No. DTS entry was missing. You have to wait for the next release.

blackride but you can use that command from a Ubuntu PC and locate the file meson64_odroidc2.dtb on microsd card.

i tried

Code

wget https://github.com/LibreELEC/linux-amlogic/pull/15/commits/07af642962064d035fdd165074566ef39e51b8b1.diff -O rtc.patch

But

I've tested and with the fixed Device Tree entry it's working.

It works?
Do I understand correctly that it is necessary to add this line

Code

fdtput -t s meson64_odroidc2.dtb /i2c@c1108500/pcf8563@51 status "okay"

in file "boot.ini" ?

And it should work in the next release LE?

I've stumbled across the cause of the issue I believe today:

wrxtasy, thank you very much!

But how to remake comand for our boot.ini?

Code

fdtput -t s /path/to/your/dtb/meson64_odroidc2.dtb /i2c@c1108500/pcf8563@51 status "okay"

I make

Code

# modprobe rtc-pcf8563

and

Code

But comand

Code

# dmesg | grep rtc
[    2.692209] drivers/rtc/hctosys.c: unable to open rtc device (rtc0)

don't see device.

Any ideas?

Quote from gdachs

The LibreELEC developers may not need the time from the RTC, because all their devices are connected to the internet and the time they get from there is good enough.

Gerald

Why you are responsible for all developers?
I did not ask you to respond. OK?

Quote from Raybuntu

I'm guessing it wouldn't be hard to include the module since it's just a change in the kernel config.

The news on site libreelec.tv says that the HK RTС Shield support has been added:

Add support for HK RTC shield on Odroid C2

I yesterday installed img LibreELEC-Odroid_C2.aarch64-7.90.006.img.gz

But HK Official RTC Shield is not detected:

Code

dmesg | grep rtc
[ 2.662196] drivers/rtc/hctosys.c: [color=#FF0000]unable to open rtc device (rtc0)[/color]

This means that the module rtc_pcf8563 is not loaded.

I think one that the developers do not speak the truth?
OR
Support add HK RTC Shield in release 7.90.007?

blackride · Official RTC Shield for Odroid C2 blackride September 18, 2016 at 5:56 AM

Quote from gdachs

Maybe because there is just no need for it?

Gerald

Why is there no need?
The module already exists. And what is the complexity of adding it to the official image?

Could you please add to the official release? :s

blackride · Official RTC Shield for Odroid C2 blackride September 17, 2016 at 9:11 AM

Why developers pass this problem???

blackride · Official RTC Shield for Odroid C2 blackride September 15, 2016 at 5:08 PM

Hi.
I have Official RTC Shield for Odroid C2.
Support added module PCF8563 in kernel for image "LibreELEC 7.0.1" (16.1 28.May.2016) and higher.

Can add a module to the LibreELEC 7.90.0XX (8.00)? :s

Thank you!
