ZYNQSOC firmware upgrading method and device

Abstract

The invention particularly relates to a ZYNQSOC firmware upgrading method and device. The method comprises the steps that step 1, a bin firmware upgrading file is generated; to-be-upgraded equipment is started; the to-be-upgraded equipment and a computer are connected; firmware upgrading software is run on the computer; a debug port is started, and the downloading speed is adjusted; the route of abin firmware upgrading file is designated by using the upgrading software, the size of a loading file block is selected, a to-be-downloaded firmware version and a current firmware version are compared with each other after an upgrading download instruction from a downloading computer is received by 'downloading starting' ZYNQ SOC, and downloading of the firmware upgrading file is automatically started after an instruction permitting downloading is received by an upgrading computer; block numbers which are expected to be transmitted again in an error responding message are transmitted during the above process, downloading of the file is completed, and the ZYNQ SOC is restarted automatically. The method has the advantages that the method is convenient, a machine box does not need to be opened, an embedded system of the ZYNQ SOC should be provided with serial ports, a special downloading device is not needed by at least one debugging serial port, and only a serial port wire is needed.

Description

technical field [0001] The invention relates to the field of firmware upgrading of embedded systems, in particular to a ZYNQ SOC firmware upgrading method and an upgrading device. Background technique [0002] ZYNQ SOC mainly includes ZYNQ 7000 series and other products. Zynq-7000 series is a fully programmable system-on-chip, mainly including PS (Processing System) and PL (Programmable Logic). PL adopts 28nm process; PS takes 2 ARM cores of Cortex A9 as the core, and also includes on-chip memory, off-chip memory interface (DDR) and a series of peripheral interfaces. The Zynq-7000 series integrates ARM CPU and peripherals into one chip, which makes the Zynq-7000 series have dual characteristics of processor and FPGA, and is especially suitable for software-hardware co-design. [0003] The firmware involved in the present invention includes FPGA program and ARM program. In practical applications, the firmware of ZYNQ SOC is generally stored in off-chip memory, such as SD ca...

Problems solved by technology

The JTAG port download has the following disadvantages: (1) The download rate is relatively slow; (2) In general, the JTAG port is not reserved on the device panel, so the firmware upgrade needs to open the chassis; (3) The firmware upgrade needs to install the VIVADO integrated development environment computer, the program is relatively large and requires professionals to use; (4) requires a special download tool
