you can also read the SD card ID, to the SD card name, set the password, change the size of a read and write, here is not more introduction, we can see the official SD card information. In the next article, I will post my own write the Micro SD card program based on the Nios II, the program in the implementation of the above features, but also increased the function of reading Csd,cid register.SOURCE program for Analog SPIhttp://blog.csdn.net/ming100

and linking bootloader, you cannot use any supported functions in the glibc library. (3) initialize hardware devices such as serial port and timer. You can output some print information before initializing these devices. (4) memory ing of the detection system. The so-called memory ing refers to specifying the address ranges allocated in the entire 4 GB physical address space for addressing the system's Ram unit. (5) load the kernel image and the root file system image, including planning the la

, VxWorks, QNX, RTEMS, Artos, and lynxos embedded operating systems. U-boot supports the processors of PowerPC, MIPS, x86, arm, NiO, XScale, and many other common systems. The development goal of the U-boot project is to support as many embedded processors and operating systems as possible. Features of U-boot: > Open source code; > Supports multiple embedded operating system kernels, such as linuxnetbsd, VxWorks, QNX, RTEMS, Artos, and lynxos; > Supports multiple processor generations, such as P

new, so you must manually check whether makefile is the same as the original project, and then manually modify the makefile. The user source management in [1] Getting started with the graphical user interface p.2-11 has the following text: Simply put, since you have used the niosii SBT, you should not manually modify the makefile. Instead, you should use the GUI or command line script method, tools should change your makefile without Manually changing it. The method used in this article,

11.0 provides a new version of the system. This is an upgraded version of the system. The system can also use the later version of the system. The new version is named qsys. In qsys, the interface changes to the following sample: Everything has to be connected by yourself. It will not be automatically connected after being added to the module as before. It seems troublesome, but it seems that the compilation speed has been improved. There are several minor issues here. After adding a three-sta

SD_CARD_Read_Byte () detect this variable to achieve slow speed SPI initialization SD card. Let's take void SD_CARD_Write_Byte (u8 byte) for instructions. // read a byte to SD-CARDu8 SD_CARD_Read_Byte(){ u8 i,byte; byte=0; for(i=0;i Because the GPIO is used to simulate the SPI bus, while the GPIO of the nio ii (100 MHz Nios/f) is slow, the speed of 25 MHz can be achieved without delay. However, you must use For a clock lower than kHz, You need to

Niosii Program How to download to flash After debugging the system, the next task is to solidify the program into nor flash (hereinafter referred to as flash) and enable it to run automatically after power-on. But what should we do? I think everyone will think of using the flash programmer of The NIOS. Yes, it is used. However, flash programmer cannot be used at will. If it is not set correctly, it cannot be used. Let's talk less about follow me.

1, the order of the driving function given by Nios is generally 1, the clear interrupt 2, write control register, 3, write the parameter Register 4, interrupt registration, 5, start to work. Since the start of the work control bit in the control register, so you will think of the last piece to write, easy, but in the DMA test found that the copy of the data at the beginning of a number of 0, and copy is not complete. The problem disappears when you se

discuss it here. I have already discussed it. Next, the address is automatically configured and the configuration is interrupted. It is the same as the previous one. Compile, wait, compile, and wait... The hardware is okay. Next we start software development. Software Development Open the nioss 9.0 IDE and compile it. Press Ctrl + B. After compilation, let's take a look at the system. h file. The following content should appear: # Define timer1_name "/dev/timer1" # define timerfill type

NiO II instances based on VHDLLiu fuqi This book introduces the knowledge of VHDL. Who can learn it with VHDL? Is there more people who want to learn it now. This book is quite good. The subsequent sections introduce the examples of the Nios, which are very detailed. You can follow the steps to learn. In this section, we not only propose a method with a timestamp, but also introduce a method to calculate the time by reading the timer register. The

This article began to formally evaluate the kit, first to take the official reference design practice practiced hand, in the previous blog post to give a reference design link: https://cloud.altera.com/devstore/board/max-10-fpga-evaluation-kit/In this page, there are several designsThe design for the Quartusii 14.1 version is as follows:L ADC/LCD Controller Design EXAMPLE:ADC/LCD ControllersL Custom Instruction for NIOS II Processor:nios II processor
