How to get MOD_RTC2 working on A20 Board running latest bullseye

[reisenbauerh]

Rtc always sets 1970 at boot time :-(


root@a20-olinuxino:~# uname -a
Linux a20-olinuxino 5.10.105-olimex #085648 SMP Tue Jan 10 08:58:08 UTC 2023 armv7l GNU/Linux

root@a20-olinuxino:~# ls /dev | grep rtc*
rtc
rtc0

root@a20-olinuxino:~# cat /var/log/syslog | grep rtc

Hello,

These are all good questions, unfortunately, you have to figure it out by yourself. We don't have the resources to analyze every software problem or request a customer might encounter and fix it for him/her. We can only provide a free and open source basis and a simple test which demonstrates that the hardware parts work fine together.

Best regards,
OLIMEX
