多谢 @fly_to_bluesky 分享！
可以详细列出来调用了哪些命令吗？
这样方便后来到这个帖子的同学参考.
直接把我保存好的文件发到这里：
https://whycan.com/files/members/961/asound.zip
下载解压后 直接restore就可以了
我上面提供的镜像里面已经有lsz 和 lrz工具，可以通过串口使用zmodern传进去。
@晕哥，非常感谢，问题已经解决了，确实是我的配置问题。
amixer list 打出来大家看看。

@晕哥 麻烦您了
@晕哥，昨天启动的问题已经搞定了。
是我rootfs的地址错误了，修改正确了，就能正常启动了。
现在就是声卡不能正常录音，我使用alsamix配置了mic 开启，还是不能正常录音。
刚开始我实现主线的uboot和主线的内核发现dts中缺少很多设备，根本没法使用，只能简单测试一下。
后来转向了 BSP kernel
使用@晕哥 提供的 f1c100s_c600sdk_16M_micropython.bin 启动发现有一个声卡，但是该镜像文件系统中没有alsa工具。
为了简便处理，我直接把晕哥这个镜像中的rootfs更换成我的带有alsa工具的rootfs。
替换rootfs后的镜像如下：
https://whycan.com/files/members/961/f1c100.rar
发现 aplay能使用的 rootfs中的 /usr下已经有一个400HZ的测试音频，但是发现arecord 不能录音不知道内核默认是line in 还是 mic 我两个都测试了没有声音，大家一起测试解决问题。
晕哥，我使用了你的SPI FLASH 镜像能发现一个声卡。
但是我自己编译的解析dtb的时候出错了。
uboot是主线的，kernel是你提供的bsp里面的，dts也是 bsp kernel里面的，rootfs是我确定能用的一个，已经把alsa工具集放进去了。
使用的交叉编译环境为 (Linaro GCC 7.2-2017.11)
启动过程中出问题了，

能请您帮我分析一下嘛！
