i.MX6Dual RTC_XTALI,RTC_XTALO pins

[佐藤智幸]

Dear community,

I have a question about i.MX6Dual.

When I do not use external RTCXTAL(32.768k), is the RTC_XTALI,RTCXTALO pin good as a float?

Thanks and Best Regards,

Hi 佐藤智幸

you should always use RTCXTAL(32.768k) due to

ERR007926 ROM: 32 kHz internal oscillator timing inaccuracy may affect

SD/MMC, NAND, and OneNAND boot

Best regards
