Android Deep Exploration (Vol. 1) Hal and Driver Development Fifth Chapter reading experience

This chapter provides a detailed introduction to the Minicom Serial debugging tool, which includes 4 steps, and requires Eboot erase Nandflash before burning the Android system into 5 steps. Now there are a variety of development boards on the market, we should grasp the method based on a detailed understanding of the differences between the different development boards.

This chapter also learns about the Development Board test environment, because we developed the Linux driver, no matter what method compiled, we need to test on the Development Board, because the ARM architecture of the Development Board can be in the X86 architecture of the PC in the CPU instruction and binary format is different, And the hardware required for Linux is difficult to emulate on a PC, so debug and test on the Development Board.

Development Board models and types of many, the current popular is based on the s3c6410 ARM11 Architecture Development Board, S3C6410 is a low-power, cost-effective RISC processor introduced by Samsung, it is based on the ARM11 core, can be widely used in mobile phone and image processing and other fields.

OK6410 Development Board based on Samsung's latest ARM11 processor s3c6410, has a strong internal resources and video processing capabilities, stable operation at 667MHZ above the frequency, Support MOBILEDDR and a variety of nandflash.ok6410 development boards integrate a variety of high-end interfaces, using the OK6410 board can also be used in other ways realistic Linux driver output debugging information, this is the serial communication.
