Hello, i use 3328cc and i need use module rtc ds3231.
I connect rtc to pin SCL1, SDA1, 5V, GND.
The RTC module is already present on the board. And is registered rk808-rtc as rtc0.
My module rtc ds3231 shulde be registered as /dev/rtc1, But this does not happen.
If I use "i2cdetect -y -r 1", then the module is determined by the address "0x68"
To setup device i use command
"echo ds3231 0x68 > /sys/class/i2c-adapter/i2c-1/new_device"
But nothing happens. Device is not defined as /dev/rtc1
And the address "0x68" has not changed to "UU"
Question. Will the board 3328cc work with this module ds3231?
What do i need to do? Install additional drivers?
Thank you. |
