2. 编译代码 make CROSS_COMPILEaarch64-openwrt-linux- V1
V1可以看到具体的编译命令是什么便于查看编译问题的具体原因。
PS编译过程中可能会报如下错误

[root u-boot-mtksoc]#make CROSS_COMPILEaarch64-openwrt-linux- UPD include/generated/timestamp_autogenerated.hENVC include/generated/env.txtENVP include/generated/env.inENVT include/generated/environment.hCC cmd/version.oAR cmd/built-in.oCC env/common.oAR env/built-in.oLD u-bootOBJCOPY u-boot.srecOBJCOPY u-boot-nodtb.binRELOC u-boot-nodtb.binCAT u-boot-dtb.binCOPY u-boot.binSYM u-boot.symMKIMAGE u-boot-mtk.binCFGCHK u-boot.cfgOFCHK .config
u-boot代码编译的最原始的uboot包含符号信息debug信息等等。
u-boot-nodtb.binu-boot通过objcopy留下了必要的段所以大小较u-boot小非常多。
u-boot-dtb.bin是在u-boot-nodtb.bin的基础上追加了dts/dt.dtb文件。
u-boot.bin是u-boot-dtb.bin的副本。
u-boot.symu-boot的符号表信息。
u-boot-mtk.binu-boot.bin文件通过mkimage命令处理过的文件。用于最终烧写的文件。 三. 总结 编译BPI-R3开发板uboot用的交叉编译工具链是编译openwrt产生的编译过程中可能会报openssl相关错误可以安装openssl-1.1.1n解决记得安装完openssl就运行ldconfiguboot编译完烧写u-boot-mtk.bin文件。
