ESP32-S3 的串口0或串口1，无法实现Light sleep模式下唤醒

[vistawang]

ESP32在Light sleep模式下无法通过串口唤醒，按照文档该设置的都设置了，网上搜索了半天，找不到任何解决办法，甚至怀疑是不是芯片的BUG了。下面是启动日志，麻烦懂得高手指点一下，不胜感激

明确一下芯片类型，标题说的 S3，问题第一句是32，如果是32的话是不支持的，S3 是支持的，例程的话在master/system/light_sleep 上应该已经有了，早一点的IDF版本上有这个接口，但是驱动还不支持，在master上是可以用的

非常感谢您的回复，所用的芯片是 ESP32-S3 FH4R2，用的 esp-idf 版本是 v4.4.3
自带的 esp-idf-v4.4.3\examples\system\light_sleep 例程里面没有串口唤醒的 示例代码
我用ESP-IDF master 版本再试一下吧，谢谢指点！
