Embodiment Construction
[0045] In order to make the object of the present invention, the specific embodiments of the present invention will be further described below with reference to the accompanying drawings. However, the present invention can be implemented in different forms, and it is not intended to be limited to the embodiments. Moreover, in the case of an unable conflict, the features in the present application and the features in the embodiments are allowed to be combined or replaced. The advantages and features of the present invention will be more apparent from the description of the following description.
[0046] It is to be noted that the figures use a very simplified form and use non-precision ratios, only to convenient, clearly assisted in the purpose of explaining the embodiments of the present invention.
[0047] It is also required to be declared, and the purpose of the step number in the present invention is to facilitate reference, and rather than a defined order. For individual nee...

The present invention relates to the field of automatic control engineering, and provides a firmware upgrade method, an upgrade device and a boot program. The method includes: S1, a host computer parses a prepared hex file into a plurality of fixed-length binary data packets; S2, Establish a communication channel between the host computer and the firmware to be upgraded; S3, the host computer sends instructions to the firmware to be upgraded through the communication channel, so that it enters the specified boot program; S4, the host computer sends instructions to the firmware to be upgraded; The firmware to be upgraded sends the binary data packet; S5, the firmware to be upgraded accepts and verifies the binary data packet; if the verification is successful, the user program is refreshed, and if the verification is unsuccessful, the user program is not refreshed; S6 1. End the firmware upgrade process, and the firmware to be upgraded jumps to the user program entry to execute the user program. The invention can quickly and conveniently upgrade the firmware, cooperate with the remote server, and realize the remote upgrade.
Description
Technical field [0001] The present invention relates to the field of automatic control engineering, and more particularly to a firmware upgrade method upgrade device. Background technique [0002] In the control of the construction machine, DSP chip is often used as a core processor due to the good programmable performance of the DSP chip. [0003] The existing DSP chip has two kinds of bonding methods: the simulator is burn and serial port. [0004] The interface between the emulator is connected to the DSP's JTAG port by the emulator, and then connects the emulator to a computer with a burn software and the debugger. However, the connection process of this approach is slow, and when the DSP chip is installed in a narrow space, the JTAG port may not be drawn, causing the condition that cannot be burnt. [0005] Based on serial port, you need to manually manually manually, manually, to power the DSP chip, so that the DSP chip can enter the internal cured boot program, and then do...
