Problems solved by technology

The flash memory 130B will not be used in normal mode, but only used when programming firmware, resulting in a waste of resources
Therefore, on the whole, not only the hardware cost is high, but also the burning program is very troublesome.

Abstract

The invention provides a programming system chip device. After the present invention establishes a connection with the host computer, it uses the volatile memory originally set in the burning system chip device to temporarily store the burning program code, and in the whole process of burning the firmware, it is completely unnecessary to use the burning memory. recorder. Therefore, the present invention not only saves the hardware cost of the non-volatile memory and the burner, but also makes the operation process simple and convenient.

Description

technical field [0001] The present invention relates to a system on a chip, in particular to a burnable system on a chip device and a method for burning firmware (firmware) to the burnable system on a chip device. Background technique [0002] Figure 1A According to the prior art, it is a schematic diagram of the data flow of burning program code (loader) to the system chip through the burner (buner). FIG. 1B is a schematic diagram of data flow according to the prior art, after the microcontroller (microcontroller) executes the burning program code and connects to the host computer, and then burns the firmware required for normal mode operation to the system chip. [0003] For the convenience of description below, the programming mode (in system programming mode) mainly means that the system chip executes the programming program code to program the firmware into the non-volatile memory. The normal mode means that the system chip executes the above firmware to achieve the f...
