The ARM + LINUX route focuses on the embedded Linux operating system and its application software development goals: 1) master the structure and principle of mainstream embedded microprocessor, which is initially set to ARM9) 2) an embedded operating system must be initially set to uclinux or linux.

There are a number of ways to transfer files between different operating systems. If the network is available, you can use FTP, SFTP, NFS, SAMBA (CIFS), HTTP, and so on, and if the network is not working, you can use a file system that is supported by two operating systems, such as floppy disks, CDs, or the most commonly used FAT file systems. , you can also use

I. fat12 Fat12 is a file system used in the DOS era. It is still used on a floppy disk until now. After the fat12 floppy disk is formatted, it has two heads, each head has 80 cylinder (track), each cylinder has 18 sectors, and each sector has 512 bytes of space. Therefore, the total space of the standard floppy disk is: 2*80*18*512 = 1474560b = 1440 K = 1.44 m The structure of fat12 is as follows: 1. Boot Sector The reason why the

The file system is part of the operating system and ultimately the purpose is to manage the files.The concept of creating files in the operating system is to make it easier for multiple processes to share some data, which is stored on disk. Multiple processes can be accessed

The embedded field of Linux operating systems is facing a new challenge-general Linux technology-Linux programming and kernel information. For more information, see the following. Compared with the popularity of servers and desktop systems, Linux seems to be always cool in the field of embedded systems. Is it a bad time, or is there something hidden? In recent years, Linux has achieved great success in app

confidentiality protection; 7. SSOOS security protection. How to solve the above seven problems has become a challenge for developing secure operating systems. Currently, the server operating systems used in China mainly come from abroad (such as AIX, HP-UX, Solaris, Windows Server, and LinuxServer). Because most commercial server operating systems are not open-
