Problems solved by technology
During this process, the system needs to be restarted several times, and when the DSP chip is installed inside the device, the programming operation is extremely inconvenient
[0006] Therefore, neither of the above two programming methods can meet the convenience requirements of current users for programming / upgrading firmware programs.

The invention relates to the field of automatic control engineering, and provides a firmware upgrading method, an upgrading device and a boot program. The method comprises the following steps: S1, analyzing a prepared hex file into a plurality of binary data packets with fixed lengths by an upper computer; S2, establishing a communication channel between the upper computer and firmware to be upgraded; S3, sending an instruction to the firmware to be upgraded through the communication channel by the upper computer, so that the firmware to be upgraded enters a specified boot program; S4, sendingthe binary data packet to the firmware to be upgraded by the upper computer; S5, receiving and verifying the binary data packet by the firmware to be upgraded; if the verification is successful, refreshing the user program, and if the verification is not successful, not refreshing; and S6, ending a firmware upgrading process, wherein the firmware to be upgraded jumps to a user program entrance toexecute the user program. Firmware can be upgraded rapidly and conveniently, and remote upgrading can be achieved in cooperation with a remote server.
Description
technical field [0001] The invention relates to the field of automatic control engineering, in particular to an upgrading device for a firmware upgrading method. Background technique [0002] In the control of engineering machinery, due to the good programmable performance of DSP chips, DSP chips are often used as the core processor. [0003] The existing DSP chips have the following two programming methods: emulator programming and serial port programming. [0004] Programming through the emulator requires connecting the interface of the emulator to the JTAG port of the DSP, and then connecting the emulator to a computer equipped with programming software and a debugger driver. However, the connection process of this method is relatively slow, and when the DSP chip is installed in a narrow space, the JTAG port may not be able to be drawn out, resulting in a situation where programming cannot be performed. [0005] Programming through the serial port requires manually grou...
