In ARM-LINUX-GCC, this link-mode command has the following basic form $ (cc) -static-wl,-tboot.lds,-map,system.map-nostartfiles-o boot.elf $ (OBJS) CC This is ARM-LINUX-GCC -Wl, -TBOOT.LDS,-MAP,SYSTEM.MAP-WL indicates that subsequent arguments are passed to the linker, and the arguments are separated by commas. -tboot.lds is the specified link script that plans the location

Article 1Article, Explains the basics of SOC design! Address: http://blog.163.com/gene_lu/blog/static/64025421201111872144184/ We skip all the descriptions of arm and directly go to the questions most concerned by engineers.To design an ARM-based SOC, we must first understand an ARM-based SoC structure. Figure 1 shows a typical SOC structure:Figure 1Fro

Some common abbreviations and explanations of ARM MSB: the highest valid bit; LSB: minimum valid bit; AHB: advanced high-performance bus; VPB: a large-scale peripheral bus connecting the peripheral functions of the chip; EMC: external memory controller; Mam: Memory acceleration module; VIC: vector interrupt controller; SPI: full-duplex serial interface; Can: controller LAN, a serial communication protocol; PWM: pulse width modulation; TM: Embedded

, why became 1.0, I do not know, how to compile is not difficult, difficult in how to configure, related documents please read my other document "Arm-linux Tslib", of course, which document may not help you to fix, you need to use your intelligence, You may need to read the kernel-screen-driven source code. My Development suite Touch-screen controller is the CPU itself with the ad converter, kernel driver is compatible with H3600, so I ts.conf file Mo

analysis of embedded Linux interview (I.)--ARM Part II 1. describe how the embedded ROM-based operation is based on RAM What is the difference between the operating mode. RAM-based operation: the hard disk and other media need to be loaded into the RAM, loading process generally has relocation operations;Rom based: no above operation.ROM-based: Slower than ram-based, because there will be a variable, part of the code, such as moving from memory (hard

carefully coded to be position independent.TextaddrThe kernel-initiated virtual address, which corresponds to the zreladdr. A generic kernel-initiated virtual address is the first bank address of RAM plus 0x8000.TEXTADDR = Page_offset + textoffstVirtual start address of kernel, normally Page_offset + 0x8000. This is where the kernel image ends up. With the latest kernels, it must is located at 32768 bytes to a 128MB region. Previous Kernels placed a restriction of 256MB here.TextoffsetThe kerne

The functions of the Arm-linux tool are as follows: Arm-linux-addr2lineConverts the program address to the file name and line number. Give it an address and an executable file name on the command line, and it uses the debug information of the executable file to indicate which file and line number is on the given address. Arm-linux-arCreate, modify and extract arc

The paper is recorded in the Linux environment with the cross-tool chain to develop arm bare metal programs encountered some problems and solutions, mainly to solve the problem of the process and a number of small experience, small skills recorded. Now, some of the things that feel a bit of value are moved to the blog for readers ' reference. -----------------12.16----------------- 22:25Compiling a bare-metal program using a cross-tool chain require

systems is limited, generally, you need to create a cross-compiling environment for the target machine on your powerful PC. This is a comprehensive development environment consisting of compilers, connectors, and interpreters. The cross-compilation tool consists of binutils, gcc, and glibc. Sometimes, to reduce the libc library size, you can use other c libraries to replace glibc, such as uClibc, dietlibc, and newlib. Creating a cross-compilation toolchain is quite complicated. If you don't wan

RedHat hopes to use the LinuxforARM server to avoid decades of Unix splitting. IDG News Agency-Redhat has developed a server version of the Linux operating system, which can be used to test the ARMv8-A64-bit-based chip and its peripheral hardware, is expected in the unified server market. Based on the company's Red Hat Enterprise Linux (RHEL), the release is part of a Partner Program launched by red hat on Wednesday for potential ARM hardware vendors.
