Hardware direction: I have a good knowledge of hardware, mainly engaged in hardware design, and sometimes I need to develop some bottom-level software that is most closely related to hardware, such as BootLoader, board support package (like BIOS of PC, which drives hardware downward and supports operating system upward), and the most elementary hardware driver.

Software development accounts for the main aspect of social demand, mainly engaged in the development of embedded operating systems and application software. After completing the embedded training, you can be employed in computer application design and development positions in consumer electronics, safety and security, automotive electronics, medical electronics, telecommunications and other industries, as an embedded product and application system design and development engineer, engaged in embedded technology application project design and development, product maintenance and technical services.

There is great demand for talents in both directions. After all, there are not many big cows. Zhu Youpeng is one of them. I recommend you to watch his video.
