Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0044] Such as figure 1As shown, the DSP chip online upgrade system of the present invention includes a COFF file analysis module, a command operation module, an application program download module, a status information module, and a CAN communication module arranged in the host computer, and a secondary boot arranged in the lower computer DSP chip. Startup module, user program upgrade module. After the COFF file parsing module parses the COFF file, the extracted segment data is subpackaged and sent to the DSP chip through the CAN communication module. The command operation module of the upper computer sends commands such as upgrading, detecting, erasing, writing, and exiting to the lower computer DSP chip through the CAN communication module. The application program download module sets the three-time detection process of the host computer, and sends the data segm...

Abstract

The invention discloses an online upgrading method for a DSP chip. According to the upgrading method, the DSP chip of each node is subjected to online program upgrading through a CAN communication bus; and the DSP chip is a DSP chip of TMS320F2833x series. The DSP chip of each node is subjected to the online program upgrading through the CAN bus, so that the efficiency and speed of performing online upgrading and program replacement on a target board are greatly improved, and a complex program writing process and inconvenience caused by embedded box packaging are avoided.

Description

technical field [0001] The invention relates to a DSP online upgrading method based on CAN communication. Background technique [0002] At present, there are several ways to burn DSP programs: [0003] Emulator burning program: first connect the emulator to the JTAG interface of the DSP, and at the same time connect it to the computer with the emulator driver and CCS application software installed. However, the embedded device in this way is inconvenient to connect to the JTAG port in the airtight box, which will bring great inconvenience to the upgrade, and the limited programming speed leads to the limited communication speed, which cannot meet the needs of users. [0004] Select the chip boot program through the DIP switch on the target board, and download the program using SPI\SCI serial port and other communication methods. Because this method needs to select the DIP switch and operate the target board, once the controller is sealed, it is no longer convenient for use...
