Embodiment Construction

[0030] In the existing BLE system-on-chip, generally its micro-processing unit copies the system program stored in the external memory, such as Flash, into the memory when it is powered on, and runs the system program in the memory. If the system program needs to be upgraded, the system will first erase the system program stored in the external memory, and then write the received system update data into the external memory through OTA. For example, between the remote control end and the host end based on the BLE connection, the remote control end will receive update data sent by the host end to implement system upgrades.

[0031] However, the problem is that when the system program stored in the external memory is erased, if an unexpected power failure occurs, the program in the external memory will be lost. In this way, the remote controller will not be able to start normally after it is powered on again.

[0032] In order to make the above objects, features and advantages of...

Abstract

The invention discloses a remote-control end system updating method and device. The method includes: starting a remote control system stored in a first storage space of a remote-control end; receiving system updating data transmitted at a host end and storing the system updating data in a second storage space of a remote control; when receiving of the system updating data is completed, performing integrity checking on the system updating data; when the system updating data passes the integrity checking, controlling the remote-control end system to quit forcibly; entering the second storage space to restart the remote-control end system. By the method and device, the problem that the system cannot be normally started due to unexpected circumferences during system updating can be avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for updating a remote control terminal system. Background technique [0002] In the existing Bluetooth Low Energy (Bluetooth Low Energy, BLE) system-on-chip, it is generally stored in the external memory, such as the system program in Flash, by its micro-processing unit when it is powered on. The system program is run in the memory. If the system program needs to be upgraded, the system will first erase the system program stored in the external memory, and then write the received system update data into the external memory through Over the Air Technology (OTA). For example, between the remote control end and the host end based on the BLE connection, the remote control end will receive update data sent by the host end to implement system upgrades. [0003] However, the problem of the prior art is that after the system program stored in the external mem...
