I have been using Ubuntu for two years. From dapper-6.06 to the current hard-8.04 (it took only one month ). At the beginning, I felt that Linux technology was booming. Progress is very slow after a period of time. I think I am a beginner at the cainiao level. I also think Ubuntu masks many Linux things. I only use its shell, and then press the mouse to beat my life. . In addition, you don't even need to execute commands to use Ubuntu to install everything you have just created. Later, I learned

Development Board and start it. You can see this information in the serial port. Before the countdown to 0, press the Space key of the keyboard: Start writing: Use USB cable to connect the USB device interface and PC of the Development Board. For jz2440, use 2nd USB cables to connect the miniusb port and PC marked with the text "USB. If it is used for 1st times, a prompt will be prompted to install the dnw driver. Enter the letter "N" in the serial port, indicating "Download U-boot to nandflash

The tiny6410 Development Board supports both NAND and SD startup modes. In my understanding, it means "nc" is not connected. Om [] = 01111, boot_eint [] = 000, refer to the following table to indicate that the SD card is enabled. The switch is not described in the schematic. The LED diagram is as follows: Gpk4, 5, 6, and 7 light-emitting diodes are switched ON when the light-emitting diode is switched on. Arm Assembly MoV command 1: Syntax: 2: 3:

The following bare metal program is based on gt2440 and the compiler is a arm-linux-gcc-4.4.3. Program layout: the source code is composed of two files: interrupt. s and led. C. The interrupt is responsible for initialization, And the interrupt processing program is defined in led. C. Program process: first install the abnormal vector table, disable the Watchdog in the reset exception, then enter the normal interrupt mode, set the treasure pointer for

The following bare metal program is based on gt2440 and the compiler is a arm-linux-gcc-4.4.3. Program Structure: The program consists of SDRAM. S and Main. C consists of two files, SDRAM. s file to complete some initialization work, such as clock initialization, memory controller initialization, copy the second-stage code to SDRAM, and so on; Main. C is responsible for four LEDs which are cyclically lit and extinguished. Program process: during power

The Ethernet Control Chip dm9000 is able to receive data correctly on 2440 bare metal (the source code project has been uploaded) (411.47 K) the attachment was downloaded 168 times After a few days of dm9000, I have never been able to correctly receive data. I am so depressed for a few days. Now I am happy. I have referred to this Article "single-chip microcomputer-driven dm9000 Nic chip (detailed debugging process)". The article is very good and

Mottled marks on Metal Plates Create a layer. Filled Foreground: 200,210,215. Create a rectangular selection area in the middle. Filled Foreground: 200,210,215.

Magnifiers focus on the texture and light of the border and the handle. First, make the image of each part, then add the initial texture with the set gradient, and then use the pen and other tools to hook out the selection area of the highlight part, fill in the brighter color to strengthen the texture. You can use a layer style to enhance texture. Magnifiers focus on the texture and light of the border and the handle. First, make the image of each part, then add the initial texture with the set

Nimi2440 bare metal LED program problems-general Linux technology-Linux technology and application information, the following is a detailed description. I am a beginner. This is the code I wrote. There is no syntax error, but it is a logic error and cannot implement the desired result. Please advise !! # Define GPBCON (* (volatile unsigned long *) 0x56000010) # Define GPBDAT (* (volatile unsigned long *) 0x56000014) # Define LED1_BCL (3 # Define LED

PIN will respond accordingly. Q 1: Q 2: Does the chip selection pin need to be set manually? Answer 2: no need. When the CPU accesses an address, the CPU sends an address signal to the memory controller, and the memory controller makes the corresponding So let's say why our memory address is 30000000, because we have this time the memory controller to select the address, corresponding to the corresponding chip selection signal, select the memory chip. The address range of a single chip pin corr

Some time ago, bare metal was used on the Keil platform. Keil was not born to support both arm11 and arm11 products. It was not very easy to use, but it was still switched back to ads. The Platform should not be an obstacle that binds us. It should be our tool. It should be used when we pick it up! This blog does not teach you to start learning ads from scratch, but is just a record of my experiment, which is convenient for you and your future refer

On the iic BUS, only two lines are required: the serial data line SDA and the serial clock line SCL to complete commu

multiplication to be more complex, the vector operand on the left, the compiler is treated as a line vector, in the right is the compiler as a column vector. The number of columns on the left side of the operand must be equal to the number of rows on the right side, so the multiplication is considered legal. Examples are as follows:FLOAT3 v;float3x3 m;float3 u = m * v;//equivant to u = v.x * M[0];u + = V.y * M[1];u + = v.z * M[2];Matrices are multiplied by matrices, for example:float3x3 m, n
