Trouble Setting up RTC in Raspberry Pi

[dharashah]

Hi I am new to raspberry Pi.
I have Raspberry Pi 2 Model B. Have installed Raspbian Wheezy

I need to setup RTC Module in it.

This is what I did.
1. Enabled I2C from raspi-config and set it to load by default
2. Changed /etc/modules and added following lines

Code: Select all

i2c-bcm2708
i2c-dev

3. Then I installed 12c-tools and python-smbus

Code: Select all

sudo apt-get install -y python-smbus i2c-tools

And restarted Pi
4. After that I shutdown Pi , and connected the RTC
VCC->5V, GND->GND, SDA->GPI02 and SCL->GPI03
5. At this point when I run

Code: Select all

sudo i2cdetect -y 1

I see a proper ID #68
6. Then I ran following commands:

Code: Select all

sudo modprobe rtc-ds1307
sudo bash
echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
exit
sudo date -s "Sat Sep  12 16:41:00 UTC 2015"
sudo hwclock -w
sudo hwclock –r

At this time, I am getting proper time with the command sudo hwclock -r
7. Then I added rtc-ds1307 to file /etc/modules
And following lines in /etc/rc.local
echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
sudo hwclock -s
date

now when I reboot the Pi, the time is not showing from RTC.
Aslo the command sudo i2cdetect -y 1 shows UU instead of #68

I am not sure what I did wrong. I had followed two tutorials
http://www.raspberrypi-spy.co.uk/2014/1 ... pberry-pi/
http://thepihut.com/blogs/raspberry-pi- ... spberry-pi

Thanking you for any support in advance.
I urgently need this

i don't know, but maybe you have to uninstall the fake-hwclock

Code: Select all

sudo apt-get remove fake-hwclock
sudo update-rc.d -f fake-hwclock remove
sudo rm /etc/cron.hourly/fake-hwclock
sudo rm /etc/init.d/fake-hwclock

Greetings.

OP didn't do anything wrong. It's just the Raspbian is upgraded.

Both of the tutorials you've used are out of date.

Add

Code: Select all

dtoverlay=i2c-rtc,ds1307

to config.txt, reboot and your RTC device should show as

Code: Select all

root@apollo ~ # i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- UU -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
root@apollo ~ #

There's no modprobe or echo command needed to get that working.
