esp32s3 light_sleep ,出现RTCWDT_RTC_RST重启原因

Postby zhaoyangeng » Tue Dec 06, 2022 3:10 am

平时工作在light sleep模式,定时器5秒唤醒一次,然后做短时间的IO引脚访问,发现程序偶尔会重启,打样如下:


[Rx][16:42:12.824] ESP32 will light sleep now!
[Rx][16:42:17.866] ESP32 will light sleep now!

请帮忙查询一下原因

就是读取IO引脚的电平。
我好像找到原因了,因为这个IO引脚设置成了RTC_GPIO,在light sleep时,外部信号改变了这个RTC_GPIO的电平,休眠唤醒的那一刻就出现了重启。我把这个IO引脚设置成普通的GPIO,之后就没有出现过去重启。
是这个原因吗?能帮忙确认吗?
