I just setup my raspberry pi with the gertduino and I tried the given blink example. It works fine and now I wanted to use the rtc from the gertduino to set the time from the raspberry. How ever I installed i2c-tools and when I use i2cdetect the table shows 2 entries both UU in 20b and 30b. Now I just wanted to use the command:

sudo hwclock -r

and the response is:

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

hwclock: Use the --debug option to see the details of our search for an access method

I would be really happy if anyone could give me some suggestions or maybe someone had the same problem configuring the rtc. Cheers Max

Found the answer. It was a mistake in the setup file.
