rk3308执行录音命令后重启

zhangfengzan

我的RK3308-ROC-CC串口执行录音命令后会重启，麻烦帮忙看下是什么原因导致的，附件是log，而且是必现，声卡都是注册成功的。

请问你这是录音还是放音会自动重启，板型是ROC-RK3308-CC吗，烧写公版固件是否会出现

公版固件是不会的，是ROC-RK3308-CC的，搞错了是播放命令

我也看到了，就是不知道具体是什么原因导致的，没查到原因

那你有改动过什么东西吗，比如dts，driver之类的

有的，就是修改了设备树，注释掉了pdm声卡，打开了i2s_8ch_1单独添加了一个自己的tdm声卡。声卡启动能注册上，就是一播放就会重启

diff看一下修改内容更直观，这样不好看下载还要扣灯泡

看一下
ls -l /dev/snd
cat /proc/asound/cards

硬件怎么接的，是不是接了外部的codec，如果是看一下你codec的配置吧
