2017/10/27 15:22

版本：V1.0

 

 

开发板使用：BPI-M2U

 

 

1、原始编译r40平台的tinav2.1系统：

rootroot@cm-System-Product-Name:/home/wwt/r40$ tar zxvf r40_tinav2.1_leo_20170112.tar.gz 

rootroot@cm-System-Product-Name:/home/wwt/r40$ mv tina/ r40_tinav2.1

rootroot@cm-System-Product-Name:/home/wwt/r40$ cd r40_tinav2.1/

rootroot@cm-System-Product-Name:/home/wwt/r40/r40_tinav2.1$ source build/envsetup.sh

rootroot@cm-System-Product-Name:/home/wwt/r40/r40_tinav2.1$ lunch

     13. azalea_m2ultra-tina

Which would you like?13

rootroot@cm-System-Product-Name:/home/wwt/r40/r40_tinav2.1$ make -j12

rootroot@cm-System-Product-Name:/home/wwt/r40/r40_tinav2.1$ pack

 

 

 

 

2、录音测试根据：R40_Linux_V1.0_音频模块使用文档_V1.3.pdf

9. 声卡信息查询

声卡信息查询方法如下所示：

/ # cd /proc/asound/ 

/proc/asound # cat pcm 

00-00: SUNXI-CODEC sndcodec-0 : : playback 1 : capture 1

对应 machine 层是： stream name codec_dai_name；播放录音；

/proc/asound # cat card 

card0/ cards

/proc/asound # cat cards 

 0 [audiocodec ]: audiocodec - audiocodec 

 audiocodec 声卡名称

 

/proc/asound # cd /sys/class/sound 

/sys/class/sound # ls 

card0

controlC0

pcmC0D0c

pcmC0D0p

timer

pcmCOD0c：表示 pcm 流 card 0 device 0 capture 录音接口；

pcmC0D0p：表示 pcm 流 card0 device 0 play 播放接口；

controlC0：表示 card0 控制接口；

 

/sys/class/sound # cat card0/id 

audiocodec

3、

尝试关闭HDMI声卡：

rootroot@cm-System-Product-Name:/home/wwt/ap6212a1_bpim2u_ov5640_spi01$ make menuconfig

Kernel modules  ---

Video Support  --->

（默认没有选中）

< > kmod-sunxi-hdmi....................................... sunxi-hdmi support

 

 

rootroot@cm-System-Product-Name:/home/wwt/ap6212a1_bpim2u_ov5640_spi01$ make kernel_menuconfig

Device Drivers  --->

<*> Sound card support  --->

--- Sound card support

<*>   Advanced Linux Sound Architecture  --->

<*>   ALSA for SoC audio support  --->

<*>   ASoC support for SUNXI  --->

<*>   ASoC support for hdmiaudio. 

（修改为：）

< >   ASoC support for hdmiaudio.

编译刷机之后：

root@TinaLinux:/tmp#

root@TinaLinux:/tmp# cat /proc/asound/cards 

 0 [audiocodec     ]: audiocodec - audiocodec

                      audiocodec

root@TinaLinux:/tmp#

 

HDMI数字声卡关闭之后还是没有声音！

 

 

 

 

4、对照Android的sys_config.fex修改：
