1 New Project Create a new project in Quartus II (hello. PRJ) 2 Qsys Hardware System Setup Open Qsys in Quartus II: Opening the Qsys interface discovers that there is already a clk_0 under system contents as shown in. To build a minimal system, you must also add some necessary components, such as Nios II processors, JTAG, Onchip_ram, SystemID, and so on. Add Jtag: Add Nios II

1.The Nios II processor ' s JTAG Debug module provides a single, consistent method to connect to the processor using a JTAG Download cable.2. Altera BSPs contain the Altera hardware Abstraction layer (HAL), an optional RTOS, and device drivers.3.The Nios II software Build Tools (SBT) and

SOF, POF and elf sof = FPGA internal SRAM configuration data, download through the JTAG, after the implementation of FPGA hardware function, after the electricity is evaporated. POF = Configure the device flash data, download the as mode to configure the device, after power off, the FPGA will automatically read the configuration data from the configuration device, then configure the SRAM inside the FPGA to realize the hardware function of FPGA. If the design contains only the

More and more people are using Nios II. After all, NIOS II is the most versatile soft core processor in the world.NIOS eds are usually loaded together when the Quartus is loaded. Usually we use the template to build the project when we are using it.In many cases, after installing quartus, we were able to run Nios EDS,

Prerequisites: Before the plan Ahead, XPS, SDK to build Xilinx Zynq 7000 (zerdboard) on-line test of PS and PL, try to define the platform, bus and DMA, see the previous blog.Take the strike, last time. Altera's Nios II on the 3C120 chip RAM running light test.Platform: Quartus + NIOS II EDK 10,3c120+epcs16 (+) +CFI Flash + Sdram (Sram), which is standard.1, build Quartus hardware platform:The Pll+le module

This paper records some problems encountered in the use of Nios and related causes analysis and solutions, make a summary convenient for later review. I also hope to help the siege lions with the same problems. This article has been updated for a long time, encountered on the write down.I use the software version: Quartusii 13.0SP1,NIOS13.0SP1[TIPS] Some basic settings of Nios EngineeringHere's a brief intr

Operating System: Win7 bitDevelopment Environment: Quartus II 14.0 (64-bit) + Nios II EDS 14.0When using Quartus, sometimes due to backup considerations, or download other people's hardware engineering from the Internet, the hardware engineering catalog will change, resulting in Nios project can not find sopcinfo files, so that the next software development can not be done. The cumbersome approach is to cre

Hello_worldSoftware development First, create a new software folder inside the hardware Engineering folder to place the software part; open toolsàNios II 11.0 software Build Tools for Eclipse, need to workspace Launcher (Workspace) path settings, it is important to note that the path does not contain spaces, etc., and then click OK. ? New project. Click File--New->? Nios II application and BSP from template, pops up

Using cable "Usb-blaster [USB-0]", device 1, instance 0x00Pausing target Processor: not responding.Resetting and trying again:failedLeaving target processor pausedOnline summary three points cause this problem occurs: 1, the pin of the reset button does not correspond well, resulting in an error, 2, to the SDRAM CLK, and CPU CLK no lag-75 phase; 3, if the PLL output CLK, do not directly fly to the PLL input

Several settings to note in the software after switching the main memory of the Nios II CPUSometimes, we may face a situation where:1. We create a SOPC system and set the reset address and the exception address of Nios II in the Qsys to point to SRAM;2. We have created the correct Nios II software engineering and are able to operate properly3. Due to a demand (su

Sof, POF, and elf Sof = FPGA internal SRAM configuration data, which can be downloaded through JTAG. After downloading, the hardware functions of FPGA are implemented. After power loss, the hardware becomes volatile.POF = configure the flash data of the device and download it to the configuration device in as mode. When the device powers down and is powered on again, FPGA will automatically read the configuration data from the configuration device, and then configure the SRAM inside the FPGA, i

As for interrupts in Nios, interrupts are used when the 16c550 needs to be tested in a nios interrupt environment. Hardware: Add Hardware Pio in Nios, but enable interrupt function. As shown in the following: System is listed, the connection to PIO is not said. But be aware of two places: Edge type, IRQ type. The next step is software design: enable the corres

Software developmentReferring to experiment two (LED), this experiment and experiment two (LED) difference is that the system clock from 50M to become 100M. Run the result, output hello from Nios ii! in the Debug window, and the four LED lights on the board flow display, indicating the test was successful! This experiment confirmed that the board support Operation frequency is high enough to reach 100M.Experiment Code /** "Hell

Previously thought to learn FPGA will be very useful, beginning to contact with FPGA, try to use Verliog to write peripheral IP, because of their own skill is still shallow, write out mostly not too stable, dare not use. Later think why not Nios II directly run soft core, the realization of peripheral communication will be very convenient, safe and reliable, so take the development Board to learn the operation of the water lamp.
