Embodiment 1
[0059] figure 1 The implementation flow of the accessory upgrading method provided by Embodiment 1 of the present invention is shown, and the details are as follows:
[0060] In step S101, the firmware of the accessory is stored in the mobile terminal.
[0061] Accessories are usually realized by Micro Controller Unit (MCU), and the memory of MCU is generally small (only 2k byte or 4k byte), so most accessories do not have wireless fidelity WIFI function, and there is no perfect file system, therefore, accessories cannot download firmware through WIFI to complete the upgrade locally like a mobile terminal, nor can they copy firmware at will like a memory card.
[0062] In view of the above-mentioned limitations of the accessory itself, in the embodiment of the present invention, the firmware of the accessory is first stored in the memory card of the mobile terminal, and then the mobile terminal and the accessory are connected through a USB cable or an OTG adapter and a USB ca...
Embodiment 2
[0094] Figure 5 It shows the implementation process of the accessory upgrading method provided by Embodiment 2 of the present invention, and the details are as follows:
[0095] The second embodiment is carried out on the basis of the first embodiment. In order to ensure that the firmware sent by the mobile terminal in the first embodiment is accurately burned into the accessory, it is necessary to verify the firmware in the upgraded accessory. If the verification is not passed, then the upgrade operation will not be performed, and if it fails, it is necessary to call step S103 in the first embodiment to perform the upgrade operation on the accessories again. Specifically, the verification process includes the following steps:
[0096] In step S501, the mobile terminal sends a firmware read request command to the accessory, notifying the accessory to wait for receiving the read address.
[0097] Specifically, the mobile terminal sends a read address READ_CMD command to the ...
Embodiment 3
[0107] Figure 6 A specific structural block diagram of the mobile terminal provided by Embodiment 3 of the present invention is shown, and for convenience of description, only parts related to the embodiment of the present invention are shown. After the mobile terminal 6 is plugged into the OTG interface, it is connected to the accessory through a USB cable, or the mobile terminal 6 is connected to the accessory through a USB cable to form a system for upgrading the accessory through the mobile terminal, and the mobile terminal sends the firmware of the accessory stored locally to the accessory , the upgrade of accessories is completed, the mobile terminal 6 includes: CPU61, and a transfer switch 62 connected to the CPU, through which the OTG adapter connected to the mobile terminal 6 or connected to the mobile terminal 6 The D+ / D- of the USB cable is connected with the i2c / uart of the CPU61.
[0108] Described mobile terminal 6 also comprises:
[0109] A firmware storage u...
