Cant get raspbee ii rtc working:

Whats worng ?

The GCFFlasher Version is to old. Please follow this guide to update the RaspBee2FW to the latest version: https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/Update-deCONZ-manually#update-in-raspbian To get the latest GCFFlasher install the latest deconz version: https://phoscon.de/de/raspbee2/install#raspbian (scroll to deconz install)

Then don't forget sudo hwclock --systohc before hwclock --verbose.

I also tried the latest GCFFlasher from the deCONZ package, which results in the same error.

hwclock --systohc and hwclock --verbose were done.

what is the output of GCFFlasher_internal -r ?

[mspbonn]

root@gateway:~# dmesg | grep rtc

Is that the bee ii device ?

root@gateway:~# dmesg | grep AMA

This is still GCFFlasher v2_11. It does not work with the RaspBee2 and also the newest FW is needed to run the RTC. The newest veresion of GCFFlaher is 3.17 Which version of deCONZ do you have installed? If installing via apt repository does not work you can download the newest installer via curl http://deconz.dresden-elektronik.de/raspbian/deconz-latest.deb -o deconz-latest.deb and then install it manually with sudo dpkg -i deconz-latest.deb

GCFFlasher_internal -r should then return something like this:

sudo GCFFlasher_internal -r GCFFlasher V3_17 (c) dresden elektronik ingenieurtechnik gmbh Reboot device RaspBee (RaspBee) deCONZ firmware version 26610700 Bootloader version 0x00030003, app crc: 0x769F0F78

The Raspbee2 can be /dev/ttyAMA0 or /dev/ttyS0

Seems that the bee ii needs newer firmware, because it still not works:

Where to get the latest firmware ?

[mspbonn]

With the latest fireware from http://deconz.dresden-elektronik.de/deconz-firmware/deCONZ_RaspBeeII_0x26610700.bin.GCF it works:
