[嵌入式]8155 开发调试

1.QNX 端播放音乐：

wave?/etc/yesterday.wav

2、QNX 查看GPIO状态

cat /dev/gpio/tlmm/38/value

echo 1 > /dev/gpio/tlmm/38/value
cat /dev/gpio/tlmm/38/value

也可以使用msmgpiotool工具，调试

msmgpiotool <command> <gpio> <arg>
msmgpiotool read 8
GPIO 8 is Low
$ msmgpiotool set-dir 8 1
Set GPIO 8 direction to Out [1]
$ msmgpiotool write 8 1
Wrote GPIO 8 to 1
$ msmgpiotool read 8
GPIO 8 is High
pmicgpiotool?可以测试pmic?gpio状态
?

3.?A2B?测试

a2b-app?

Following are sample way to verify:
Terminal 1: a2b-app (this step could be skipped if a2b-app has been enabled in audio-hal)

Terminal 2: run
tinymix 'QUAT_TDM_RX_0 SlotMapping' 0 8 16 24 32 40 48 56 65535
tinymix 'QUAT_TDM_RX_0 Channels' 'Eight'
tinymix 'QUAT_TDM_RX_0 Audio Mixer MultiMedia1' 1
