摘要
硬件平台基于应用处理器PXA310,软件平台基于嵌入式Linux的Android操作系统。首先介绍了TF卡与应用处理器的连接电路设计。然后介绍TF卡驱动程序的设计和Android对TF卡的挂载方法。在TF卡驱动程序设计中采用了SPI工作模式和FAT32文件系统,描述了FAT32文件系统的移植。最后介绍了系统调试,并展示了TF卡在视频数据采集单元中应用的设计结果。
In the paper, a hardware platform based on PXA310 application processor is used and Android operating system based on embedded Linux is used as the software platform. The paper begins with an introduction of design of connecting circuit of TF card and application processor, followed by a detailed description of TF card driver program designing and the method for mounting TF card on Android. In the design of TF driver program, an SPI operation mode and FAT32 file system are used. The transplant of the FAT32 file system is presented in the paper. Finally, the paper introduces the system debugging and gives the test results of TF card used in a video data acquisition unit of a video monitoring.
