zynq petalinux

by Adam TaylorStarting last week's blog, we have entered the programming of the OLED display module on the Zedboard (instead of the microzed) board. Before formally entering the specific OLED program, however, I think it is necessary to verify that we have configured the SPI port correctly for the application. This action can be a lot less time for our next steps, and it's easy to do. In fact, it's really simple, and I'll show you two different ways in this blog post. The first method uses the

This explicit exporting can and debugging (by making some kindsof experiments easier), or can provide an always-ther E interface that ' ssuitable for documenting as part of a board the support package.

The Axi full name advanced Extensible Interface is an interface protocol that Xilinx introduced from the 6 series FPGA, primarily describing the way data is transferred between the master and slave devices. Continue to use in Zynq, version is AXI4, so we often see AXI4.0,ZYNQ internal devices have Axi interface. In fact, Axi is a part of the AMBA (Advanced microcontroller bus Architecture) proposed by arm,

This article describes how to develop a PS bare metal application on the Qaq platform through Vivado IDE. By comparing with this series of blogs (3), readers will see that Vivado development is more efficient and fast. We have heard of MP3. Now we can use ZED-Board to listen. The audio chip ADAU1761 is available on the board for recording and playing, but not MP3 decoding. Q dual-core arm9-do MP3 software decoding should be possible, but the blogger himself has a VS1003 which can implement MP3

The accelerator conformance interface on the ZYNQ PS (Accelerator coherency Port, ACP) is a compatible AXI3 64-bit slave interface that connects to the SCU (Snoop Control Unit), providing the PL with asynchronous cache consistency for direct access to PS portals.The processor can flag the transport on the ACP as either consistent or non-consistent. The Axi host on the PL side via arusers[1:0] Indicates whether the read transmission is consistent, via

the FPGA, the specific types of FPGA contains how many devices, you can refer to the Xilinx documentation.For the built-in IP, the first thing to consider is the clock module MMCM, the general FPGA will have several to dozens of clock modules, such as the following table 2000T contains 24 CMTs, which is 24 PLL and MMCM, each set of PLL and MMCM can be a clock domain clock frequency multiplier. The general ASIC will contain multiple clock domains, each of which requires at least one CMTS to oper

http://blog.chinaaet.com/detail/36014Vivado is the latest Xilinx FPGA design tool that supports the development of FPGA and ZYNQ 7000 in the 7 series. Vivado can be said to be a completely new design compared to the previous Ise design suite. Whether from the interface, settings, algorithms, or from the user's idea of the requirements, are brand-new. Looking at a lot of blog posts, basically using the GUI to create the project, then I will briefly int
