标题: [懇請開示] 想開啟 USB Gadget Drivers (Audio Gadget)
請教大神:

應如何開啟並測試. 感謝大神

作者: woody.lee 时间: 2016-5-20 10:54
目前 make menuconfig -> search gadget -> (1) -> 選 Audio Gadget -> Save & Exit

  x x       <*> USB Gadget Drivers (Audio Gadget)  --->                                  x x
  x x                Audio Gadget                                                          x x
  x x       [ ]    UAC 1.0 (Legacy)                                                    x x

重新build kernel 放上板子上跑, 結果如下
root@firefly:~# cat /proc/asound/cards
0 [UAC2Gadget    ]: UAC2_Gadget - UAC2_Gadget
                  UAC2_Gadget 0
1 [RKES8323    ]: RK_ES8323 - RK_ES8323
                  RK_ES8323
2 [RKHDMISPDIF ]: RK-HDMI-SPDIF - RK-HDMI-SPDIF
                  RK-HDMI-SPDIF

但連接 rk3288(otg) <-> Win7 並沒有USB偵測出現新的音效裝置

懇求大神開示 Orz

繼續 @@"
衝了許久的浪, 上岸一會, 小歇片刻
============{以上廢話}============
在
echo 1 > /sys/bus/platform/drivers/usb20_otg/dwc_otg_conn_en
之後,
M$ 系統提示有新的 USB 硬體接入, 但是 {音效，視訊及遊戲控制器} 驅動裝置[ Source/Sink ] 顯示為 (!)驚嘆號
應該是對應到 ./drivers/usb/gadget/f_uac2.c: [STR_ASSOC].s = "Source/Sink",

dmesg 顯示:
在 afunc_set_alt 裡面印出了 snd_uac2 snd_uac2.0: free_ep:946 Error!

懇請大神釋疑

作者: woody.lee 时间: 2016-5-23 10:36
既然接 Windows 系統驅動顯示是(!)驚嘆號, 就改接 Linux 系統試看看:

dmesg顯示

在 rk3288 上面執行:
arecord -D plughw:2,0 /root/test.wav -v
然後, 在 Linux 上面執行:
aplay -D plughw:2,0 /root/Media-Convert_test3_PCM_Stereo_VBR_16SS_11025Hz.wav -v

把檔案放到windows上來播放聽看看, 好像有點東西了~~

有大神知道這個嗎??

昨天搞了一天沒弄出甚麼東西, 真是讓人沮喪 Orz

請大神指點迷津, 目前狀態:

改成 insmod 方式作驗證

更新一下進度:
insmod後, rmmod 就會出現在 dmesg裏

更新下進度:
1. RK3288下 arecord 可以錄到從 OTG port 進來的聲音
2. RK3288下 aplay 會有下列訊息:

根據網路上查到的資料
來源引用: http://blog.csdn.net/azloong/article/details/6277457
overrun（录制时，数据都满了，还没被alsa驱动读走）和underrun（需要数据来播放，alsa驱动却不写入数据）

到底問題在哪呢 @@?

另外, dmesg 常可見

[14196. ...

楼主现在还在吗，这个问题解决了吗？？？？？
