Problems solved by technology

[0002] In the prior art, the serial interface is usually used as a standard configuration for embedded devices to upgrade software and debug. With the emergence of the USB interface, data communication and power supply and reception are combined into a standard interface, and USB has gradually become the standard for embedded devices. The only external interface, the additional serial interface is superfluous, but the function based on the USB interface also needs to be replaced by a suitable upgrade plan. The commonly used USB data communication equipment needs to be powered separately, and the software upgrade process also needs to be carried out through an independent serial port. One-way upgrade or debugging, low work efficiency, slow data transmission speed, once an error occurs during the upgrade process, the upgrade will stop, which will bring great inconvenience to the normal upgrade and use of the user's software

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] The present invention provides a method and device for online software upgrade through I2C. The embedded device is composed of an I2C upgrade service module and a firmware upgrade target module, and is connected with a firmware file server through a USB data line.

[0027] Specifically, the I2C online software upgrade process includes the following steps:

[0028] 1) Power on the system;

[0029] 2) The firmware upgrade target module initializes and starts I2C;

[0030] 3) Set the upgrade flag, restart the system to enter the upgrade mode;

[0031] 4) I2C accepts and confirms the upgrade service module firmware file information;

[0032] 5) Start I2C firmware transfer;

[0033] 6) Calculate and confirm the inspection sum;

[0034] 7) Set the firmware upgrade completion flag, notify the host that the upgrade is complete, and load new firmware...

Abstract

The invention relates to the field of software upgrading methods, in particular to a method and equipment for carrying out online software upgrading through I2C. According to the method and equipmentfor carrying out online software upgrading through the I2C, the embedded device is composed of an I2C upgrading service module and a firmware upgrading target module and is connected with a firmware file server through a USB data line. beneficial effects are that an interface is multiplexed by defining a new function on the basis of not increasing and changing an original function, meanwhile, a power supply and data bidirectional transmission function is achieved, an error processing function is automatically achieved in the upgrading process, the integrity of upgrading operation is guaranteed, and great convenience is brought to normal upgrading and use of software of a user.
