Hi,
I am using RTC PCF85263 in our imx6 Quad custom board.
I am always getting the below error.
Oscillator stop detected, date/time is not reliable.
Oscillator stop detected, date/time is not reliable.
rtc core: registered rtc-pcf85263 as rtc0
PCF85263 RTC (irqpin=None irq=0)
Oscillator stop detected, date/time is not reliable.
hctosys: unable to read the hardware clock
Oscillator stop detected, date/time is not reliable.
This error will comes when we write the date and try to read the same. Below the steps followed
1. Set current date using "date -s" command
2. hwclock -w
3. hwclock
Could you please help for the same.
Best Regards,
Rizwan M
Hi Rizwan
one can try to debug it using AN4553 Using Open Source Debugging Tools for
Linux on i.MX Processors
https://www.nxp.com/docs/en/application-note/AN4553.pdf
i2c communication can be tested with sdk baremetal test (1.1.0_iMX6_Platform_SDK.zip)
Best regards
igor
