将u-boot-2016.11移植到TINY4412

来源：互联网发布：淘宝网购买泓铭软件编辑：程序博客网时间：2024/06/05 09:02

在工作之余显得有点无聊，就想着将u-boot-2016.11移植到TINY4412上试一试，下面是自己的移植过程，也当作一个学习笔记吧，记录记录下步骤和自己解决问题的过程。

移植之前也看了一写博客，因为想支持uboot的spl，所以就选择origen左右模板移植一个uboot到tiny4412上

1. 首先我们在终端上通过find -name "origen" 看和origen相关的文件有哪些，然后将这些文件或者文件夹复制成TINY4412。

上面的图修正一下， ./board/samsung/tiny4412/tools/tiny4412.c 重命名为mktiny4412spl.c

2. 修改相关文件的内容

这一步其实也很简单，我们这边在终端通过 grep -insr "origen" 查看和origen相关的内容，然后模仿origen，将origen字眼改成tiny4412即可。

2.1 修改顶层目录的makefile

到了这里，所有内容基本就修改完毕了。

但是后来在我编译的时候发现，出现了编译异常，但是从结果来看，所需要的文件都编译出来了，所以这一点我现在也不是很清楚原因，不过根据报错的提示：

是需要在合适的Kconfig文件中添加CONFIG_TINY4412 这个配置选项，所以做了如下修改

diff --git a/board/samsung/tiny4412/Kconfig b/board/samsung/tiny4412/Kconfigindex 06a7905..04658fe 100644--- a/board/samsung/tiny4412/Kconfig+++ b/board/samsung/tiny4412/Kconfig@@ -1,5 +1,9 @@ if TARGET_TINY4412 +config TINY4412+       default y+       bool "For CONFIG_TINY4412"+ config SYS_BOARD        default "tiny4412"

根据我现在的理解，添加的这config配置并没有实际的使用意义，应该不会对其他内容产生影响，暂且这样修改吧。

好的，修改就到这里了，这些修改只是能够让编译能够通过了，但是离能在tiny4412上面运行，还有很长一段路呢。
