Rtc shield (Hardkernell) on Openmediavault Erasmus

Unread postby marcellom » Tue Nov 07, 2017 6:15 am

Hi :)
Im very proud with my little odroid c2 Openmediavault nas and now is time to add a real time clock to automatize rsync works. I have the rtc shield but in HK internet site the instructions are for Ubuntu.
I have tried to follow the instructions but a system error stopped me. Anyone can help me to do the work ? Im near to the total noob with linux. I assume that there is a different way to install rtc shield and i know that Ubuntu is different to Debian (openmediavault)... please, help me!

Hi Odroid, tnx for prompt answer... this evening when ill be at home ill take a picture of the error code... if i remember well Debian dont like this argument "/i2c@c1108500/pcf8563@5" in second line of the code and give me an error code.
I will be more precise later.. tnx ahain :)

I've no experience of OMV on C2.
But I guess the dtb file could exist in /boot directory not /media/boot directory in OMV image.

I have found a solution in this forum...
viewtopic.php?t=22387

But the job works with Ubuntu upgrading the kernell with "dist-upgrade"...
Sob! Any suggestion? :/ OMV run with Debian kernell...

Since OMV is based on Armbian OS, you might need to post a request on Armbian forum.

Try to run below two commands to check whether OMV kernel has the driver modules or not.
Code: Select all
sudo modprobe aml_i2c
sudo modprobe rtc_pcf8563

Hi, someone could post a link to download the driver for rtc shield? Omv is now a Debian distro and the driver seems not available...
Sorry for trouble.. have a little patience...

Armbian seems to have "aml_i2c" driver as a built-in.
After probing the "rtc_pcf8563" module, try "hwclock" commands to check the functionality.
