Problems solved by technology

For the current application system, the curing and upgrading of DSP programs are very inconvenient, mainly in the following aspects: (1) At present, Flash curing first needs to convert the generated . The final .hex file is burned into Flash; (2) During the DSP user program upgrade process, it is also necessary to connect the JTAG debugging tool and repeat the above process

Embodiment Construction

[0021] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0022] A DSP user program upgrade and Flash download method, comprising the following steps:

[0023] Step 1. Connect the host, FPGA, DSP and two pieces of Flash together to form a hardware environment for DSP upgrade.

[0024] exist figure 1 Among them, the host is connected to the FPGA through the PCIE interface, the FPGA is connected to the DSP through the EMIFA bus, and the DSP is connected to two Flashes through the EMIFA bus and the EMIFB bus. In the present embodiment, DSP adopts TMS320C6416 chip, FPGA adopts XC7A200T of Xilinx Company, has PCIE hard core in FPGA, host adopts general-purpose computer and communicates with FPGA by PCIE bus, FPGA communicates with DSP by EMIFA bus, and Flash1 stores DSP User program, Flash1 is connected to DSP through EMIFA bus; Store boot program in Flash2, Flash2 is connected to DSP through EMIFB. Then, f...

Abstract

The invention relates to a DSP user program upgrading and Flash downloading method. The method is characterized in that a host, an FPGA, a DSP and two Flashes are connected together; a second bootstrap program and a bootstrap service program are downloaded in an RAM inside the DSP; a Flash downloading program is downloaded in the RAM inside the DSP and operates; the second bootstrap program stored in a second Flash chip is automatically copied to the RAM inside the DSP and starts to be carried out; the bootstrap service program updates the DSP user program received from the host to a first Flash chip. According to the DSP user program upgrading and Flash downloading method, the DSP user program online updating and upgrading and Flash downloading function is achieved, a code does not need to conduct format conversion in the Flash programming process, a specialized programming tool is not needed, and the work efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of information technology, in particular to a DSP user program upgrade and Flash download method. Background technique [0002] When using DSP to develop and design, the final program code must be stored in Flash, and the program code will be moved to SDRAM or SRAM to run when the power is reset. For current application systems, the curing and upgrading of DSP programs is very inconvenient, mainly in the following aspects: (1) At present, Flash curing first needs to convert the generated . The final .hex file is burnt into Flash; (2) During the DSP user program upgrade process, it is also necessary to connect the JTAG debugging tool and repeat the above process. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a DSP user program upgrade and Flash download method with reasonable design and convenient use. [0004] The present inven...
