摘要
Abstract
This paper uses MPC8315E to build a development platform, introduces the features and hardware platform structure of Freescale's 32-bit microprocessor MPC8315, and gives a brief physical mapping structure of U-Boot, kernel and file system. Nand Flash capacity is larger relative to Nor Flash. The starting of U-Boot in Nand Flash can save Bootloader, kernel and file system in Nand Flash, then Nor Flash is omitted from the hardware. The paper focuses on the cutting and transplantation process of U-Boot on Nand Flash. By configuring the hardware reset word in U-Boot, and analyzing and modifying the Nand start program, the transplantation of U-Boot on Nand Flash is realized. By modifying Makefile to realize the software selective compiler and giving the cross compiler link process in Linux, the paper describes how to generate an executable document in detail.关键词
