A zynq-based single-board or multi-board system and online update method

Abstract

The invention discloses a single-board or multi-board system based on ZYNQ and an on-line updating method. The system comprises one or more ZYNQ boards, wherein each ZYNQ board comprises at least one ZYNQ equipped with an Ethernet controller, a DDR3 controller and a QSPIFLASH controller; each Ethernet controller outwards expands at least one gigabit Ethernet port through a PHY chip or a network switch; a 1GBDDR3 memory is externally arranged on each DDR3 controller; two 128Mb QSPIFLASHs are externally arranged on each QSPIFLASH controller; an upper computer generates a program file for ZYNQ configuration, the program file is sent to each DDR3 memory via the network for caching, then each ZYNQ executes instructions of erasure, write-in and the like sent by the upper computer, and data stored in each DDR3 memory are fixed in FLASH. The method realizes on-line updating of each ZYNQ is realized by using the Ethernet interface, and is simple to use and high in universality; meanwhile, when multiple ZYNQ boards exist in the system, the ZYNQ boards are interconnected through network switches, and one Ethernet interface updates programs of all the ZYNQ boards. The ZYNQ updating speed of the method is 7-8 times that the traditional JTAG programming method.

Description

technical field [0001] The invention belongs to the technical field of computers, and relates to a ZYNQ system and an online update method, in particular to a ZYNQ-based single-board or multi-board system and a remote online update method. Background technique [0002] ZYNQ-7000 is based on Xilinx fully programmable scalable processing platform structure, which integrates a dual-core ARM Cortex-A9 multi-core processor processing system (Processing System, PS) with rich features and Xilinx programmable logic in a single chip (Programmable Logic, PL). The dual-core ARM Cortex-A9 includes on-chip memory, external memory interfaces, and a rich set of I / O peripherals. The PL in ZYNQ-7000 adopts FPGA technology of Xilinx 7 series to expand functions to meet specific functional requirements. [0003] After ZYNQ completes the power-on reset, the ARM Cortex-A9 processor system needs to initialize the corresponding peripheral resources, such as network, DDR3, etc., and some applicat...
