基于设备树的MPC8247嵌入式Linux系统开发

摘要

针对基于PowerPC架构处理器的MPC8247目标系统,在分析PowerPC架构设备树原理的基础上,进行了嵌入式Linux的系统开发,包括U-Boot、Linux内核、设备树对象和Ramdisk根文件系统的移植和部署等.系统的实际运行情况表明,设备树文件编写正确,系统设计合理高效.%Concerning the MPC8247 target system based on PowerPC, the device tree was discussed and an embedded Linux system was developed, including the transplant and deployment of U-Boot, Linux kernel, Device Tree Blob (DTB) and Ramdisk file system. The actual operation of the system shows that the device tree file is correct, and the system design is rational and efficient.
