Embodiment Construction

[0026] DSP program solidification method of the present invention specifically comprises the following steps:

[0027] Step 1. In CCS, load the common object format file (COFF) generated by the target project compilation link that needs to be programmed into FLASH into the memory space of DSP; use the GEL function provided by the GEL script tool provided by CCS to access the DSP memory, Read out the code segment and data segment of the target project separately, and save them in the hard disk of the computer in the form of data files;

[0028] Step 2. Use another GEL function to import hard disk files to combine the two data files and import them into the non-startup code memory space of the DSP. At this time, the code segment and data segment of the target project have been completely imported into the DSP. In memory data space, they can be accessed by DSP as data;

[0029] Step 3. By loading the GEL function, load the executable binary file responsible for programming FLASH...

Abstract

The invention belongs to an unmanned plane flying control system and relates to a DSP reliable on-line FLASH programming method based on a GEL script. According to the method, the following processes are automatically achieved through the GEL script, namely a code segment and a data segment of a DSP target project executable file are stored in a local hard disk first, then the code segment and the data segment of the DSP target project executable file in the local hard disk are loaded into a DSP piece external RAM, finally an executable file of a DSP programming FLASH project is loaded into the RAM, the project carries out CRC on the code segment and the data segment which are loaded to the DSP piece external RAM, the checking results are written into the piece external RAM together, then the data segment and the code segment are programmed into a FLASH, a programmed FLASH space is checked, checking results are compared with the checking results in the piece external RAM, if the results are equal, programming is right, otherwise, programming is wrong, and the programming process and the programming results are displayed in a CCS interface.

Description

technical field [0001] The invention relates to a DSP (Digital Signal Processor) technology, in particular to a method for burning FLASH online by using the DSP. Background technique [0002] At present, DSP has been widely used in wireless communication, speech recognition, multimedia, Internet and national defense fields with its powerful real-time data processing capabilities. As the first to launch the world's first DSP, Texas Instruments (TI for short) is constantly innovating and improving the development environment. With its strong strength, it has achieved about 50% market share in the industry. Among its many models of DSPs, TI classifies the DSPs with good market sales and promising prospects into three major series and vigorously promotes them. TI also calls them the three major platforms. These three series of DSP not only have different hardware structures, market positioning and application fields, but also have their own advantages and disadvantages in onlin...
