http://mailman.uclinux.org/pipermail/uclinux-dev/2011-February/002993.html Now i have i2c-0 device created. i2c-core: driver [rtc-ds1307] registered i2c /dev entries driver i2c-core: driver [dev_driver] registered TCP cubic registered NET: Registered protocol family 17 drivers/rtc/hctosys.c: unable to open rtc device (rtc0) I also created rtc0, i don't understand why it cannot be open.
