esp32s3进入light_sleep时，出现RTCWDT_RTC_RST重启原因？

是这样的时间戳，需要串口工具自动生成，不是固件里面打。

比较奇怪，当 stage_timeout_ticks 比较小的时候，是能造出 RTCWDT_RTC_RST 的，但你这里 stage_timeout_ticks 也是正常的。

嗯，SDKconfig里面配置的RTC时钟源也是使用内置150Khz RC oscillator

暂时没有太好的想法，能否做以下尝试：
1、使用最新的 release/v4.4 分支，暂不确定是否有后期的改动对此问题有影响；
2、sleep 过程中，wifi stop 后，再加上 wifi deinit，醒来后重新做 wifi init；
3、开发板上，先焊接和安信可开发板或 ESP DevKitC 相似的电路，确保最小系统没问题，然后再逐步添加外围电路，做逐步的排查；
