Embodiment Construction

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] The invention is based on the function extension of the Flx software. Among them, the Flx software is based on the traditional Flashloader program by expanding and enhancing its functions, named FlashloaderX, or Flx for short; Flx not only has the basic functions of Flashloader, but also features such as break Functions such as point resuming transmission, data compression, data encryption, multiple network support, etc.; the present invention preferably relates to a breakpoint resuming transmission method, and is assisted by functions such as data compression, data encryption, and multiple network support.

[0025] Such as figure 1 with figure 2 As shown, the present invention provides a preferred embodiment of a method for resuming transmission at a breakpoint.

[0026] A method for resuming transmission with a breakpoint, which is applied...

Abstract

The invention relates to the embedded field and particularly to a breakpoint continuous transmission method. The breakpoint continuous transmission method comprises the steps of generating signature information by an upper computer before a lower computer carries out upgrade operation on a controlled device; storing the signature information and storing corresponding upgrade data used for the upgrade operation by the upper computer; storing the signature information by the lower computer; and firstly reading the signature information of the lower computer and then inquiring progress information corresponding to the signature information when the lower computer carries out the upgrade operation on the device. As the breakpoint continuous transmission method is designed, the upgrade operation is realized by adopting a signature information mechanism; and as the lower computer is unnecessary to store progress information, the upgrading efficiency is improved. Meanwhile, as the lower computer is unnecessary to store the progress information by using an extra random permanent memory, the adaptability of the method is greatly enhanced; and as the upper computer is prevented from using wrong upgrade data, the operability of an upgrade system is improved.

Description

Technical field [0001] The present invention relates to the embedded field, in particular to a method for resuming transmission at a breakpoint. Background technique [0002] By default, the IAR debugger C-SPY uses the Flash Loader program to complete tasks such as data transmission, Flash erasing and programming. The Flashloader program is an executable program developed by IAR for the C-SPY debugger, similar to the Bootloader. IAR is calling for debugging. When it is necessary to download the executable file of the Flashloader program to the RAM of the target chip, then the file to be downloaded is also placed in the RAM cache. Then C-SPY starts the Flashloader program through instructions, and it reads the programming data and then reads it. Write into the Flash of the target chip to complete the erasing and programming of the Flash of the target chip, and finally clear and release the Flashloader program and programming data in the RAM area, and start a new program to run.
