[ 1.372518] ALSA device list:我的版本USB 启动失败 ，请问你们用的是linux哪个版本呢
和这个 https://whycan.cn/t_2002.html 有点像,
感觉应该是编译根文件系统的 toolchain 有问题。
按这个帖子， https://whycan.cn/t_2002.html#p13502 一个一个替换试一试，
先从 rootfs 开始替换

linux内核编译Tag_CPU_arch 与build root 不移植 所以才会出错
但是buidroot .config 配置 BR2_ARM_CPU_ARMV5 是正确的，编译出来确实ARMV7的 ，真是奇怪了
