RK 3328cc and rtc ds3231

penguin

ds3231 is a simple i2c device, and it should be okay to work with the roc-rk3328-cc board.

The kernel driver is drivers/rtc/rtc-ds1307.c.
So you need to enable CONFIG_RTC_DRV_DS1307 in kernel config,
and add the corresponding i2c node in the device tree.

Have you done that and reflashed the kernel?
