摘要
Abstract
In this paper,the realization of memory without serial presence detection is studied based on the P2020 hardware platform.First,the function of serial presence detection during PowerPC P2020 processor startup is described.Second,the method of configuring the parameters of the memory control register and the process of making the boot image are introduced without the serial presence detection.Third,the problems encountered in the actual operation are solved effectively.Finally,after powering up the P2020 system and booting the image,it can successfully boot the U-boot,load the OS and applications,and run stably.关键词
