I got the latest resinOS 2.12.7+rev1.dev version running on an Raspberry Pi Zero W and attached an RTC (DS3231) via I2C to the RPi. I also set it up via the config.txt with:
- yes I am using it as ds1307, I found out that this works somehow better - and the ds3231 does only work sporadicly (dunno why, its just what I figured and thought I document it here, in case someone else was having the same problems).
Anyway: What I need to do is to disable any kind of timesync / read / write to the RTC by resinOS at all. The RTC itself is accessed via an container under special circumstances and setup, and this works very well. However, any access by resinOS will disturb this. Which services do I need to disable to prevent resinOS from accessing the RTC by itself?
Thank you very much and have a nice day
