Prepare for development on the arm + linux Platform

Prepare for development on the arm + linux Platform-general Linux technology-Linux programming and kernel information. For details, refer to the following section. The following preparations for arm + linux Platform development are for developers.

I. Preparation for hardware development

1. Single Chip Microcomputer knowledge or computer principles.

2. Digital Circuits and analog circuits.

3. familiar with the principles of arm7.

4. There will be one or two EDA software (such as PROTEL 99SE and POWERPCB ).

5. Better understanding of hardware control and read/write principles such as SDRAM, nand flash, nor flash, serial port, USB, network, and LCD. Of course, some people do not understand these principles, but they can also be designed by drawing on others' designs. I just know it, but I don't know why.

6. Strong learning and understanding skills.

With these foundations, you can develop and design the hardware of the arm application.

Ii. Preparations for bootloader, linux, file system migration, and underlying driver development

1. Single Chip Microcomputer knowledge or computer principles.

2. Digital Circuits and analog circuits.

3. C, C ++, and assembly language basics.

4. familiar with the principles of arm7.

5. Familiar with the principles, configurations, compilation, and compiling and loading processes of bootloader, linux kernel, and linux file systems.

6. Familiar with hardware control and read/write principles such as SDRAM, nand flash, nor flash, serial port, USB, network, and LCD.

7. Strong learning and understanding skills.

3. Preparations for linux Application Development

1. Familiar with the operating principle and mechanism of the linux operating system, and familiar with the process and thread mechanism.

2. Have the c and c ++ language basics.

3. Some involve serial port, usb, network, and database programming, so the corresponding foundation is required.

4. Strong learning and understanding.

The above are the basic and prerequisites for developing the arm + linux Platform, which may contain errors or omissions. Comments.

I divide it into three parts. Hardware, drivers, and application development. If you can do this in three ways, it must be all talents. As arm + linux development involves too many aspects, the entry threshold is higher than that of single-chip microcomputer development. Once you are familiar with the development process, it is not as difficult as you think.
