03 I graduated from an ordinary university in Shaanxi electronic information major, at that time, I knew nothing about the Linux operating system, almost none of the Linux systems actually running, after graduating from university in Beijing a university for 2 years to read the software engineering master, perhaps the school and professional reasons, I have a strong interest in software development. At the end of 04 I found an internship, in Motorola China Electronics Co., Ltd. to do mobile phone test, because there is no previous work experience, so although the test work is relatively simple but also let me learn a lot of software development process knowledge, internship for 6 months, Internship at the end of our department manager intentionally let me stay in Motorola work, because of the yearning for software development, so still proposed to resign to a well-known mobile phone design company to do embedded application software development, the mobile platform with the TI development platform, the use of the operating system is nucleus, Development tools are mainly VC. It is worth mentioning that my first formal job and my salary in Motorola internship is almost (4K or so), if at that time to stay in Motorola work, wages at least 6K above, give up a higher salary this may be difficult for some people to do. At that time although the work is rarely used Linux system development, but they have begun to study arm+linux, they spent 1250 yuan to buy a board development board, with more than 1 years of careful analysis of the u-boot,kernel, common driver, and other content, And do a lot of experimental projects, I feel a lot of feelings, so the initiation of the embedded Linux to write the book, the purpose is to learn the embedded Linux development friends to provide some practical help, so that they less detours. After discussions with Tsinghua Press, my manuscript was soon identified, the August 07 national release, the book's best-selling gave me a lot of encouragement, but also let me more determined my career planning. After that, I went to an American IC company work, the job is around the network security chip to write Linux device driver, the position is senior Software Development engineer, at this time the salary is more than 10K, think 3 years ago my salary is only 4 K more points. Therefore, the warning is still in the introductory stage of the younger brother, do not for the immediate interests and give up their ideals. At that time, a lot of students were paid more than I graduated, after 2 or 3 years of work, my income has surpassed most of the students.

Summing up my professional experience, first of all internship to let me officially into the embedded industry, although not embedded development, but also for my future to do embedded software development has laid a good foundation. Secondly, my first formal job taught me the close integration of software development with real products. In addition, I use most of my spare time to self-study arm+linux knowledge, let me more determined my own technical path. Finally, in the United States IC Company engaged in Linux device driver Development has strengthened my technical background.
