Hi, I took an upgrade with OpenBSD 6.9 in my Raspberry Pi 4B however DS3231 real-time clock wasn't detected. This time I'm using the default U-boot firmware (Das U-Boot rev 0x20210100). The same parameter I used in the config.txt file and the dtbo https://github.com/raspberrypi/firmware/blob/master/boot/overlays/i2c-rtc.dtbo .
dtoverlay=i2c-rtc,ds3231 Attached herewith is the dmesg file. Thanks and best regards, Archimedes
