Hi list,
My ds1307 rtc module plugged into my Raspberry Pi 4B (4GB) model is not
getting recognized by the the Bookworm arm64 kernel.
In Raspian and Ubuntu the driver is built as a module with
CONFIG_RTC_DRV_DS1307=m and loading happens with
dtoverlay=i2c-rtc,ds3231 in config.txt.
Debian does compile it into vmlinuz with CONFIG_RTC_DRV_DS1307=y but the
hardware detection fails with no mentioning of rtc in dmesg.
i2c_dev and i2c_bcm2835 are loaded, but i2cdetect -y 1 does not detect
the rtc on the bus.
Is this a bug or where there no plans to add this to the rpi4 feature set?
I'm not subscribed to the list, please CC your replies.
Thanks and Regards
Tuxo
