i have connected rtc backup battery with udoo neo board connector but it does not keep time when power switching on state to off then, i saw some thread in udoo forum they said rtc under development. still that problem solved or not please tell. thank you...
I have not heard it has been solved so I suspect it is still an open issue. A workaround is to attach an external I2C/SPI RTC unit. SPI RTC will only work on linux side. If you want to use the arduino side you only can use I2C.
hi, thanks for your replay could you tell me how to interface rtc like ds1307 not user space directly to kernel space like system update time from ds1307 after booting finished. thank you
