器件型号:TLV320AIC3110

您好!

我的 tlv320aic3110编解码器存在问题。 我在嵌入式器件启动时收到以下两个错误:

[   10.079068] tlv320aic31xx-codec 0-0018: Unable to sync registers 0x1d-0x1d. -6
[   10.161668] tlv320aic31xx-codec 0-0018: Failed to restore cache: -6

根据数据表、0x1d 可以是"表7-69。 页0/寄存器29 (0x1D):编解码器接口控制2"或"表7-136。 页1/寄存器1 (0x01)到页1/寄存器29 (0x1D):保留"。

大约一分钟后、也会出现以下错误:

[   66.858820] tlv320aic31xx-codec 0-0018: ASoC: error at snd_soc_component_update_bits on tlv320aic31xx-codec.0-0018: -16

最后、在暂停/恢复之后、我遇到最后这些错误:

几天来,我一直在努力寻找解决方案,但我一直未能找到任何重要的东西。 我可以做些什么或许能够更接近这些错误的根本原因吗? 有人以前见过这样的东西吗?

如果您需要我提供的任何其他有用信息、请告诉我。

提前感谢!

    您好!

    错误-16对应于 设备或资源繁忙、 是否有其他设备占用此 i2c 端口? 此问题似乎仅与 i2c 器件有关。 您可以进行一些尝试、例如向系统添加日志以找出 i2c 异常的原因。

    谢谢
