T113 I2S 音频输出至 Lontium 芯片 / T113 I2S Audio Output to Lontium chip
-
嗨。我正在尝试配置我的 T113，以将 I2S 音频输出到 Lontium LT9611UXC MIPI 到 HDMI 芯片。我已将我的 DTS 配置为输出 I2S。但是查看 dmesg 我发现我的 DOUT 引脚未正确初始化：
[ 1.881261] sun8iw20-pinctrl pio: unsupported function i2s2 on pin PB4有什么帮助或想法吗？最后是我的 dts：
Hi. I'm trying to configure my T113 to output I2S audio to a Lontium LT9611UXC MIPI to HDMI chip. I've configured my DTS to output I2S. However looking at dmesg I see that my DOUT pin isn't properly initialised:
[ 1.881261] sun8iw20-pinctrl pio: unsupported function i2s2 on pin PB4Any help or ideas? Below is my dts:

@whycanservice2 感谢您的回复。这似乎已经修复了错误。我不再收到错误，我可以使用“cat /sys/kernel/debug/pinctrl/pio/pinmux-pins”来查看引脚是否已分配给 I2S。
但是我仍然无法通过 I2S 播放音频。我正在使用 tplayerdemo 播放带音频的视频。我会继续调查，但有什么想法吗？
此外，是否有资源或文档可以让我稍后自己查找此信息？我查看了 Tina SDK 手册，但似乎找不到此信息。
非常感谢您的帮助！

@dazb3 需要切换声卡才可以使用i2s播放。给你一份文件吧。D1_Linux_AUDIOCODEC_开发指南.pdf

@dazb3 there's a i2s doc on 100ask.net https://forums.100ask.net/uploads/short-url/3Da0tOrvGPKeV7Be36UVkzivSE6.pdf
to test i2s, why not try aplay or tinyplay?

谢谢你们的帮助。附件中的文档和链接非常有用。
我用示波器检查了引脚，可以看到 I2S 正在输出。在咨询了 Lontium 后，我终于能够将正确的 I2S 格式输入芯片中。
作为参考，该芯片是 Lontium LT9611UXC。
