Regarding imx6ull's RTC clock

zhichaohuang — Sun, 02 Jun 2019 06:31:15 GMT

Hi,

The RTC_XTALI and RTC_XTALO were kept floating in my custom hardware.In the case,some of boards will switch internal low frequency ring oscillator to an external clock source which is inaccurate.Consequently,if I enable watchdog,it will restart within random seconds.

So is there a way to disable switching internal low frequency ring oscillator to an external clock source in software?

Regards,

Huang

Hi Huang

I am afraid there is no way to disable switching ring oscillator, sorry.

Best regards
igor
