Create an arm cross-compiling environment in ubuntu10.04 In Linux, the overall process of creating the entire arm cross-compiling environment is as follows: 1. Download the source file 2. Create a compiling directory in Linux and set Environment Variables 3. Create a kernel header file 4. binutils) 5. Create an initial Compiler (bootstrap GCC) 6. Create a glibc Library 7. Create a full set of compilers (fu

In the embedded development, sometimes need to do the source level debugging, can set breakpoints, step execution, compared to each step printing printf or printk, more friendly. This debugging method is described below. GDB cross-debugging is similar to a Web browser, the local PC for the client, the remote Development Board for the server side, both sides to compile the tool chain uniformly, the version is best consistent. --TARGET Specifies the target cross compiler prefix, such as--target=

Of course, this document may not help you. You need to use your talents, you may need to read the source code of the touch screen driver in the kernel. In my Development Kit, the touch-screen controller uses the active converter of the CPU itself, and the driver in the kernel is co

This is the graduation brother's Virgo blog, I hope you do not spray!!!Due to the needs of the laboratory project, graduating brother began to study Python at 9 o ' Night (2014/11/05).

Before I installed Python-2.7.3 on a Linux machine, I didn't think much of it, thinking that the Python Premium version was backwards compatible. So
