I'm installed Armbian_23.02.2_Orangepi5_jammy_legacy_5.10.110_xfce_desktop to Orange Pi5. I have attached external RTC module with DS3231 on I2C5 (/dev/i2c-5) and try it. https://forum.armbian.com/topic/7349-rtc-ds3231-how-to-install-tinker-board-stretch-414/#comment-56094 (Instead of I2C-0, it was I2C-5.) However, the DS3231 does not recognize it. I type i2cdetect -y 5, it remains at 68 without becoming a UU. Is there any solution?
