vmware bare metal

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

autoboot ): After resetting and disabling the axd, the U-boot serial port initialization prompt (promptly press the key to stop autoboot when the first buzzer rings ): Here is the reset to use uboot to initialize the development board, but it is not clear why it is necessary to press the button on the first buzzer to enter ubootAppendix: Hardware environment: J-link V8, mini2440, J-link adapter board, serial port USB cable Software environment: Windows 7 (32-bit), Development Board uboot (n

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

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 an

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 debu

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 *) 0

Shutdown restart,--Desktop, enter the BIOS system by tapping the "delete" button--notebook, usually through "F2" or "ESC", enter the BIOS system3. Set the BIOS boot mode to USB drive--esc, return to the previous level of functionality--f10, save function--After determining, save. 4. Come to the selection screen and go to Win8 Lite5.

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, whic
