Simple use of GDBDebug the arm program using GDB + gdbserver1: simple use of GDBGDB is a powerful Unix program debugging tool released by the GNU open-source organization. Maybe you like it.Graphical interface, such as Vc, BCB, and other ide debugging, but if you are running software on a UNIX platform, youIt will be found that the gdb debugging tool has more powerful functions than the visual debugger of VC and BCB. The so-called "inchLength, size is

First, let's talk about the development of arm. It can be described as a good one to open the websites of various companies, and embedded recruitment occupies most of the positions of engineers.In the broad sense, there are only a few types of embedded systems: Traditional 51, AVR, and PIC are called embedded microcontroller; arm is an embedded microprocessor; DSP; FPGA.Objectively speaking, DSP requires mo

Song Baohua talks about the basic concepts of arm's embedded Linux porting experience 1. IntroductionArm is short for Advanced RISC Machines (a processor of advanced and streamlined command systems). It is a microprocessor intellectual property (IP) Core provided by arm.Arm has been applied in various product markets, including industrial control, consumer electronic products, communication systems, network systems, and wireless systems. ARM-based mic

), Virtual File System (VFS), and network interfaces, the Linux components and their relationships are given: The Linux kernel source code contains multiple directories:(1) arch: hardware-specific kernel code, such as arm, MIPS, and i386;(2) Drivers: contains hardware driver code, such as char, CDROM, SCSI, MTD, etc;(3) include: General header files and specific header files for different platforms, such as asm-i386, ASM-

about ARM [1]1. Arm sells only intellectual property and does not sell (physical, material) products.More than 100 companies worldwide have purchased ARM licenses, including Samsung, Freescale, NXP Semiconductors, STMicroelectronics, Texas Instruments, Toshiba,analog Device, Atmel,microsemi ...

Previously, the arm ide tool used the arm standard assembly language. Now we need to use the GNU tool. Of course we need to understand the differences between the GNU arm assembly. In fact, it is very simple. You can simply browse the document and then look at the program, or you can read the GNU arm assembly program w
