openwrt master 分支移植错误 #3

Closed myzhang001 closed 4 years ago

myzhang001 commented 4 years ago

我按照你给的说明移植没有成功，是哪里漏了呢

[ 21.612366] mt76x8-wm8960 sound: failed to find audio codec device [ 21.618739] mt76x8-wm8960: probe of sound failed with error -22

redchenjs commented 4 years ago

你用的是哪块板呢？ 试一下能不能手动加载：

modprobe snd-soc-wm8960
modprobe snd-soc-mt76x8-wm8960
myzhang001 commented 4 years ago

我使用的是widora neo

myzhang001 commented 4 years ago

你是刷了整个固件还是只安装了这个驱动包？kmod-sound-mt7620这个依赖包有没有安装？

myzhang001 commented 4 years ago

我是刷了整个固件，kmod-sound-mt7620 我是安装了的

redchenjs commented 4 years ago 
ls /lib/modules/4.xx.xx/ | grep wm8960

里面应该有

snd-soc-mt76x8-wm8960.ko
snd-soc-wm8960.ko

这两个模块，看是不是少了

myzhang001 commented 4 years ago

snd-soc-mt76x8-wm8960.ko 找到了有的 但是没有 snd-soc-wm8960.ko 这个

redchenjs commented 4 years ago

snd-soc-wm8960.ko这个模块是打包在kmod-sound-mt7620里面的,顺便看看有没有这几个模块

snd-soc-ralink-i2s.ko
snd-soc-simple-card-utils.ko
snd-soc-simple-card.ko

也是打包在kmod-sound-mt7620里面的

myzhang001 commented 4 years ago

我编译了 komd-sound-mt7620 但是还是没有出来 snd-soc-wm8960.ko

这就奇怪了，不知道你用的是哪个版本的OpenWrt源码，我编译试试 master的代码是没问题的:

[   36.799994] gdma-rt2880 10002800.gdma: revision: 3, channels: 16

myzhang001 commented 4 years ago

我用的是最新的 git 官方拉下来最新的master 分支的代码，你可以试试

redchenjs commented 4 years ago

不是说18.06吗？

myzhang001 commented 4 years ago

i2c-mt7621 10000900.i2c: clock 100KHz, re-start not support 这个我这边也没有看到，是缺了哪个配置呀

myzhang001 commented 4 years ago

我确认了下是master 分支

redchenjs commented 4 years ago

@myzhang001 确实是缺少i2c依赖的原因，最新代码已解决该问题。

myzhang001 commented 4 years ago

编译完了需要我单独安装么

redchenjs commented 4 years ago

更新代码后make menuconfig一下，依赖会自动选上，重新编译就行了，不用手动安装

myzhang001 commented 4 years ago

但是我重新编译了还是没有，尴尬了 我看了 ipk 包是有的

myzhang001 commented 4 years ago

snd-soc-wm8960.ko 一直没出来

redchenjs commented 4 years ago

Deepin 截圖_dde-desktop_20190919142221 kmod-i2c-mt7628这个模块没有自动勾选吗

myzhang001 commented 4 years ago

已经自动勾选了

这是logo

redchenjs commented 4 years ago

你试试make clean后再编译

myzhang001 commented 4 years ago

好的，我试试

myzhang001 commented 4 years ago

@redchenjs make clean 后 还是不行哦，不知道是什么原因

redchenjs commented 4 years ago

那用我的配置文件试试吧，测试过可用 Widora-NEO-16M.zip

myzhang001 commented 4 years ago

好的，非常感谢，您是否有csdn 或者博客 ，我好跟随你的脚步学习O(∩_∩)O哈哈~

redchenjs commented 4 years ago

暂时没有

myzhang001 commented 4 years ago

可以把你的dts 文件也发给我参考下不，mt7628an_widora_neo.dtsi mt7628an_widora_neo-16m.dts mt7628an.dtsi

现在已经挂载成功了，但是没有声音

redchenjs commented 4 years ago

初始是静音的，需按readme中设置，如要保存设置可以添加到开机脚本中

myzhang001 commented 4 years ago

我按照readme 设置了，同样没有声音

redchenjs commented 4 years ago

@myzhang001 我把dts文件上传了，其实README中对MCLK和ADCLRC时钟的说明就是针对NEO这块板子的，不设置时钟是没有声音的，你可以参考一下上传的dts添加缺失的项。
