In the command line, give it an address and an executable file name, and it will use the debugging information of this executable file to indicate which file is on the given address and

support for the crossover environment, providing additional functionality to facilitate the development of embedded applications. Click Next to the "Select Configurations" page, and we take the default, direct next step, to the "Cross GCC Command" setting. Here we can fill in the Cross compilation tool chain of the prefix and path, such as: Cross compiler prefix:arm-arago-linux-gnueabi- Cross compiler path:/data/linux/ti-sdk5/linux-devkit/bin The example above is the cross compilation package

some variable storage space. However, because many controllers, such as DSP, arm, and other high-end single-chip microcomputer, do not have a location-addressable area, they need to implement a data structure similar to a location operation, you need to perform operations such as bit or shift on the byte where the current BIT is located. In this case, whether the code is beautiful or not, the amount of generated code is too large, and the CPU cycle

Eabi (Embedded Application binary Interface), binary interface of embedded applications. AbiDefinition Abi describes the underlying interfaces between applications and the operating system, between applications and libraries, and between application components. Abi allows compiled target code to run in a system compatible with Abi without any changes.

When I wrote "getting started with the neon iPhone", I thought that the reader had a better understanding of the processor knowledge of iOS devices. However, after reading some discussions on the internet, I found that the original knowledge is not popular, and it is my fault. In addition, I think understanding these things is helpful for iPhone programming (not just for those who like neon). Even if you are using objective-C, even if you are not familiar with it, it will not affect your work, b

I. ARM instructions in the hopperARM processors do not say much, the ARM processor because of low power, and so on, so most of the mobile device is basically the arm architecture of the processor. Of course, as a mobile device for Android phones, the iphone is also used with the arm architecture of the processor. If yo

Part of oscilloscope Development The dynamic link library of zlg is used for dynamic loading. Arm is Context-M3-1343. PC communication software developed in C ++ Builder 6. The USB communication code is as follows: // ----------------------------------------------------------------------------- For details, see www.jxust3jia1.com, which describes the oscilloscope project.

The first part of Linux under the ARM assembly syntaxAlthough it is convenient to write programs in C or C + + under Linux, the Assembly source program is used for the most basic initialization of the system, such as initializing the stack pointer, setting the page table, and manipulating arm's coprocessor. After initialization is completed, you can jump to C code execution. It should be noted that the GNU assembler follows the ATT assembly syntax and

-Vic in armA:If the code is run in the On-chip RAM and the application needs to call the interrupt, the interrupt vector must be re-mapped to the flash Address 0x0. This is done because all the abnormal vectors are located at the address.0x0 and above. This is achieved by configuring the register memmap (in the system control module) to the user Ram mode. User code is connected to enable the interrupted vector table to be loaded0X4000 0000. 4. Arm sta

Learn embedded well, you have to do more hands-on, more practice. To get started, configure your own development environment and migrate the kernel. The development environment does not say that the porting kernel will have to compile the kernel first. You have to have a compiler. Because the architecture of arm CPUs is not the same as x86. The usual practice is to use the arm cross compiler in the x86 deve

, 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.
