百度盘下载 buildroot-100ask_t113-pro 后，根据教程，编译
buildroot 出现 Can’t find default configuration “arch/arm/configs/sun8iw20p1smp_t113_auto_defconfig”!
搜索了一下 ，在目录 buildroot-100ask_t113-pro/buildroot/dl/linux/git/arch/arm/configs 下 是有这个文件的。
你好，请问你最后是怎么解决这个问题的？我在使用Buildroot源码（源码是在百度网盘上下载的完整压缩包）进行编译的时候，spinand镜像可以正常编译出来，如下是最后的log：

编译SD卡最小系统镜像就报错如下：

我也查找了该文件，是存在的。
buildroot-100ask_t113-pro$ find ./ -name "sun8iw20p1smp_t113_auto_defconfig"
./buildroot/dl/linux/git/arch/arm/configs/sun8iw20p1smp_t113_auto_defconfig
参考下图所示，修改 buildroot源码目录下的 .config文件
找到 箭头所指两行位置，把原来的 origin/master 修改为
dc6e999b53b3994078cff097ca569a3143660185
修改完成后，保存退出，继续执行 make 编译命令。
注意：编译过程中需要联网
