And here's the input from Radxa: https://forum.radxa.com/t/hi-has-anyone-run-into-rtc-trouble-with-rock-3a/8522/42 So RTC part of rk809 can be disabled completely in the device tree.

I would gladly do, but my knowledge of git is close to zero. Do you mind if I ask for some guidance directly?

After restoring from backup got this message: Learn more leads here: https://www.home-assistant.io/more-info/unsupported/cgroup_version I used Ignore and it disappeared. Also upgraded the HA Core: After the upgrade installed "File editor" add-on successfully.

It works.

Yes, will try. Do I understand correctly that I need to download Docker and HA extensions to userpatches/extensions directory and then build an image for XU4?

Great idea! Any chance Odroid XU4 will be added to the list?

Started with this. Somehow timedatectl and hwclock ignore /dev/rtc symlink and use rtc0. For hwclock I can use command-line argument --rtc=/dev/rtc1, but didn't find how to change default settings for timedatectl.

Hi all! There's a dedicated RTC chip in Rock3A (HYM8563TS), but unfortunately it doesn't work right with the standard Armbian image. The chip is correctly identified, but the problem is with the RK809 PMIC, which also contains an RTC. During boot RK809 is labeled as rtc0, and HYM8563TS as rtc1, and by default kernel uses rtc0 for hwclock manipulations. Since RTC battery is connected to HYM8563TS, after power cycle RK809 is reset to 2017-08-05 09:00:00. | _ \ ___ ___| | __ |___ / / \ | |_) / _ \ / __| |/ / |_ \ / _ \ | _ < (_) | (__| < ___) / ___ \ |_| \_\___/ \___|_|\_\ |____/_/ \_\ Welcome to Armbian 23.11.1 Bookworm with Linux 6.1.63-current-rockchip64 System load: 12% Up time: 0 min Memory usage: 6% of 1.93G IP: CPU temp: 41°C Usage of /: 13% of 15G Last login: Thu Nov 30 01:59:45 CET 2023 on ttyS2 root@rock-3a:~# timedatectl Local time: Thu 2023-11-30 02:02:23 CET Universal time: Thu 2023-11-30 01:02:23 UTC RTC time: Sat 2017-08-05 09:00:58 Time zone: Europe/Brussels (CET, +0100) System clock synchronized: no NTP service: active RTC in local TZ: no root@rock-3a:~# hwclock -r --rtc=/dev/rtc0 2017-08-05 11:01:08.022461+02:00 root@rock-3a:~# hwclock -r --rtc=/dev/rtc1 2023-12-17 18:25:06.420734+01:00 root@rock-3a:~# ls -l /dev/rtc* lrwxrwxrwx 1 root root 4 Nov 30 02:01 /dev/rtc -> rtc0 crw------- 1 root root 252, 0 Nov 30 02:01 /dev/rtc0 crw------- 1 root root 252, 1 Nov 30 02:01 /dev/rtc1 root@rock-3a:~# dmesg | grep rtc [ 2.602457] rk808-rtc rk808-rtc: registered as rtc0 [ 2.605220] rk808-rtc rk808-rtc: setting system clock to 2017-08-05T09:00:08 UTC (1501923608) [ 2.617968] rtc-hym8563 5-0051: registered as rtc1 There is a parameter in kernel configuration file which specifies RTC to use: CONFIG_RTC_HCTOSYS=y CONFIG_RTC_HCTOSYS_DEVICE="rtc0" CONFIG_RTC_SYSTOHC=y CONFIG_RTC_SYSTOHC_DEVICE="rtc0" Straightforward solution would be to compile kernel with above parameters set to rtc1.

Could anybody suggest how to force the system to detect HYM8563TS as rtc0?
