Resolved! Using stm32g0 RTC as an external RTC for another system/board
I noticed this driver https://github.com/EmcraftSystems/linux-emcraft/blob/master/drivers/rtc/rtc-stm32f2.cIs it possible to configure the stm32g030c8 to be an i2c slave and provide it's RTC to an external system that runs linux and uses this driver?...
