<p dir="auto">于是我搜索unknow PMU，找到了lichee/brandy/u-boot-2014.07/arch/arm/cpu/armv7/sun8iw16p1/spl/pmu_spl.c中的函数pmu_init有打印这个，但是奇怪的是我在文件头部随便输入“====”然后编译却没有编译错误，打包重新下载也没有输出我更改的printf内容。我搜索编译的log又发现编译的好像是u-boot-2018,但是搜索这个文件夹却没有地方打印unknow PMU，所以我就搞不明白了，希望大佬指点一下，这个log是哪个位置输出的。<br />

不好意思，看成了<em><strong>chip id error</strong></em></p>
<p dir="auto">这个是DDR 初始化出错,检查DDR配置，型号与开发板是否一致，有没有焊妥．</p>
