Hi,there
I use external 32.768KHz crystal as rtc clock.It's Cl is 9pf and Rl is 35Kohm.
Most of ESP32 take 2-3s to work,but some ESP32 32.768Khz don't work.
What's crystal parameters?
Thanks in advance for your help!

Re: ESP32D0WD RTC 32.768KHz
Hi PaulShaw,
What about the driving level of the 32.768kHz crystal that you use?
The rtc_clk.c can be used to adjust the drive strength, but this file will only be included in our next version of IDF.
Currently, you can apply rtc_clk.c by sending e-mail to our FAE.
Thanks.
