMedia Card, eMMC) products, such as mobile phone terminals, adopt a single OEM bootloader (OEM Secondary Bootloader, OEMSBL) solution. [0003] When the single OEMSBL solution is adopted, the activation mechanism of the mobile terminal is as follows: [0004] First, load the second bootloader (Qualcomm Secondary Bootloader, QCSBL) through the primary bootloader (Primary Bootloader, PBL), and then load OEMSBL, Advanced Mobile Subscriber Station program (Advanced Mobile Subscriber Station, AMSS) sequentially through QCSBL. If the loading of the OEMSBL fails or is wrong, the mobile terminal will not be able to start normally. [0005] Such as figure 1 As shown, the existing scheme startup process is described as fol...
