I am using a BBB running the new Debian image. I have connected a DS1307 RTC (via a "Tiny RTC I2C modules" breakout board) to I2C2, and have added "cape_enable=capemgr.enable_partno=BB-BONE-RTC" to uEnv.txt such that my BBB does see this RTC as /dev/rtc1.
I want to synchronize the system clock from *this* RTC on boot (and not the BBB's rtc-omap that is registered as /dev/rtc0), so I modified /etc/init.d/hwclock.sh such that HCTOSYS_DEVICE=rtc1. I thought that should do it... *after all, I was able to get a Raspberry Pi running Raspian to synchronize with a DS1307 on boot following these instructions: * *http://blog.elevendroids.com/2012/12/setting-up-hardware-rtc-in-raspbian/* <http://blog.elevendroids.com/2012/12/setting-up-hardware-rtc-in-raspbian/> However, my BBB keeps synchronizing with rtc-omap on boot... and doesn't seem to be running hwclock.sh, either (time after boot is back in May, not the current time as I confirm by sudo hwclock -r -f /dev/rtc1). So where is Debian actually synchronizing the time in the boot process, and how do I tell it I want to use my battery-backed clock? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
