先看答案,再做题,为移植uboot做好充足的准备。这里需要修改两个“Makefile”文件,路数变了。
一、uboot移植前需要了解的相关知识
1、正点原子的uboot设备树文件。
路径如下:
“uboot/alientek_uboot/arch/arm/dts/”
文件如下:
“stm32mp157d-atk.dts”
“stm32mp157d-atk.dtsi”
“stm32mp157d-atk-u-boot.dtsi”。
其中:
以“stm32mp157d-ed1.dts”为母版,复制一份命名得到“stm32mp157d-atk.dts”;
以“stm32mp15xx-edx.dtsi”为母版,复制一份命名得到“stm32mp157d-atk.dtsi”;
以“stm32mp157a-ed1-u-boot.dtsi”为母版,复制一份命名得到“stm32mp157d-atk-u-boot.dtsi”;
这三个文件就是“uboot的默认设备树”,先了解uboot的设备树是什么样子,为后期移植uboot提供参考。
2、正点原子的“uboot配置文件”
路径:“uboot/alientek_uboot/configs”
文件:“stm32mp15_atk_trusted_defconfig”,它以“stm32mp15_trusted_defconfig”为母版,复制一份得到的,这就是“uboot的默认配置文件”。
3、Makefile文件
1)、位于“uboot/alientek_uboot/”目录中的“Makefile”文件
2)、位于“uboot/alientek_uboot/arch/amn/dts/”目录中的“Makefile”文件
主要是了解怎么修改“Makefile”文件。
4、“stm32mp157d_alientek.sh”的shell脚本
主要是了解“shell脚本”长啥样子,以及怎么使用它来编译uboot。
二、创建uboot工作区为“alientek_uboot.code-workspace”
1、在Ubuntu桌面,打开“Visual Studio Code”软件。
2、点击“文件”,点击“打开文件夹(F)…[Ctrl+K Ctrl+O]”,见下图:
得到下图:
3、点击“alientek_uboot”,然后点击“确定”,得到下图:
4、点击“文件”,然后点击“将工作区另存为…”,见下图:
5、输入“alientek_uboot”,然后点击保存。
得到下图:
至此,“alientek_uboot”工作区创建好了。
三、查看正点原子的uboot设备树文件
1、点击“arch”,接着点击“arm”,最后点击“dts”,见下图:
2、拖动滑块,查找“stm32mp157d-atk.dts”,“stm32mp157d-atk.dtsi”和
“stm32mp157d-atk-u-boot.dtsi”;
见下图:

八、查看“uboot/alientek_uboot/arch/amn/dts/ Makefile”
修改如下:
九、查看位于“uboot/alientek_uboot/Makefile”
修改如下:
十、在my_uboot根目录下创建“stm32mp157d_alientek.sh”的shell脚本
1、打开VSCode,点击“文件”,点击“另存为(A)”,选择“uboot/my_uboot”目录,点击“保存”。
2、编写脚本
#!/bin/bash
make distclean //清零uboot
make stm32mp15_atk_trusted_defconfig //用stm32mp15_atk_trusted_defconfig配置uboot
make DEVICE_TREE=stm32mp157d-atk all -j12 //给予stm32mp157d_alientek.sh可执行权限
见下图:
十一、使用脚本文件“stm32mp157d_alientek.sh”编译
1、在USCode中,打开终端
输入“chmod 777 stm32mp157d_alientek.sh回车” //给予可执行权限,一次即可
输入“./stm32mp157d_alientek.sh回车”,//运行脚本编译uboot
2、查看编译结果:
3、输入“ls -l”查看编译结果:
至此,移植ST公司的uboot,我们应该知道怎么搞了。
