Abstract: 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.

Key words: embedded Linux system, Linux kernel, MPC8247, PowerPC, Device Tree Blob (DTB), bootloader
