虚拟构建X86-64 ubuntu/debian环境，可交叉编译应用（包含u-boot等）

jack_admin

本机也可以直接编译u-boot源代码。

补充安装依赖，再更新编译脚本

sudo apt install device-tree-compiler python2

@jack_admin
这个具体怎么操作我在coolpi4b上面编译loader 编译不通过

george

@jugg 默认boot_merger这个二进制是x86架构的，需要更换为aarch64架构。你可以先再X86上面编译。或者使用下面的文件：
uboot.rar

这个是CM5的能更新开机logo的吗?
