Hello, I have a Banana Pi M64 with android 6.0.1 running and the system takes the date from internet, but if the system starts without internet connection the date is January 1st 2010. I know that I can solve it with an RTC, but I don’t know if the system will recognize it.
I thought 2 possibilities:
Use A64 integrated RTC. I have seen that the processor has an internal RTC, and if I keep powering the RTC-VCC pin it should keep date untill next time that the internet connection returns. The problem is that I have found the RTC-VCC in the schematics but I don’t know where can I find it on the board. Maybe if I know the exact place I can solder a battery to this point and keep it powered.
Use external rtc like DS3231 connected through i2c in the gpio pin headers but I don’t know how to get the date from the i2c bus to Android or if I need an specific driver.
Can anybody help?
Thank you in advance.
