The question is: How to use the same SD image when you don't know which RTC module will be connected on top of Raspberry PI?
I have two modules in use in config.txt:
dtparam=i2c_vc=on
dtoverlay=i2c-rtc,ds3231
and
dtparam=i2c_vc=on
dtoverlay=i2c-rtc,ds1307
I have tried specifying both(with dtoverlay=merged) but an error happens and /dev/rtc0 didn't appear. One by one they worked like a charm, but I don't want to have two different images. Any Ideas?
