Abstract

The invention discloses a start-up software updating method based on a ZYNQ chip, comprising the steps of copying a software program to be written into an SD card and connecting the SD card and the ZYNQ chip; settomg the startup mode of ZYNQ chip as SD card startup, running SD card startup ZYNQ chip; reading the software program on SD card and copying the software to eMMC and Flash respectively; changing the startup mode of ZYNQ chip, restarting the ZYNQ chip, and realizing the update of startup software. A technical scheme of the invention aims at the equipment based on ZNYQ in the prior art,when updating, the steps are tedious and need special configuration of burning machine or PC. By writing the program to be updated into SD card and using SD card to realize automatic updating of startup program, the updating speed and cost of startup program of equipment can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of software starting of ZYNQ chips, and in particular relates to a method for updating starting software based on ZYNQ chips. Background technique [0002] The Zynq-7000 scalable processing platform is the latest product family to use the same 28nm programmable technology used by Xilinx's new generation of FPGAs (Artix-7 and Kintex-7FPGA). The programmable logic of the ZYNQ chip is configurable by the user and connected together through an "interconnect" module. This processing method can provide user-defined arbitrary logic functions, thereby expanding the performance and functions of the processing system. However, unlike FPGAs with embedded processors, the Zynq-7000 product family's processing system not only starts at power-on, but also configures programmable logic as needed. Using this approach, the software programming model is identical to a full-featured standard ARM processing SoC. [0003] In the prior a...
