zynq 7020

Today control Miz702 Board, learned the use of Emio, encountered a little problem, after analysis and try, solved, write, for everyone reference.The first problem is that the constraint file is warning and generates bitstream error.The constraint file format given in the Development Board tutorial is as follows,After analysis and attempt, it is found that the {} symbol is not supported after get_ports, it may be caused by my Vivado2015.3 (2015.4 in the tutorial), this is only speculation, not ve

For zynq such a "arm+ Programmable logic" Heterogeneous processing system we are no strangers, and its innovation is also obvious to all of us. But for more applications to enjoy the dividends of this "innovation", making it truly "landed" requires a lot of systematic work to create a perfect ecosystem. From previous articles, we have seen Xilinx's efforts in this area, especially the iterative advanced hardware Development (VIVADO) and software devel

ZYNQ Linux Linaro System image made SD card boot 0. OverviewZynq generated uboot and normal arm device is not the same, Zynq belongs to two secondary boot uboot and then by the Uboot boot the kernel, probably means that there is a mechanism inside the ZYNQ, the mechanism can not be modified by the dial switch to control the startup mode, For example, starting fro

　　Recently I have been learning the use of ZYNQ Soc, the purpose is to respond to scientific research needs, to make a common algorithm verification platform. Presumably the idea is: ZYNQ PS End is responsible for and MATLAB and other PC data analysis and visualization software interaction: can transfer data, but also through the host Computer Configuration update hardware algorithm module configuration reg

Actually, I'll mention so

ZYNQ QSPI Controller Application NoteHello,panda1 ZYNQ QSPI ControllerThe ZYNQ QSPI controller supports three modes: I/O mode, linear address mode, and traditional SPI mode, where the linear address mode dual-chip option supports a maximum linear address space of 32MB and can be read by PS DMA.1.1 Linear Address modeLinear address mode can only be read from QSPI

The purpose of this article is mainly to use a concise method of DDR3 read and write, of course, this way every read and write needs CPU intervention, efficiency is relatively low, but this is the process of learning it.As much as possible, this series of articles makes each experiment relatively independent, ensuring the integrity of the process as much as possible and ensuring the reproducibility of the experiment. However, the use of the module or IP specific role and usage is not guaranteed

According to the Xilinx official guidance document 1078, 1079来 debug amp Mode boot more laborious, because already very old tutorials. In fact, the whole document is useful for just a few points.
