Raspberry Pi 3 - hwclock: Cannot access the Hardware Clock via any known method #8

Closed thezepter closed 8 years ago

thezepter commented 8 years ago

i can´t get it to work with my Pi 3 (raspian jessie) if i would set the time with

hwclock --systohc Error: hwclock: Cannot access the Hardware Clock via any known method.

hwclock -r Error: hwclock: Cannot access the Hardware Clock via any known method.

any idea ?

i2cdetect -y 1

error

/etc/modules

i2c-bcm2708 i2c-dev

systemctl status rc-local.service

error2 . . . . . I tried this method: the result is:

hwclock --systohc <-- OK hwclock -r <-- OK

after reboot:

hwclock -r <-- hwclock: The Hardware Clock registers contain values that are either invalid (e.g. 50th day of month) or beyond the range we can handle (e.g. Year 2095).

i2cdetect -y 1 error3

I´ve found a soloution for the Raspberry Pi 3 an this PiFace RTC here I used a fresh installation of raspian (Jessie) lite, and now it works.
