Problems solved by technology

[0004] After the TV leaves the factory, it will not be possible to perform large-scale software upgrades on the back-end image quality processing chips, etc., or use the Internet to complete software upgrades by users themselves. The way to upgrade is to improve the TVs that have already left the factory
Due to the particularity of the back-end picture quality processing chip, once the upgrade fails, after-sales maintenance personnel need to remove the back cover of the TV for repair, which requires a lot of labor costs; and OTA upgrade is a large-scale upgrade method. Failure will cause a large number of TVs to have problems, which will lead to disastrous consequences. Therefore, safety measures must be taken for the OTA upgrade of the back-end image quality processing chip. still able to start normally

[0045] image 3 It is a schematic diagram of the circuit principle of the first embodiment. It does not require the software carrier of the slave processing chip, so it has a wide range of applications.

[0046] refer to image 3 Specifically, the specific circuit of the upgrading device 11 may include: one master SoC, one or more network interface modules of the master SoC, one or more slave processing chips and their software carriers.

[0047] Both the master system-on-a-chip and the slave processing chips that require software upgrades include I2C interfaces, and they are connected through the I2C bus laid out on the circuit board.

[0048] The slave processing chip software carrier adopts NORFlash without I2C interface, and the slave processing chip is connected to the corresponding NORFlash through the SPI interface. Each slave processing chip has only one NORFlash. In this embodiment, only one secondary processing chip needs to be upgraded: the back-end image qualit...

[0078] Figure 5 It is a schematic diagram of the circuit principle of the second embodiment. It requires that the software carrier of the slave processing chip must have an I2C interface, so that the scope of application is narrow but the control is simple and the efficiency is high.

[0079] refer to Figure 5 Specifically, the specific circuit of the upgrading device 11 may include: one master SoC, one or more network interface modules of the master SoC, one or more slave processing chips and their software carriers.

[0080] The main system-level chip, the slave processing chip requiring software upgrade, and the corresponding slave processing chip software carrier all include I2C interfaces, and they are connected through the I2C bus arranged on the circuit board.

[0081] The software carrier of the slave processing chip adopts NORFlash with I2C interface, and the slave processing chip and the corresponding NORFlash are still connected through the SPI interface. Each ...

Abstract

The invention relates to a slave processing chip upgrading method and device. The method comprises steps as follows: an upgrading software package is acquired from a master system chip; the upgrading software package is sent to a slave processing chip; the upgrading software package is programmed in a first starting zone of a slave processing chip carrier and upgraded, and the first starting zone is used for storing a currently used main procedure; if upgrading fails, restarting is performed through a second starting zone of the slave processing chip carrier, and the second starting zone is used for storing backup of the currently used main procedure. The second starting zone is used for storing backup of the currently used main procedure, and accordingly, starting can still be performed from the second starting zone and the originally used version can be returned even if upgrading fails.

Description

technical field [0001] The present invention relates to a method and a device for receiving and maintaining a program using the internal storage of a processing device, in particular to a method and a device for upgrading from a processing chip. Background technique [0002] In smart devices, in addition to the main system-on-chip (SOC) chip, there will also be a slave processing chip that shares part of the functions of the main system-on-chip chip. Due to the high risk of upgrading the secondary processing chip and the inability to actively restore the original driver software after the upgrade fails, the secondary processing chip is generally not set to be actively upgraded. In order to avoid control confusion and system risk, the main SoC chip and the slave processing chip generally can only control their own peripheral components, but cannot directly control other peripheral components. Since the main SoC chip cannot directly control the software carrier of the slave p...
